This article summarized a family of conserved DHHC proteins with palmitoyltransferase activity that had been discovered from plants to mammals. The method of protein palmitoylation was so concluded. The paper also introduced the research methods of protein palmitoylation, the prediction methods of palmitoylation sites (CSS-Palm, NBA-Palm, TermiNator2), radioactive labeling (radiolabeling with 3H palmitate or 125I-IC16 palmitate) and non-radioactive labeling (chemical labeling and mass spectrometry) to detect palmitoylated proteins. Next, techniques to inhibit protein palmitoylation were described. These included site specific mutagenesis, and treatment of cells with inhibitors of protein palmitoylation, including 2-bromopalmitate, cerulenin, and tunicamycin. Based on the authors’ research directions, the response of protein palmitoylation in plant stress and the application prospect of plant stress resistance were summarized and prospected.

The results showed that leaf SPAD values of mangrove plants had significant differences among plots and even in the same plant. SPAD values from 15 sample plots were grouped into 7 groups by Duncan’s multiple range test of one-way ANOVA, meanwhile, SPAD values had also extremely significant interspecific differences. SPAD value of Kandelia obvolata was highest (70.4), those of Rhizophora stylosa, Bruguiera gymnorrhiza, Avicennia marina and Aegiceras corniculatum were 65.9, 62.9, 51.9 and 48.6 respectively, and the SPAD means of 5 species was 60.5. Best linear unbiased prediction was used to estimate of random effects, and the results showed that effect of species factor was very significant (P<0.01) and stronger than effect of plot factor, which meant mangrove species was a main factor influencing leaf SPAD value and indicated different site conditions had also effects on it. The correlation analysis showed that SPAD values in 5 species of mangrove plants had significant positive correlation with their basal diameter and tree height.

Floral Biology and Pollen Germination of Magnolia championii LIU Kun-liang,WANG Ya-ling,ZHANG Shou-zhou Subtropical Plant Science    2013, 42 (04): 293-296.   DOI: 10.3969/j.issn.1009-7791.2013.04.003 Abstract （2177）      PDF（pc） （523KB）（797）       Knowledge map    Save The structure and floral biology were studied in this paper, among which the pollen germination was observed. When all bracts split and fall, stigmas were usually receptive while the flower was still closed. Once the outer tepals were open, the inter-tepals were enclosed so closely that few insects could get inside the flower for pollination. The blooming period were from June to July when it was rainy season in Shenzhen. Few blossoms at the same time could not attract enough pollinators. All of above reason led to the low seed set.

Effects of PEG on Germination of Bauhinia Pollens WANG Xiao-liang Subtropical Plant Science    2014, 43 (02): 168-169.   DOI: 10.3969/j.issn.1009-7791.2014.02.018 Abstract （2171）      PDF（pc） （493KB）（495）       Knowledge map    Save The effects of different concentration of PEG on Bauhinia (Cercis chinensis) pollen germination were studied in this paper. The results showed that 5～30 g·L-1 PEG promoted the Bauhinia pollen germination rate and tube length, the pollen germination rate and tube length in the treatment of 20 g·L-1 concentration were both significantly higher than the other treatments.

Effect of Light and Temperature on Seed Germination of Clematis ranunculoides Subtropical Plant Science    2013, 42 (01): 43-45.   Abstract （2168）      PDF（pc） （320KB）（746）       Knowledge map    Save In order to study the effect of light and temperature on seed germination of Clematis ranunculoides and its basic biological characteristics, its wild plant seeds were collected, moreover, the seed’s appearance was observed, and the thousand-seed weight was detected. The laboratory test method was used to determine the germination rate and potentiality under different conditions of light and temperature. The results showed that the thousand-seed weight of C. ranunculoides was 1.6624±0.0006 g. The optimal temperature for the seed germination was 20~25 ℃, and at this temperature, the seed begin to germinate in 8 days after seeding, and the germination procedure finished in 3~4 weeks, with the germination rate of 90.33%. Both higher and lower temperature could cause the decrease of germination rate, while light and dark did not influence significantly on the germination rate of C. ranunculoides seed.

Effect of Activated Carbon on the Seed Germination and Seedling Growth of Wheat Variety Yannong 19 YIN Xiang-bo,LIU Chen,WANG Zhi-li,MA Yun-fei Subtropical Plant Science    2013, 42 (02): 124-126.   DOI: 10.3969/j.issn.1009-7791.2013.02.008 Abstract （2162）      PDF（pc） （296KB）（703）       Knowledge map    Save With garden soil for basic training materials, the germination and seedlings growth of wheat variety Yannong 19 were investigated under the conditions of different content of activated carbon. The activated carbon 0.0 (CK), 0.5, 1.0, 1.5, 2.0 g mixed evenly into 150 g of garden soil and were used to culture the seed of wheat variety Yannong 19. After germination, the wheat germination rate, seedling traits indicators of height, root length, fresh weight, and soluble sugar and chlorophyll content were measured. The results showed that within the experimental range, with the increase of the application rate of activated carbon, the wheat root length, soluble sugar content and chlorophyll content were rising firstly and then falling, but seedling height and germination rate continued to increase. So the appropriate activated carbon mixed in garden soil can effectively promote the growth of wheat. Reference | Related Articles | Metrics | Comments（0）
