• Genetic study of apple resistance to Glomerella Leaf Spot（GLS）were carried out by using 4 F1 hybrid groups（‘Fuji’בGolden Delicious’，‘Golden Delicious’בFuji’，‘Gala’בFuji’and‘Fuji’בQF-2’）generated from two highly resistant variety or selection，‘Fuji’and‘QF-2’，and two highly susceptible varieties‘Golden Delicious’and‘Gala’. The results showed that the separation ratio of resistant plants to the susceptible ones in 4 F1 hybrid groups were statistically consistent with the theoretical ratios of 1︰1，1︰1，1︰0 and 0︰1. By comprehensive analysis，the conclusions could be drawn as the follows：The apple resistance to GLS may controlled by a single recessive gene. The genotype of the resistant plants was rr，while the genotypes of the susceptible ones were RR and Rr. Using‘GoldenDelicious’בFuji’F1 hybrid groups and the Bulked Segregation Analysis（BSA）method，the marker S0506206-243 bp associated with disease resistance character to GLS were identified through screening 500 SSR primers covering the whole apple genome evenly，and the genetic distance between the marker and the resistant gene to GLS was 9.8 cM.

• To investigate the function of calcium signal of apple trees during defense process in response to Alternaria alternata apple pathotype（A. alternata AP），this study analyzed the leaf cellultra-structure，distribution change of calcium and relative expression of MdCPKs during the plant- pathogen interaction period. The susceptible and resistant cultivars to A. alternata AP，Red Delicious and Jonathan apple were used as materials. The variation of Ca2+ subcellular localization and relative expression of MdCPKs in leaves were detected by transmission electron microscope and qRT-PCR analysis when leaves were attacked by A. alternata AP. The results were as follows：The cell structure of Red Delicious and Jonathan remained intact and calcium antimonate deposits localized mainly in the vacuoles and intercellular spaces of the mesophyll cells under the resting conditions，while the density of calcium precipitation in intercellular spaces is higher in Jonathan than that in Red Delicious. Calcium gathered in the cytoplasms and remarkable reduced in the vacuoles in Red Delicious，while it not only gathered in the cytoplasms but also in the sieve tubes in Jonathan，declined in the vacuoles and intercellular spaces，and tended to locate in the outside of the cell wall and vacuole membrane when leaves were inoculated with A. alternata AP at 8 hpi（hours post inoculation）. Calcium in the leaf cells of Red Delicious tended to move from the cells to the intercellular spaces at 18 hpi，while a large number of calcium localized in the cytoplasms，vacuoles and sieve tubes in Jonathan at this time. When inoculated A. alternata AP at 24 hpi，the cell structure of Red Delicious had been distorted，plasmalemma were broken and sieve tube wall was lignified，and calcium mainly localized in the cytoplasms，while the cell structure of Jonathan still kept integrity and calcium localized in the vacuoles and cytoplasms. Some cells in Red Delicious were invaded by hyphae at 36 hpi. Calcium deposits mainly localized in the vacuoles in the undamaged cells，and distributed in intercellular spaces disorderly around the damaged cells，however，the calcium level kept dynamic homeostasis in the leaf cells of Jonathan at this time. The relative expression of MdCPKs in Red Delicious and Jonathan showed different characters during the different stages of A. alternata AP infection. Most MdCPKs reached to the highest expression level at 24 hpi in Jonathan while that delayed at 36 hpi in Red Delicious，and the relative expression of MdCPKs in Jonathan were higher than in Red Delicious. The results indicated that calcium signal involved in the response of apple to A. alternata AP infection. The increasing of cytoplasm calcium in Jonathan and in Red Delicious mainly resulted from the inflow of extracellular spaces and the release of organelle respectively when they attacked by A. alternata AP. Moreover，MdCPKs in Jonathan responded to the infection earlier and more intensely than they did in Red Delicious.

• This study explored the effects of applying reflective film before harvest on fruit
  appearance quality of peach（Prunus persica），and discussed the influencing mechanism on fruit coloration.
  Yellow outside and black inside double-layer bags were removed from fruit 12 d before harvest. Peel
  color，pigment content，enzyme activity as well as the gene expression related to fruit coloration of a
  well-colored and late-ripening peach cultivar Xiahui 8 with different treatments（non-bagging with
  non-reflective film mulching，debagging with non-reflective film mulching，debagging with reflective film
  mulching）were researched. The results showed that both debagging with non-reflective film mulching and
  debagging with reflective film mulching could significantly improve red and green color difference value（a*），a*/b*（b* is yellow and blue color difference value），chroma（C），anthocyanin（Ant）content and
  reduce hue angle（h），while debagging with reflective film mulching had higher Ant content than
  debagging with non-reflective film mulching（P < 0.05）. The two treatments up-regulated the transcript level
  of anthocyanin biosynthetic related genes（UFGT，CHS）at the beginning of the experiment，however，
  the expression of DFR，LDOX and F3H were enhanced along with the testing process. A downward trend
  on phenylalanine ammonia lyase（PAL）activity of non-bagging with non-reflective film mulching was
  observed during the experiment，however，the peel PAL activity of the other two treatments first increased
  and then decreased. What’s more，peel PAL activity of debagging with reflective film mulching was higher
  than debagging with non-reflective film mulching. These results suggested that Ant synthesis in the peel
  was the result of cooperation among several genes，and debagging with reflective film mulching had better
  effect on promoting Ant accumulation than debagging with non-reflective film mulching.

• Full-length cDNAs of Δ1-pyrroline-5-carboxylate synthetase（PpP5CS）and ornithine
  aminotransferase（PpOAT）were isolated from peach fruit using degenerate RT-PCR and RACE（rapid
  amplification of cDNA ends）method. The sequences of these two genes were then deposited in GenBank
  database with the accession number KP973954 and KP973956，respectively. PpP5CS was 2 511 bp in full
  length and encoded a predicted protein of 717 amino acids（ORF length 2 151 bp），and flanked by 123
  nucleotides at the 5′-UTR and 235 nucleotides at the 3′-UTR. The full length of PpOAT was 1 686 bp with
  ORF 1 416 bp，5′-UTR 151 bp and 3′-UTR 119 bp，which encoded a deduced polypeptide of 472 amino
  acids. Phylogenetic analysis indicated that PpOAT and PpP5CS shared high similarity with otherplants with 88% and 91% homology with MhOAT and MhP5CS，respectively. Furthermore，the effect of
  5 mmol · L-1 γ-aminobutyric acid treatment on chilling injury incidence and PpOAT and PpP5CS
  expression，which were involved in proline biosynthesis，in postharvest peach fruit stored at 0 ℃ was
  investigated. The results showed that 5 mmol · L-1 γ-aminobutyric acid treatment significantly inhibited the
  decline of extractable juice，and alleviated chilling injury in peach fruit during cold storage. Meanwhile，
  the expression of these two genes in peach fruit was induced by the treatment during cold storage. These
  results suggested that γ-aminobutyric acid treatment could increase proline biosynthesis and accumulation
  by up-regulating the expression levels of PpOAT and PpP5CS thereby promote chilling tolerance in
  cold-stored peach fruit.

• The yellow-fleshed loquat‘Zaozhong 6’and the white-fleshed loquat‘Baiyu’were used
  as materials，the accumulation of carotenoids in peel and pulp during different fruit development stages
  were detected，and the expression of 15 carotenogenic genes were analysized. During loquat fruit
  ripening，the content of β-carotene in peel and pulp of‘Zaozhong 6’increased gradually and peaked at the
  fully ripe stage，in the peel it was 68.53 μg ? g-1 FW，while in the pulp it was 11.92 μg ? g-1 FW. And in the
  peel of‘Baiyu’，the content of β-carotene increased and peaked at the fully ripe stage，reached to 38.89
  μg ? g-1 FW，while it decreased in the pulp of‘Baiyu’，from the original 0.47 μg ? g-1 FW reduced to 0.29
  μg ? g-1 FW；The content of β-cryptoxanthin in the peel and pulp of‘Zaozhong 6’and‘Baiyu’bothincreased steadily，and peaked at the fully ripe stage；However，the content of lutein decreased in the peel
  of ‘Zaozhong 6’and increased in the pulp of ‘Zaozhong 6’；It droped and then rised in the peel of ‘Baiyu’，
  and there was no significant change of β-cryptoxanthin in the pulp of‘Baiyu’. After the breaker stage，the
  mRNA levels of phytoene synthase（PSY）and chromoplast-specific lycopene β-cyclase（CYCB）were
  higher in the peel，and CYCB and β-carotene hydroxylase（BCH）mRNAs were higher in the flesh of
  ‘Zaozhong 6’，compared with‘Baiyu’. The results showed that the expression level of PSY，CYCB and
  BCH was likely to cooperatively regulate the accumulation of carotenoids.

• Abstract ( 328 ) HTML ( 1303 ) PDF (335KB) ( 1303 ) 　　　

• Anti-nutritional factors such as lectins，saponin，trypsin inhibitor and phytic acid are
  endogenous substances in kidney bean（Phaseolus vulgaris L.）. In this study，the contents or activities of
  these four anti-nutritional factors in fresh pods were detected in 56 selected cultivars. The results revealed
  significant difference of each factor in the tested cultivar population. The mean value of lectin content and
  the activity of trypsin inhibitor was 1.743 mg · g-1 and 1.680 mg · g-1 respectively. Their coefficients of
  variation（CV）were both more than 100% and each of the cultivar frequency distribution curve showed a
  main peak，but the discontinuous distributions in the extremely high and low areas indicate hierarchic
  cultivars. However，the content of saponin（mean value 3.730 mg · g-1）and phytic acid（mean value 3.102
  mg · g-1）were with CV less than 41%. Each showed a main peak in its normal distribution curve and low
  frequency continuous distribution in dual tails. Meanwhile，statistic analysis demonstrated a positivecorrelation between the lectin content and trypsin inhibitor activity in fresh pods. Furthermore，all tested 56
  cultivars clustered into three groups based on their level of four anti-nutritional factors，80% of them into
  medium level group，12% of them into low level group. The endogenous edible toxic compounds，such as
  lectin and trypsin inhibitor，are closely related to the insect resistance in field. This study suggested that it
  is possible to screen the cultivars contain less lectin and other factors but with reduced the pest resistance
  in field.

• The unpollinated ovules of cucumber（Cucumis sativus L.）line 65G × 228 were used to
  obtain haploid plants via in vitro gynogenesis. With the unfertilized ovules，a regeneration system of
  cucumber was established by analizing the effects of pretreatment temperature，induction medium，
  concentration of TDZ，KT and BA on haploid induction. The results indicated that 0.02 mg · L-1 TDZ was
  better for the initiation of gynogenesis. Induction medium and concentration of KT significantly affected
  the frequency of embryo induction. Further，the highest embryo regeneration frequency was achieved at
  IM3 medium supplemented with 0.75 mg · L-1 KT and 2.0 mg · L-1 BA. The embryos could grow root and
  develop into the complete plant on MS medium. Flow cytometry analysis showed that 18.2% of the
  regenerated plants were haploid.

• In the present study，based on the recently released pepper whole-genome sequences，
  CaWRKY gene family identification，gene classification，chromosome location，sequence alignment and
  conserved structure domains of CaWRKY proteins were predicted and analyzed with bioinformatics
  methods. The results showed that 71 CaWRKY genes were identified which were classified into three main
  groups（Ⅰ，Ⅱand Ⅲ），with the second group further divided five subgroups[Ⅱ（a），Ⅱ（b），Ⅱ（c），
  Ⅱ（d）and Ⅱ（e）]. A total of 70 CaWRKY genes were mapped to 12 chromosomes，whereas only
  CaWRKY70 was not mapped to any particular chromosome. Genome mapping analysis revealed that
  pepper WRKY genes were enriched on several chromosomes（1，2，3 and 7），especially on chromosome 1
  which encompasses the largest number of 10 CaWRKY genes，while chromosome 4 only contained 2
  CaWRKY genes. The pepper WRKYs from each group or subgroup were shown to share similar motif
  compositions，and CaWRKY proteins contained 132–869 amino acids and 373 in average. Our results will

• The effects of the different Pb content（0，150，450，1 350 mg · kg-1）stress on the active
  oxygen metabolism in ginger leaves were studied with a ginger（Zingiber officinale Roscoe）cultivar
  ‘Laiwu Ginger’by using the method of sewage irrigation. The results showed that with the increase of Pb
  stress level and exposure duration， productivity rate and H2O2 content increased significantly and then
  decreased under excessive Pb stress，while MDA content and electrolyte leakage rate increased
  continuously. After 40 days of Pb stress which was during the seedling stage，with the increase of Pb stress
  level，the activities of superoxide dismutase（SOD），peroxidase（POD），catalase（CAT），glutathione
  reductase（GR），ascorbate acid（APX），monodehydroascorbate reductase（MDHAR）and dehydroascorbate
  reductase（DHAR）were enhanced markedly，and the contents of reduced ascorbic acid（AsA），totalascorbic acid（AsA + DHA），reduced glutathione（GSH）and total glutathione（GSH + GSSG）were
  increased remarkably，and the ratios of AsA/DHA，GSH/GSSG were also increased significantly.
  Moreover，with ginger growth going on and the stress time increasing significantly，the antioxidant
  enzymes activities and the antioxidant substance contents were higher mostly under 150 mg · kg-1 mild Pb
  stress and inhibited under excessive Pb stress，which indicated that the AsA-GSH cycle suffered serious

• Perpetual blooming is one of the most important trait of ornamental plant，and it is the huge
  contribution of Chinese rose（diploid rose）to modern rose（tetraploid rose）breeding. However，the genetic
  basis of this trait is still largely unknown. In order to investigate the inheritance of perpetual blooming
  behavior in Rosa chinensis‘Old Blush’（OB），we developed six rose populations（OB，W，F1，F2，
  BC1OB and BC1W）derived from WOB population[interspecific diploid hybrid between OB and Rosa
  wichuriana‘Basye’s Thornless’（W）]. Perpetual blooming trait was analyzed as a major gene，and
  blooming behavior of each individual was evaluated at Flower Research Institute，Yunnan Academy of
  Agricultural Sciences（Kunming，China）from 2012 to 2015. Perpetual blooming type is absent both in a
  F1 population with 296 genotypes and a BC1W population（Rosa wichuriana‘Basye’s Thornless’as a
  backcross parent）with 150 individuals. More interesting is，a backcross population BC1OB（Rosachinensis‘Old Blush’as a backcross parent）with 300 progenies showed a 3︰1（P < 0.05）segregation ratio
  in blooming behavior（non-perpetual blooming dominant to perpetual blooming）. The results indicate that
  the inherence of perpetual blooming in rose might be regulated by double recessive loci.

• Cryptochrome 2（CRY2）was isolated from Paeonia suffruticosa by RT-PCR. The full open
  reading fragment（ORF）length of PsCRY2 encoding 633 amino acids was 1 902 bp，and the GenBank No.
  was KP982893. Sequence alignment and motif analysis showed that the deduced amino acids contained a
  PHR domain near the amino terminus and a CCT domain near the carboxy terminus. It was designated as
  PsCRY2，according to its high identity with AtCRY2 in Arabidopsis. Phylogenetic analysis showed that it
  had close relationship with Citrus sinensis. Gene expression analysis revealed that the highest expression
  levels of PsCRY2 were appeared in the bud and seed embryo of P. suffruticosa，followed by root，stem and
  leaves. The expression of PsCRY2 in the whole process of bud differentiation was high. While the
  expression of PsCRY2 was low in the early stage of bud development and quite high in the middle and latestage. The expression of PsCRY2 reached a peak in big bell-like flower-bud. The results suggested that
  PsCRY2 play an important role both in the process of bud differentiation and bud development. The
  expression patterns of PsCRY2 in the bud of‘Luoyanghong’and‘Qiufa 1’were similar，while the
  expression level of PsCRY2 in the bud of‘Qiufa 1’was significantly higher than that in the bud of
  ‘Luoyanghong’. The expression patterns of PsCRY2 in the buds with different photoperiod treatments
  were different. The expression of PsCRY2 decreased in bud sprouting and small bell-like flower bud under
  short day photoperiod，compared with that in long day photoperiod.

• The effects of various concentration of glycine betaine（GB 5，10，20 mmol · L-1）treatments
  on chilling injury and quality of peach fruits（Prunus persica Batsch‘Yuhua 2’）during cold storage were
  investigated. The results showed that various concentrations of GB treatment could reduce internal
  browning of peach fruit，wherevers 10 mmol · L-1 GB treatment had the best effect. Exogenous GB
  treatment inhibited the increase of electric conductivity and malondialdehyde（MDA）content，and
  prevented the activities of polyphenol oxidase（PPO）and peroxidase（POD）in cold-stored peach fruits.
  Moreover，10 mmol · L-1 GB treatment maintained the high level of extractable juice，total soluble solids
  content，total phenolics content and vitamin C content，and enhanced DPPH radical scavenging capability
  and reducing power in peach fruit during cold storage. These results suggested that exogenous GB
  treatment could reduce chilling injury and maintain edible quality of cold-stored peach fruits，which had
  potential application in postharvest industry.

• Dwarf mutant type was discovered during the investigation of wild pear resources in the
  Yimeng Mountain Area，and the mutant shoots were grafted on adult trees in the experimental station of
  Qingdao Agricultural University in 2009. The botanical characteristics，biological habits and the heritable
  stability of dwarf property were observed. The results showed that the mutant tree was compact with very
  short internodes of shoots，and obviously different from the general Pyrus betulaefolia. Moreover，the
  dwarf property kept stable after transfer grafting for many times on the adult trees，and virology test
  showed no obvious abnormality. Besides internodes，the villi of shoots，fruit shape，leaf，etc were obvious
  difference as comparison with P. betulaefolia and P. calleryana，and preliminary could be confirmed as a
  natural dwarf mutant type of the genus Pyrus，and named as‘PY-9’on the basis of field investigation
  number. The discovery of this resource material，provided special genetic resources for the future research
  on the pear dwarf mechanism and dwarf rootstock breeding.

• Pepper plants showing chlorotic and necrotic rings symptoms on the leaves reminiscent of
  infection by tospoviruses were found in pepper-production fields of Guangdong in 2014. The infected
  samples were detected by Dot-ELISA and RT-PCR，respectively. Negative results were obtained in the
  Dot-ELISA with monoclonal antibody of Tomato spotted wilt virus（TSWV）. This result indicated that the
  virus isolate didn’t belong to TSWV. However，an expected approximately 800 bp-fragment were obtained
  from all infected pepper samples by RT-PCR using the universal primer pair gL3637/gL4435C for
  tospoviruses. The results of gene cloning and sequence analysis showed that the fragment shared the
  highest identity at 97.5% with corresponding parts of the Guangzhou isolate of Watermelon silver mottle
  virus（WSMoV）. Phylogenic analysis showed that the virus isolate infecting pepper in Guangdong is most
  closely related to the reported isolates of WSMoV，and that they clustered in a monophyletic group.
  Therefore，the virus isolate infecting pepper in Guangdong is an isolate of WSMoV.

• Abstract ( 234 ) HTML ( 766 ) PDF (212KB) ( 766 ) 　　　

• Content change was studied on endogenous hormones and polyamine during development
  of male and female flowers of Asparagus officinalis L.‘Champion’. The results showed that GA3 content
  in female flowers was constantly higher than that in male. ABA，ZR and IAA contents decreased in female
  flowers from hermaphroditic stage to unisexual stage，while ABA，ZR and IAA contents in male flowers
  increased rapidly from hermaphroditic stage to unisexual stage. Ratios of GA3/ABA，GA3/IAA and
  GA3/ZR at hermaphroditic stage were lower in female flowers than that in male flowers，however they
  increased rapidly at unisexual stage. These results indicated that higher level of GA3 and lower level of
  ABA，IAA and ZR were related to the development of female organ and higher level of ABA，ZR and IAA
  were related to the development of male organ in asparagus. Spd，Put and Spm contents increased rapidly
  and then decreased during development of female flowers，but they remained stable in male flowers.
  Higher level of Spm，Spd and Put might be related to the development of female organ.

  Houttuynia cordata and analyse the prokaryotic expression. The cloning primers were designed based on
  the transcriptome dataset of H. cordata，one unique sequence encoding UGT75C1 was discovered. The
  sequence of UGT75C1 was cloned from H. cordata by RT-PCR. The physical and chemical properties，
  secondary structure and three-dimensional structure of the UGT75C1 protein were forecasted and
  analyzed，and its structure and function were predicted. And the different expression levels of UGT75C1
  gene in rhizome，stems，leaves，and flowers of Houttuynia cordata were analyzed by fluorescent
  quantitative PCR. And then the cloned opening reading frame of UGT75C1 gene was inserted into vectorpGEX4T-1. The recombinant plasmid pGEX4T- UGT75C1 was expressed in a prokaryotic expression
  system after they were transformed into E. coli BL21（DE3）. The fusion proteins were analyzed by
  SDS-PAGE. The cDNA contains a 1 461bp open reading frame and encodes a predicted protein of 486
  amino acids. Transmembrane regions and no signal peptide were presented in UGT75C1. The PSPG motif
  domain of glycosyltransferases was presented in UGT75C1. Relative real-time PCR analysis indicated that
  UGT75C1 showed the highest transcript abundance in the leaves，moderate level in the stems and
  rhizomes，and the lowest level in the flowers. The UGT75C1 gene was expressed in a prokaryotic
  expression system. This study cloned the UGT75C1 gene from H. cordata for the first time. It will provide
