| 1 | Generation of two transgenic amphioxus lines using the Tol2 transposon system显示文摘Amphioxus or lancelets are regarded as a promising model animals for studying developmental mechanisms in chordates, and the evolution of vertebrate characters, because of their important phylogenetic position and their genomic and anatomical simplicity(Bertrand and Escriva, 2011; Holland and Yu, 2004). Although several recent advances have made amphioxus more tractable | Chenggang Shi Jing Huang Shixi Chen Guang Li Yiquan Wang | 2018 | Journal of Genetics and Genomics2018，45，9： | 2 |
| 2 | Salicylic acid inhibits gibberellin signaling through receptor interactions显示文摘It is well known that plants activate defense responses at the cost of growth.However,the underlying molecular mechanisms are not well understood.The phytohormones salicylic acid(SA)and gibberellin(GA)promote defense response and growth,respectively.Here we show that SA inhibits GA signaling to repress plant growth.We found that the SA receptor NPR1 interacts with the GA receptor GID1.Further biochemical studies revealed that NPR1 functions as an adaptor of ubiquitin E3 ligase to promote the polyubiquitination and degradation of GID1,which enhances the stability of DELLA proteins,the negative regulators of GA signaling.Genetic analysis suggested that NPR1,GID1,and DELLA proteins are all required for the SA-mediated growth inhibition.Collectively,our study not only uncovers a novel regulatory mechanism of growth-defense trade-off but also reveals the interaction of hormone receptors as a new mode of hormonal crosstalk. | Xiaodong Yu Xiaoyu Cui Chong Wu Shixi Shi Shunping Yan | 2022 | Molecular Plant2022，15，11： | 0 |
| 3 | The shikimate pathway regulates programmed cell death显示文摘Programmed cell death(PCD)is essential for both plant development and stress responses including immunity.However,how plants control PCD is not well-understood.The shikimate pathway is one of the most important metabolic pathways in plants,but its relationship to PCD is unknown.Here,we show that the shikimate pathway promotes PCD in Arabidopsis.We identify a photoperiod-dependent lesion-mimic mutant named Lesion in short-day(lis),which forms spontaneous lesions in short-day conditions.Mapbased cloning and whole-genome resequencing reveal that LIS encodes MEE32,a bifunctional enzyme in the shikimate pathway.Metabolic analysis shows that the level of shikimate is dramatically increased in lis.Through genetic screenings,three suppressors of lis(slis)are identified and the causal genes are cloned.SLISes encode proteins upstream of MEE32 in the shikimate pathway.Furthermore,exogenous shikimate treatment causes PCD.Our study uncovers a link between the shikimate pathway and PCD,and suggests that the accumulation of shikimate is an alternative explanation for the action of glyphosate,the most successful herbicide. | Xuerui Lu Shixi Shi Chong Wu Xueao Zheng Chenkun Yang Jie Luo Shunping Yan | 2022 | Journal of Genetics and Genomics2022，49，10： | 0 |
