| 1 | TaBZR1 enhances wheat salt tolerance via promoting ABA biosynthesis and ROS scavenging显示文摘Brassinosteroids(BRs)are vital plant steroid hormones involved in numerous aspects of plant life including growth,development,and responses to various stresses.However,the underlying mechanisms of how BR regulates abiotic stress responses in wheat(Triticum aestivum L.)remain to be elucidated.Here,we find that BR signal core transcription factor BRASSINAZOLE-RESISTANT1(TaBZR1)is significantly up-regulated by salt treatment.Overexpression of Tabzr1-1D(a gain-of-function TaBZR1 mutant protein)improves wheat salt tolerance.Furthermore,we show that TaBZR1 binds directly to the G-box motif in the promoter of ABA biosynthesis gene TaNCED3 to activate its expression and promotes ABA accumulation.Moreover,TaBZR1 associates with the promoters of ROS-scavenging genes TaGPX2 and TaGPX3 to activate their expression.Taken together,our results elucidate that TaBZR1 improves salt-stress tolerance by activating some genes involved in the biosynthesis of ABA and ROS scavenging in wheat,which gives us a new strategy to improve the salt tolerance of wheat. | Ruizhen Yang Ziyi Yang Meng Xing Yexing Jing Yunwei Zhang Kewei Zhang Yun Zhou Huixian Zhao Weihua Qiao Jiaqiang Sun | 2023 | Journal of Genetics and Genomics2023，50，11： | 0 |
| 2 | Continuity of the robustness of contextuality of empirical models显示文摘Recently, the robustness of contextuality(RoC) of an empirical model was discussed in [Sci. China-Phys. Mech. Astron. 59,640303(2016)], many important properties of the RoC have been proved except for its boundedness and continuity. The aim of this paper is to find an upper bound for the RoC over all of empirical models and prove that the RoC is a continuous function on the set of all empirical models. Lastly, a relationship between the RoC and the extent of violating the noncontextual inequalities is established for an n-cycle contextual box. This relationship implies that the RoC can be used to quantify the contextuality of n-cycle boxes. | HuiXian Meng HuaiXin Cao WenHua Wang Liang Chen Yajing Fan | 2016 | Science China(Physics,Mechanics & Astronomy)2016，59，10： | 0 |
| 3 | The genetic basis of the leafy seadragon's unique camouflage morphology and avenues for its efficient conservation derived from habitat modeling显示文摘The leafy seadragon certainly is among evolution’s most“beautiful and wonderful”species aptly named for its extraordinary camouflage mimicking its coastal seaweed habitat.However,limited information is known about the genetic basis of its phenotypes and conspicuous camouflage.Here,we revealed genomic signatures of rapid evolution and positive selection in core genes related to its camouflage,which allowed us to predict population dynamics for this species.Comparative genomic analysis revealed that seadragons have the smallest olfactory repertoires among all ray-finned fishes,suggesting adaptations to the highly specialized habitat.Other positively selected and rapidly evolving genes that serve in bone development and coloration are highly expressed in the leaf-like appendages,supporting a recent adaptive shift in camouflage appendage formation.Knock-out of bmp6 results in dysplastic intermuscular bones with a significantly reduced number in zebrafish,implying its important function in bone formation.Global climate change-induced loss of seagrass beds now severely threatens the continued existence of this enigmatic species.The leafy seadragon has a historically small population size likely due to its specific habitat requirements that further exacerbate its vulnerability to climate change.Therefore,taking climate change-induced range shifts into account while developing future protection strategies. | Meng Qu Yingyi Zhang Zexia Gao Zhixin Zhang Yali Liu Shiming Wan Xin Wang Haiyan Yu Huixian Zhang Yuhong Liu Ralf Schneider Axel Meyer Qiang Lin | 2023 | Science China(Life Sciences)2023，66，6： | 0 |
| 4 | The robustness of contextuality and the contextuality cost of empirical models显示文摘In this paper, we introduce and discuss the robustness of contextuality(Ro C) R_C(e) and the contextuality cost C(e) of an empirical model e. The following properties of them are proved.(i) An empirical model e is contextual if and only if R_C(e) > 0;(ii) the Ro C function R_C is convex, lower semi-continuous and un-increasing under an affine mapping on the set E M of all empirical models;(iii) e is non-contextual if and only if C(e) = 0;(iv) e is contextual if and only if C(e) > 0;(v) e is strongly contextual if and only if C(e) = 1. Also, a relationship between RC(e) and C(e) is obtained. Lastly, the Ro C of three empirical models is computed and compared. Especially, the Ro C of the PR boxes is obtained and the supremum 0.5 is found for the Ro C of all no-signaling type(2, 2, 2) empirical models. | HuiXian Meng HuaiXin Cao WenHua Wang | 2016 | Science China(Physics,Mechanics & Astronomy)2016，59，4： | 0 |
