ENO2是一种多功能基因，编码可选择性翻译的两种蛋白（ENO2和MBP-1）。ENO2基因缺失导致植物生长和生殖发育缺陷，植株变小，花粉萌发率下降，角果变短。以前的研究主要集中在ENO2基因的整体功能，尚未见将它的两种选择性翻译蛋白ENO2和MBP-1区分开进行比较研究的报道，其在植物生长、生殖发育及其调控通路中的作用仍不清楚。本项目拟在前期研究基础上，从多层次水平（表型、转录组、蛋白质组）研究ENO2/MBP-1及其编码序列（ENO2-only/MBP-1）在植物生长、生殖发育和盐胁迫响应中的功能及其调控机制，并揭示MBP-1转录调控的靶基因及入核机理，为深入认识植物在逆境胁迫响应的调控网络和分子机制提供新的线索，为作物育种提供抗逆候选基因。

ENO2 is a multifunctional gene encoding two proteins (ENO2 and MBP-1) that can be selectively translated in Arabidopsis thaliana. It has been studied that the absence of ENO2 gene causes the defective growth and reproduction of plant, i.e., smaller plant, reduced germination rate of pollen, and shorter silique. Previous studies focused on the overall functions of ENO2 gene. However, the two selective translated proteins of ENO2 gene, ENO2 and MBP-1, are not comparatively studied. In particular, the functions of ENO2 and MBP-1 in growth, reproductive development, and their regulatory pathways are unclear. On the basis of previous researches, this project will research the functions of ENO2/MBP-1 and its coding sequence (ENO2-only/MBP-1) in plant growth, reproductive development and response to salt stress, including the related regulatory mechanism, from multi-levels (i.e., phenotype, transcriptome, and proteome). Results from this project will also reveal the target genes regulated by MBP-1 and the mechanism of entering into the nuclear , and provide a new clue to the regulatory network and molecular mechanism of stress response in plants, and provide candidate gene for crop breeding.
