| 1 | Putative Phosphatase UvPsr1 Is Required for Mycelial Growth, Conidiation, Stress Response and Pathogenicity in Ustilaginonidea virens显示文摘Ustilaginoidea virens is the causal agent of rice false smut,which can be a highly destructive disease of rice.The plasma membrane phosphatase Psr1 proteins,which act as a regulator of the salinity stress response in yeast,are widely distributed across fungi,but their functional characterization is sketchy.In this study,we characterized the functions of Psr1 protein,UvPsr1,in U.virens.Analyses of the AUvpsr1 and its complementation strain showed that UvPsr1 is required for normal mycelial growth,conidiation and tolerance to oxidative,osmotic and cell wall stresses.When rice panicles were inoculated with the AUvpsr1 strains,no symptoms of false smut disease developed,showing that UvPSR1 also contributes to the pathogenicity of the fungus.The deletion mutant of UvPSR1 also appeared to produce a smaller titer of toxic compounds able to inhibit elongation of the germinated seeds.In conclusion,our results indicated that UvPsr1 is a new pathogenic factor of U.virens. | Xiong Meng Meng Shuai Qiu Jiehua Shi Huanbin Shen Xiangling Kou Yanjun | 2020 | Rice science2020，27，6： | 2 |
| 2 | Regulatory network established by transcription factors transmits drought stress signals in plant显示文摘Plants are sessile organisms that evolve with a flexible signal transduction system in order to rapidly respond to environmental changes.Drought,a common abiotic stress,affects multiple plant developmental processes especially growth.In response to drought stress,an intricate hierarchical regulatory network is established in plant to survive from the extreme environment.The transcriptional regulation carried out by transcription factors(TFs)is the most important step for the establishment of the network.In this review,we summarized almost all the TFs that have been reported to participate in drought tolerance(DT)in plant.Totally 466 TFs from 86 plant species that mostly belong to 11 families are collected here.This demonstrates that TFs in these 11 families are the main transcriptional regulators of plant DT.The regulatory network is built by direct protein-protein interaction or mutual regulation of TFs.TFs receive upstream signals possibly via post-transcriptional regulation and output signals to downstream targets via direct binding to their promoters to regulate gene expression. | Yongfeng Hu Xiaoliang Chen Xiangling Shen | 2022 | Stress Biology2022，2，1： | 0 |
