| 1 | DIW1 encoding a cladeⅠPP2C phosphatase negatively regulates drought tolerance by de-phosphorylating TaSnRK1.1 in wheat显示文摘Drought seriously impacts wheat production(Triticum aestivum L.),while the exploitation and utilization of genes for drought tolerance are insufficient.Leaf wilting is a direct reflection of drought tolerance in plants.Clade A PP2Cs are abscisic acid(ABA)co-receptors playing vital roles in the ABA signaling pathway,regulating drought response.However,the roles of other clade PP2Cs in drought tolerance,especially in wheat,remain largely unknown.Here,we identified a gain-of-function drought-induced wilting 1(DIW1)gene from the wheat Aikang 58 mutant library by map-based cloning,which encodes a cladeⅠprotein phosphatase 2C(TaPP2C158)with enhanced protein phosphatase activity.Phenotypic analysis of overexpression and CRISPR/Cas9 mutant lines demonstrated that DIW1/TaPP2C158 is a negative regulator responsible for drought resistance.We found that TaPP2C158 directly interacts with TaSnRK1.1 and de-phosphorylates it,thus inactivating the TaSnRK1.1–Ta AREB3 pathway.TaPP2C158 protein phosphatase activity is negatively correlated with ABA signaling.Association analysis suggested that C-terminal variation of TaPP2C158 changing protein phosphatase activity is highly correlated with the canopy temperature,and seedling survival rate under drought stress.Our data suggest that the favorable allele with lower phosphatase activity of TaPP2C158 has been positively selected in Chinese breeding history.This work benefits us in understanding the molecular mechanism of wheat drought tolerance,and provides elite genetic resources and molecular markers for improving wheat drought tolerance. | Jingyi Wang Chaonan Li Long Li Lifeng Gao Ge Hu Yanfei Zhang Matthew P.Reynolds Xueyong Zhang Jizeng Jia Xinguo Mao Ruilian Jing | 2023 | Journal of Integrative Plant Biology2023，65，8： | 1 |

| 10 | Resignation of officials as independent directors and firm performance显示文摘In 2013,the Chinese government implemented Rule No.18,which suspended the directorships of incumbent government officials and precluded those who retired within the past three years from serving as independent directors for listed firms.The surprise implementation of Rule No.18 triggered a wave of resignations among official independent directors(OIDs).The event provided a unique opportunity to examine the impacts of the political connections of board members on firm performance.We applied a difference-in-difference technique to empirically investigate the effect of OID resignations on firm performance from the perspectives of resource dependence theory and social capital theory.The results indicate that the resignation of OIDs had a significantly negative effect on firm performance,as measured by Tobin's 0 and firm leverage.This also confirmed the importance of independent directors'political connection on firm performance,as discovered in prior research.However,this influence varied across OIDs'heterogeneity,external environment and firm ownership.The results indicate that political connections may not be necessary channels for firms to achieve success. | Ting Ren Youzhi Xiao Xinguo Yu Hongyan Yang Jianmei Ge | 2020 | Frontiers of Business Research in China2020，14，4： | 0 |
