| 1 | Overexpression of GhPFN2 enhances protection against Verticillium dahliae invasion in cotton显示文摘Growing evidence indicates that actin cytoskeleton is involved in plant innate immune responses,but the functional mechanism remains largely unknown.Here,we investigated the behavior of a cotton profilin gene(GhPFN2) in response to Verticillium dahliae invasion,and evaluated its contribution to plant defense against this soil-borne fungal pathogen.GhPFN2 expression was up-regulated when cotton root was inoculated with V.dahliae,and the actin architecture was reorganized in the infected root cells,with a clear increase in the density of filamentous actin and the extent of actin bundling.Compared to the wild type,GhPFN2-overexpressing cotton plants showed enhanced protection against V.dahliae infection and the actin cytoskeleton organization in root epidermal cells was clearly altered,which phenocopied that of the wild-type(WT) root cells challenged with V.dahliae.These results provide a solid line of evidence showing that actin cytoskeleton reorganization involving GhPFN2 is important for defense against V.dahliae infection. | Wenyan Wang Yongduo Sun Libo Han Lei Su Ouixian Xia Haiyun Wang | 2017 | Science China(Life Sciences)2017，60，8： | 4 |

| 3 | The two domains of cotton WLIM1a protein are functionally divergent显示文摘Our previous study demonstrated that WLIM1a has dual roles in fiber elongation and secondary cell wall synthesis in upland cotton,and the protein acts either as an actin-binding protein or as a transcription factor.Because WLIM1a consists of two different LIM domains,it is possible that these elements contribute differentially to the dual functions of the protein.In this study,we dissected the two LIM domains and characterized their biochemical functions.By using red fluorescent protein(RFP)fusion,co-sedimentation,and DNA binding methods,we found that the two domains of WLIM1a,domain1(D1)and domain2(D2),possessed different biochemical properties.While D1 contributed primarily to the actin filament-bundling activity of WLIM1a,D2 contributed to the DNA-binding activity of the protein;both D1 and D2 relied on a linker sequence for their activities.In addition,we found that WLIM1a and its two LIM domains form dimers in vitro.These results may lead to a better understanding of the molecular mechanisms of dual functions of WLIM1a during cotton fiber development. | Libo Han Yuanbao Li Yongduo Sun Haiyun Wang Zhaosheng Kong Guixian Xia | 2016 | Science China(Life Sciences)2016，59，2： | 0 |
