• Induction of disease resistance is one of the important strategies of biological control on fruit postharvest decay. The mandarin（Citrus reticulata Blancdo‘Shiyueju’）fruit were inoculated with Penicillium digitatum after vacuum infiltration of Benzothiadiazole（BTH）. Results showed that the expression of CR-CT1 and CR-BG3 substantially increased 12 h after BTH treatment. The morbidity and lesion area of green mold in mandarins，and the in vivo disease incidences of the fruit were signicantly reduced by different concentrations of BTH. BTH treatment induced the activities of CT，GUN，PAL，PPO，POD，and evoked the increase of H2O2 content. The results suggested that strong expression of CR-CT1 and CR-BG3，enhanced activities of several defense enzymes and H2O2 content are all involved in the induction of disease resistance by BTH treatment in mandarin fruit.

• In order to evaluate genetic diversity and relationship of yellow flesh peach germplasm，116 yellow flesh peach varieties，as well as other 19 peach germplasms，were used as plant material. A total of 206 alleles were amplified when screened by 28 SSR primers（26 of them distributed on eight linkage groups on Prunus reference map）. Among all the alleles amplified，159 showed polymorphic with a percentage of polymorphic bands（PPB）of 76.56%. For yellow flesh peaches，two main groups were formed in dendrogram at a similarity coefficient of 0.82，when clustered by NTSYS using UPGMA method. Bred varieties from America，Europe and Asia were clustered into one group（Ⅰ），and local varieties from China were clustered into another group（Ⅱ），except‘Xi’an Xingrangtao’and‘Tianjin Huangrou’，which were clustered into bred group. When similarity coefficient was 0.87，bred varieties（Ⅰ）were divided into 8 subgroups. Bred varieties from America were distributed in all the 8 subgroups，and bred varieties from Europe were distributed in three subgroups（Ⅰ-2，Ⅰ-3，andⅠ-4），while bred varieties from Asia were only distributed in two subgroups（Ⅰ-3 andⅠ-4）. Varieties with the same parents were closely clustered，and genetic relationship of bred varieties matched well with pedigree in groupⅠ. When similarity coefficient was 0.87，Chinese local yellow peach varieties were divided into 7 subgroups. Local yellow peaches from southwest China were mainly distributed in subgroup Ⅱ-1 and Ⅱ-5，and those from northwest China were mainly distributed in subgroup Ⅱ-2，Ⅱ-4 and Ⅱ-7. For variety population genetic relationship，bred variety from America was the nearest population to that of Asia，followed by that of Europe. Chinese local yellow peach was far from bred varieties on population dendrogram.

• The regulative sequence（1 711 bp）of chalcone synthase gene promoter（CHSP）from Ginkgo biloba L. was cloned by genomic walking. In silico analysis suggested that the sequence contained several typical cis-acting elements，including UV/blue light responsive elements，phytohormone responsive elements，fungal elicitor responsive elements，MYB binding site，TATA-box and CAAT-box. A 1 402 bp promoter sequence upstream 5′ of translation start site of GbCHS was cloned and designated as GbCHSP，respectively. pBI121 + CHSP and pBI121-35S were constructed and transformed into tobaccos by LBA4404. These results showed that pBI121 and pBI121 + CHSP both could drive the transient expression of GUS in tobaccos and pBI121 + CHSP expressed differentially in root，stem and leaf tissues of tobacco. These results will be help to understand the transcriptional regulatory mechanism on GbCHS expression and flavonoids accumulation.

• To investigate the function of the MaWRKY1 gene，a transcription factor previously cloned from banana fruit，the polyclonal antibody of MaWRKY1 was prepared. The recombinant plasmid pET-MaWRKY1 was constructed with 699 bp segments started from the 168 amino acid to the 400 amino acid including the two conserved motif WRKYGQK and an about 26 kD expressed His-MaWRKY1 fusion protein was identified by SDS-PAGE following the expression of the recombinant His-MaWRKY1 fusion protein in E.coli BL21（DE3）cells with high efficiency. About 0.5 mg • mL-1 fusion protein was obtained after puified by Ni-NTA agarosecolumn，separated by SDS-PAGE，excised from the gel and electroeluted，then the purified fusion protein was used as antigen to prepare polyclonal antiserum in rabbits. After the fifth injection of antigen，the antiserum was obtained and further purified with method of immuno-precipitation. Indirect ELISA test and the western blot analysis showed that the obtained anti-MaWRKY1 polyclonal antibody have good sensitivity and high specificity with a titer of 1︰160 000. Furthermore，western blot assay revealed that a 26 kD peptide was specifically detected in the total proteins of different banana tissues with anti-MaWRKY1 polyclonal antibody，indicating that the antibody could react to the total proteins expressed in banana specifically. In addition，low temperature could induce the expression of MaWRKY1 protein in banana fruit，suggesting that the expression of MaWRKY1 protein in banana fruit was likely to be involved in regulating the chilling-tolerance of fruit.

• The effects of Ca2+ on the changes of soluble protein，malondialdehyde（MDA）contents，superoxideanion（）production rate，superoxide dismutase（SOD），peroxidase（POD）and catalase（CAT）activities in cucumber（Cucumis sativus L.‘Jinchun 2’）seedlings under 50 mmol • L-1 NaCl salt treament was studied. The results showed that the contents of soluble proteins and MDA， production rate，antioxidant enzyme activities were higher in salt stress than control；In salt + Ca2+ treatment，soluble proteins content，SOD，POD and CAT activities increased，while MDA content and  production rate decreased. Under salt stress and salt + Ca2+，the MDA content， production rate raised，while soluble proteins content，SOD，POD and CAT activities declined. The results indicated that Ca2+ could raise the activities of antioxidant enzymes and decrease the membrane lipid peroxidation for cucumber seedlings，which could alleviate the damage of salt stress and improve the salt stress adaptability of cucumber seedlings.

• We observed the floral development of anemone and non-anemone type chrysanthemum as well as the histological structures of different types of petals by paraffin section method. The results indicated that the flower bud differentiation of chrysanthemum included two stages such as the inflorescence and floret differentiation. The difference of floral development between anemone and non-anemone type chrysanthemum occurred in the stage of the elongation of floret corolla. The histological structure of disk floret in the anemone type chrysanthemum plays similarities with that of the ray floret not only at their developmental stage but also at the mature stage. They all consist of multiple cell layers including upper and lower epidermal cell layers and internal loose mesophyll cells. Nevertheless，the disk floret of the non-anemone type chrysanthemum just has the petal layout of upper and lower epidermal cell layers. In the development of the disk floret in anemone type chrysanthemum，the exuberant division activity of the internal cells of the petal and the well developed vascular tissues are probably the important reasons for the formation of the anemone.

• Pollinium morphology of five most common cultivated orchid genera（Orchidaceae）were examined with SEM（scanning electron microscopy）. The results showed that thousands up to ten thousands of pollen grainsare aggregated into distinct pollinia. The pollinia presented diversity in shape，from near pear-shaped，near ovate，to oblong oval. The figures of pollen grains are irregular. The tetrad pollen grains were only found in species of Cymbidium ensifolium. Except C. faberi，there are not obvious sticky semiliquid substance covered the pollen grains. The pollinium of the speces studied can be divided into four types based on the sculpturing of exine. There are psilate，near psilate or very obscurely fossete，rough and fossulate or foveolate. There are no aperture on the exinous lay of pollen grains. The pollinium size and sculpturing of exine showed obviously different among the genera and species in this study. Within the genus Cymbidium，the sculpturing of pollinium differed on the species level but not obviously on the cultivated variation level.

• The lotus（Nelumbo nucifera Gaertn）seed defensin gene was identified from the lotus cDNA library of middle development stage seed embryo. The 561 bp full length cDNA have a 234 bp open reading frame which encoding a 77 amino acid peptide and was designated as NnDefensin. The amino acid sequence of NnDefensin showed relatively high match with other plant defensin genes and phylogeny analysis showed that NnDefensin have close relationship with defensin from Oryza sativa japonica group，defensin precursor from Triticum aestivum and defensin from Plantago major. NnDefensin have a strictly conserved γ- thionin domain of eight cysteine which is characteristic in plant defencin. Specific primers containing restriction enzyme site of SmaⅠ and SacⅠ was used to amplify the sequence of NnDefensin by polymerase chain reaction（PCR）. The binary expression vector pBI121 and vector pAhOleo17.8︰GUS which containing a seed specific promoter were digested by the corresponding restricted enzymes respectively，and linked with the NnDefinsin fragment directionally. The resulting construction was obtained and named pBI121-NnDef in which NnDefensin was driven by 35S promoter，and pAhOleo-NnDef in which NnDefensin was driven by seed specific promoter AhOleo17.8 from peanut（Arachis hypogaea L.）. The vectors could be transformed into plants mediated by Agrobacterium tumefaciens for the following up research such as gene functional identification and gene transformation for pathogen resistant improvement in transgenic plants and seeds.

• The effects of cold stress on growth index，freezing injury index and chlorophyll fluorescence parameters in seven different genotype cauliflowers with different or same maturity were studied. The changes of chlorophyll fluorescence parameters in different genotype cauliflowers with same maturity under freezing injury stress were also examined. The correlations among growth，cold tolerance and chlorophyll fluorescence parameters were analyzed in cauliflower varieties with different or same maturity. The results showed that there were significant differences among the varieties with different maturity in freezing injury index and minimal fluorescence（Fo），and there were significant differences among the varieties with the same and different maturity in head weight，vegetative mass weight，SPAD value and conversion efficiency of primary light energy（Fv/Fm）. Significant differences existed among the varieties with same maturity under freezing injury stress. Correlation analysis of growth index，freezing injury index and chlorophyll fluorescence parameters in different genotype varieties showed that freezing injury index which directly reflects cold tolerance were negatively correlated with SPAD and Fv/Fm. Head weight and vegetative mass weight which indirectly but externally reflects cold tolerance，were positively correlated with Fv/Fm in varieties with both same and different maturity，and positively correlated with SPAD only in varieties with different maturity. In conclusion，conversion efficiency of primary light energy closely related to cold tolerance，Fv/Fm could be used as index of cold tolerance identification in cauliflowers with both same and different maturity.
