| 1 | A Genomic Variation Map Provides Insights into the Genetic Basis of Spring Chinese Cabbage (Brassica rapa ssp.pekinensis)Selection显示文摘Chinese cabbage is the most consumed leafy crop in East Asian countries.However,premature bolting induced by continuous low temperatures severely decreases the yield and quality of the Chinese cabbage, and therefore restricts its planting season and geographic distribution.In the past 40years,spring Chinese cabbage with strong winterness has been selected to meet the market demand.Here,we report a genome variation map of Chinese cabbage generated from the resequencing data of 194 geographically diverse accessions of three ecotypes.In-depth analyses of the selection sweeps and genome-wide patterns revealed that spring Chinese cabbage was selected from a specific population of autumn Chinese cabbage around the area of Shandong peninsula in northern China.We identified 23 genomic loci that underwent intensive selection,and further demonstrated by gene expression and haplotype analyses that the incorporation of elite alleles of VERNALISATION INSENTIVE 3.1(BrVIN3.1)and FLOWER LOCUS C 1(BrFLC1)is a determinant genetic source of variation during selection.Moreover,we showed that the quantitative response of BrVIN3.1 to cold due to the sequence variations in the cis elements of the BrVlN3.1 promoter significantly contributes to bolting-time variation in Chinese cabbage.Collectively, our study provides valuable insights into the genetic basis of spring Chinese cabbage selection and will facilitate the breeding of bolting-resistant Varieties by molecular-marker-assisted selection,transgenic or gene editingapproaches. | Tongbing Su Weihong Wang Peirong Li Bin Zhang Pan Li Xiaoyun Xin Honghe Sun Yangjun Yu Deshuang Zhang Xiuyun Zhao Changlong Wen Gang Zhou Yuntong Wang Hongkun Zheng Shuancang Yu Fenglan Zhang | 2018 | Molecular Plant2018，11，11： | 6 |

| 3 | Self-assembly of homopolymer of PAA-NH_4显示文摘Self-assembly of homo-polymers has rarely been reported. Herein, PAA-NH_4 assemblies varying from nanospheres to large particles and yolk-shell vesicles were obtained by adding different amount of HCI solution into the dispersion of PAA-NH_4 in ethanol. The changes of zeta potentials, pH value and microstructure of the PAA-NH_4 assemblies were characterized, and the influences of molecular weight and different alcohols on the assembly morphologies were studied. A possible assembly mechanism based on the solubility and electrostatic interaction was proposed. Our study offered an interesting example of homo-polymer assembly and may extend the practical application due to the simple polymers used. | Tongbing Sun Xiaoli Yang Caizhen Zhu Ning Zhao Haixia Dong Jian Xu | 2019 | Chinese Chemical Letters2019，30，2： | 0 |
