  • In order to explore the effects of abscisic acid(ABA)on monoterpene synthesis in grape berries,this study used table grape species‘Jingxiangyu'with muscat flavor as experimental material,and soaked the clusters with 300 mg • L-1 ABA twice at one week before and during veraison. The contents of free monoterpenoids at 7,14,21,28 and 35 days after first treatment were analyzed qualitatively and quantitatively by GC–MS. The results showed that 28 kinds of monoterpenes were detected in berries,most of which accumulated during ripening. The total contents of free monoterpenoids in treated berries at maturity was 45.20% higher than that in the control,and the substance that changed most strongly was linalool. To investigate how ABA regulate monoterpenes synthesis,quantitative real-time PCR was used. The results indicated that the expression of ABA synthesis genes(VvNCED1 and VvGT)was much stronger than that of the control. The relative expression of VvβG1 increased after ABA treatment constantly. The transcriptional levels of ABA receptor VvPYL1 and signal transduction related genes VvPP2C2,VvSnRK2.1 and VvABI5 were distinctly higher than the control on 21 and 35 days after treatment respectively. The expression levels of upstream genes about monoterpene synthesis(VvDXS2,VvDXS3,VvDXR,VvGPPS)and monoterpene synthase gene VvPNLinNer was significantly higher. According to the above results,it’s suggested that exogenous ABA enhance ABA signal transduction in berries,which lead to the increase of monoterpene substrate level and facilitate monoterpene synthesis,finally improve the quality of rose flavor grapes.

  • Brazil Sour Orange(Citrus aurantium L.),Bendizao Mandarin(C. reticulata Blanco),Guihuadinanfeng mandarin(C. reticulata Blanco),Jincheng Beibei 447[C. sinensis(L.)Osbeck] and other 30 germplasms were used for mining the transcription factors related to flavonoid biosynthesis. Comparative transcriptomic analysis revealed that ERF,MYB and Dof transcription factor families are significantly involved in metabolism of flavonoids during fruit development. Correlation analysis of the expressions of CitCHS2,a key gene of flavonoids biosynthesis with the differentially expressed genes from transcriptomic analysis indicated that two R2R3-MYB family member CitMYB21(Ciclev10021699m)and CitMYB33(Ciclev10012152m)were negatively correlated to expression of CitCHS2. Phylogenic analysis revealed that these two genes belong to SG2 and SG1 subgroup of R2R3-MYBs family,respectively. The full length of CitMYB21 coding region is 804 bp and encodes 267 amino acids. The expressions of CitMYB21 were highly tissue and genotype specific,and significantly negatively correlated with the flavonoids contents. Silence of CitMYB21 resulted a significant increase of flavonoids in the leaf of transgenic plants,while transient overexpression of CitMYB21 in the peel of citrus fruit led to a significant decrease of flavonoids. Results of this study indicated that expression of CitMYB21 negatively affect the flavonoid biosynthesis in citrus,suggesting CitMYB21 may be an important transcription factor negatively regulating the biosynthesis of flavonoid.

  • Acta Horticulturae Sinica. 2023, 50(2): 265-278. DOI:10.16420/j.issn.0513-353x.2021-1008
  • Abstract ( 150 ) HTML ( 109 ) PDF (2438KB) ( 109 )    
  • Young leaves of 168 pomegranate cultivars collected from the National Forest Germplasm Resource Repository for Pomegranate,Zaozhuang City,Shandong,China were used to construct their fingerprints using SSR molecular marker technique. Based on the fingerprint information,the maximum likelihood method(LOD)was applied to hybrid screening in open-pollinated progenies of the cultivars ‘Qiuyan’and‘Huili Qingpi Ruanzi’and identification of suspected male parent. The results showed that a total of 76 alleles were amplified from 22 pairs of SSR primers in the 168 cultivar samples,including 58 polymorphic loci(accounting for 76.3%). The average number of alleles per locus(Na),effective number of alleles(Ne),observed heterozygosity(Ho)and expected heterozygosity(He)was 3.455,2.269,0.362 and 0.538,respectively. The average Shannon’s information index(I)was 0.897,the polymorphism information content(PIC)of each marker ranged from 0.330 to 0.692,with an average of 0.462. 166 pomegranate cultivar samples were distinguished by the 22 pairs of SSR primers. However,‘Damantianhongtian’and‘Xiaomantianhongtian’were not effectively distinguished,which might be synonymous. Using the allelic information,a database containing the specific fingerprint code and two-dimensional fingerprint code for each cultivar was constructed. One true hybrid Q-1 was screened from 30 offspring of open-pollinated‘Qiuyan’by using the fingerprint information. Its suspected male parent is‘Yicheng Fengchan Maya’,with the LOD value of 5.96. Six true hybrids,H-4,H-49,H-51,H-87,H-94 and H-103,were screened from 118 offspring of open-pollinated‘Huili Qingpi Ruanzi’. Their suspected male parents were‘Sichuan Huangpisuan’‘Tunisian Ruanzi’‘Mengzi Honghua Baipi’‘Sichuan Huangpisuan’‘Tunisian Ruanzi’and‘Mengzi Honghua Baipi’,respectively.

  • Acta Horticulturae Sinica. 2023, 50(2): 279-294. DOI:10.16420/j.issn.0513-353x.2021-1081
  • Abstract ( 104 ) HTML ( 43 ) PDF (5303KB) ( 43 )    
  • The fungal pathogen Fusarium oxysporum f. sp. cubense(Foc)is an important soil-borne pathogenic fungus which causes Banana Fusarium wilt. The Foc race 4(Foc 4)attacking almost all Cavendish cultivars is currently noteworthy in global banana production. In order to explore the function of DCL-like genes in Foc4,the gene-knockout mutants ΔFocDCL1,ΔFocDCL2 and ΔFocDCL1/2 were obtained by homologous recombination technique. The phenotype analysis showed the mutants showed no significant differences on vegetative growth but significant reduced in conidia production compared to the Foc4. The ΔFocDCL2 mutant increased sensitive to Congo red,and the mutant significantly reduced the size of the colony and increased the number of aerial hyphae after Congo red treatment. Next,the pathogenicity test showed that virulence of ΔFocDCL2 and ΔFocDCL1/2 were significantly reduced compared with Foc4,respectively. Furthermore,miRNA deep sequencing data showed the length distribution of the total reads,and the frequency of the 5′ first nucleotide bias of the mutants were markedly changed compared with Foc4,respectively. The miRNA could be generated depending on individual,alternative or joint DCL manners,indicating the FocDCL with overlapped and redundant function in small RNA biogenesis. In addition,DCLs-independent miRNA also be identified in the sequencing data. These results indicated that FocDCL function involved in the stress response,conidia,pathogenicity and generation of miRNAs in Foc4.

  • SONG Yanhong, CHEN Yaduo, ZHANG Xiaoyu, SONG Pan, LIU Lifeng, LI Gang, ZHAO Xia, and ZHOU Houcheng,
  • Acta Horticulturae Sinica. 2023, 50(2): 295-306. DOI:10.16420/j.issn.0513-353x.2021-1246
  • Abstract ( 110 ) HTML ( 86 ) PDF (2890KB) ( 86 )    
  • The basic helix-loop-helix(bHLH)transcription factor family of strawberry was analyzed,and the transcription factor FvbHLH130 was identified in Fragaria vesca. qRT-PCR analysis in different tissues showed that FvbHLH130 was flower-specifically expressed. Overexpression of FvbHLH130 in Arabidopsis thaliana activated flowering in transgenic lines. The full-length coding sequence of FvbHLH130 was 960 bp,encoding a 319-amino-acid protein. The prediction of conserved domain of FvbHLH130 showed that 247–297 amino acids were bHLH binding domain. The promoter of FvbHLH130 contained hormone,stress- and low temperature-response elements,which indicated FvbHLH130 might be induced by biotic and abiotic stress. The amino acids sequence of FvbHLH130 revealed up to 93.70% similarity with RcbHLH130. FvbHLH130 sequence was more closely related to Rosaceae bHLH proteins and was homologous to AtFBH4. Agrobacterium-mediated transformation of Arabidopsis thaliana showed that the FvbHLH130 overexpression lines flowered seven days earlier than the control plants,and activated the expression of flowering-related genes AtAP1,AtFT,AtFUL and AtCO. The yeast two-hybrid results showed that FvbHLH130 interacted with FvARF4 and FvARF6,which may form protein complexes in the regulation of flowering.

  • Acta Horticulturae Sinica. 2023, 50(2): 319-330. DOI:10.16420/j.issn.0513-353x.2021-1274
  • Abstract ( 61 ) HTML ( 42 ) PDF (5566KB) ( 42 )    
  • Xanthomonas campestris pv. campestris(Xcc)is the causal agent of black rot of Brassicaceae crops. The cabbage protein BobHLH34 was found to be interacted with the effector XopR through the yeast two-hybrid system. The CDS of BobHLH34 was 996 bp encoding peptides with 331 amino acids. It has a conserved domain(basic/helix1-loop-helix2). Phylogenetic tree analysis showed that bHLH34 proteins from Brassica cretica had the highest homology with BobHLH34 protein. The subcellular localization results showed that BobHLH34 was located in the nucleus. The qRT-PCR results showed that the expression of BobHLH34 was increased significantly after Xcc inoculation of cabbage leaves. The expression reached the peak at 16 h,which was 7.7 times that of the control. Vacuum infiltration of cabbage seedlings with the BobHLH34-PCVA/PCVB vector effectively down-regulated the expression of BobHLH34 gene,which resulted in susceptibility to Xcc. Taken together,BobHLH34 could positively regulate cabbage defense to black rot.

  • Acta Horticulturae Sinica. 2023, 50(2): 331-344. DOI:10.16420/j.issn.0513-353x.2021-0870
  • Abstract ( 76 ) HTML ( 42 ) PDF (1784KB) ( 42 )    
  • The regular patterns of volatile composition and relative content were analyzed with dynamic headspace bagging-adsorption and GC–MS technology in‘High Noon’of tree peony cultivar. The results showed that 34 compounds were detected and the sequences of the total relative content of the volatiles in different flowering periods was as follows:full blooming > initial flowering > decay period > blooming stage,and the highest relative content was in petals. The change during one day showed an increasing firstly and then a decrease,and reached the peak between 14:00—16:00. The linalool,2,6-Octadiene-1-diol-3,7-dimethyl,germacrene D were the main floral ingredients in the volatile of tree peony cultivar‘High Noon’. In addition, the gene Germacrene D synthase(PsGDS,GenBank accession No. MZ513465)was cloned and identified from tree peony cultivar‘High Noon’. The open reading frame of PsGDS is 1 725 bp,encoding 574 amino acids. The sequence similarity analysis between PsGDS and GDS of other species showed that the sequence similarity reached 52.6% on average,and phylogenetic analysis revealed that PsGDS has a close evolutionary relationship with woody plants,among which,grapes is the closest,and herbs is farther. The expression level in‘High Noon’is higher than other peony varieties,and the expression pattern of PsGDS showed the PsGDS was expressed the highest at the initial flowering stage of different flowering period,was also the highest at the petals of different flowering periods,and at the time period from 12:00 to 14:00 during one day. The expression pattern of PsGDS was consistent with GDS,showing a very significant positive correlation. Additionally,the analysis of subcellular localization of PsGDS revealed that PsGDS was mainly localized in the cytoplasm. These results indicated that the PsGDS was the key gene to control the volatilization of germacrene D in‘High Noon’,and play a catalytic role in the cytoplasm to catalyze the production of germacrene D.

  • Acta Horticulturae Sinica. 2023, 50(2): 345-358. DOI:10.16420/j.issn.0513-353x.2021-0921
  • Abstract ( 95 ) HTML ( 64 ) PDF (9160KB) ( 64 )    
  • With diploid and tetraploid Hedychium coronarium as test material,the developmental process of cut flowers were observed. Micrographic changes of the flower stem base,corolla tube and petals were identified by scanning and transmission electron microscopy. With the bent neck of corolla tube and initial wilting of petal as markers,the developmental process of florets was divided into six stages:bracts cracking stage,initial opening stage,blooming stage,neck bending stage,initial wilting stage,and wilting stage. Neck bending of the floret corolla tube preceded petal wilting,and the senescence of corolla tube cells arose earlier than the petal cells. The diameter of the corolla tube of the tetraploid was extremely significantly more than that of the diploid,and the ratio of the corolla tube length out of bracts to the total length of the tetraploid was significantly less than that of the diploid. During the whole vase life,the cut flowers of tetraploid were in the state of net water absorption for longer time and the basal vessel of cut flower stem were blocked more slightly than those of the diploid. The neck bending of the tetraploid floret arose later than that of the diploid,and damages of mitochondria of corolla tube and petal cells were posterior to those of the diploid. In total,neck bending of the corolla tube was the landmark for the beginning of senescence of H. coronarium floret. The significant longer longevity of the tetraploid cut flowers may be due to the thicker corolla tube and stronger support from bracts to florets,the postponed senescence of corolla tube and petal cells,and stronger water absorption and anti-blocking ability of the flower stems.

  • To characterize the function of CpLEA,a group three LEA protein gene of Chimonanthus praecox(wintersweet),CpLEA is transformed into Escherichia coli and Arabidopsis thaliana. Compared with the control strain,transgenic E. coli showed higher tolerance to low-temperature. In vitro,purified CpLEA protein could protect lactate dehydrogenase(LDH)from inactivation. Overexpression of the CpLEA gene in Arabidopsis also improved the resistance of transgenic Arabidopsis to cold and drought stresses and the degree of improved resistance was positively correlated with the accumulation of gene overexpression. The expression characteristics of CpLEA gene were further analyzed by qRT-PCR in wintersweet cutflower branch during flower-bud and display-petal stage respectively under 4 ℃ low-temperature treatment. CpLEA gene expression was found to gradually increase after low-temperature

  • Members of the AP2 subfamily were identified at the whole genome level in Chimonanthus praecox,and their expression patterns during flower development were analyzed. The expression profile of CpAP2-L11 was investigated,and 35S::CpAP2-L11 was introduced into Arabidopsis thaliana Columbia-0(Col-0)to analyze its function. A total of 20 AP2 subfamily transcription factors were identified,including five,six,and nine members from the euAP2,basalANT,and euANT groups,respectively,and all members of the euAP2 group have no miR172 binding sites. Synteny analysis revealed that 12 members form 16 pairs of duplicated genes,which were subject to purifying selection during the evolutionary process. Most AP2 subfamily members are highly expressed in April and May flower buds(FBs),with low expression during the entire or later stage of the chilling requirement(CR)accumulation;the expression level of CpAP2-L11 increased significantly in FBs initiating blooming when CR accumulation reached 570 CU. qRT-PCR analysis indicated CpAP2-L11 was highly expressed in the young fruit,outer tepals,and stamens,but a low expression level was detected in stems and leaves in C. praecox. The expression level of CpAP2-L11 was downregulated by high- or low-temperature. Ectopic expression of CpAP2-L11 in Arabidopsis showed earlier bolting time and the relative expression of FT,SOC1,LFY and AP1 genes increased significantly. CpAP2-L11 probably participates in chilling-induced dormancy breaking and blooming in winter and FBs differentiation in spring in C. praecox,also promoting flowering in ectopic overexpression Arabidopsis.

  • Abstract ( 119 ) HTML ( 113 ) PDF (4472KB) ( 113 )    
  • GRAS is a plant-specific transcription factor. In this study,78 GRAS genes were identified from the whole genome of apple(Malus × domestica)based on the conserved domain PF0351. MdGRASs encoding proteins belong to 11 subfamilies and most of them are the members of LISCL subfamily. They are located on 18 chromosomes,11 of which are located on chromosome 3. There were segmental duplication and tandem duplication events in GRAS family of apple. Ogran-specific expression profile analysis showed that,except for MdGRAS47,most of MdGRASs exhibited low transcript abundance levels in apple roots;MdGRAS20 showed higher expression level in shoots while MdGRAS18,MdGRAS55 and MdGRAS61 highly expressed in seeds. Promoter analysis indicated that all 78 MdGRASs contained light response elements,76 out of 78 MdGRASs contained stress-related elements and 37 out of 78 MdGRASs contained auxin response elements. It was confirmed that 17 MdGRASs could respond to 2,4-D with MdGRAS30 and MdGRAS61 responded to 2,4-D most significantly.

  • A new emerging banana leaf spot disease was found during a disease survey in the banana-producing area of Maoming City,Guangdong Province. The pathogen was isolated and tested for pathogenicity according to Koch's postulate,and the pathogen was identified based on morphological characteristics and sequence analyses of ITS,β-tubulin and tef1 genes. The results showed that strain MM3-2z9 could infect banana leaves and induce similar symptoms as in the field. The colony of strain MM3-2z9 on the PDA medium was white,producing obvious concentric ring patterns. The conidia were fusoid with 4-septate,three median cells versicoloured,apical cell hyaline,pyramidal,with two to four filiform apical appendages(mostly three),and basal cell with appendage single was centric and hyaline. Sequence homology analysis indicated that the ITS,β-tubulin and tef1 sequences of three single-conidial strains of MM3-2z9 were more than 98% identical to the corresponding sequences of Neopestalotiopsis musae stains. The phylogenetic tree constructed by the three fragments showed that strain MM3-2z9 was most closely related to N. musae. Therefore,strain MM3-2z9 was identified as N. musae based on morphological analysis and phylogenetic tree analysis. In addition to damaging banana(Musa AAA Cavendish)leaves,the pathogen could also quickly infect the leaves of M. × paradisiaca ABB and Musa ABB Pisang Awak‘Fenza 1’.

  • In order to explore the application prospect of matrine in the prevention and treatment of tea disease,the antifungal activity of matrine on five different Colletotrichum species including C. fioriniae,C. gloeosporioides,C. chongqingense,C. karstii and C. camelliae has been determined in this study. The results showed that matrine had significant inhibitory activity against five different Colletotrichum species. EC50(concentration for 50% of maximal effect)of the five Colletotrichum species were 5.856,6.557,3.038,7.963 and 4.397 mg • mL-1,and the antifungal activity of different species are significantly different. At low concentrations(1–8 mg • mL-1),matrine has a better control effect on both C. chongqingense and C. camelliae. With the increase of the concentration,the inhibitory rates of the five Colletotrichum species were all above 95% at 22 mg • mL-1. Microscopic examination showed that matrine had a significant effect on the mycelial and conidial growth of five Colletotrichum species. With the increase of matrine concentration,part of hyphae expanded irregularly,the number of conidia decreased and the conidia grew abnormally. Results of the biological activity of Colletotrichum species showed that the cell structure were destroyed,the cell permeability increased,and the cell oxidative stress response enhanced. The results of this study confirmed the antifungal activity of matrine against Colletotrichum species,and preliminarily revealed its antimicrobial mechanism by damaging cell membrane,which provided a theoretical basis for the prevention and control of tea brown blight disease caused by Colletotrichum.
