| 1 | ζ-Carotene Isomerase Suppresses Tillering in Rice through the Coordinated Biosynthesis of Strigolactone and Abscisic Acid显示文摘Rice tillering is an important agronomic trait affecting grain yield.Here,we identified a high-tillering mutant tillering20(t20),which could be restored to the wild type by treatment with the strigolactone(SL)analog rac-GR24.T20 encodes a chloroplast ζ-carotene isomerase(Z-ISO),which is involved in the biosynthesis of ca-rotenoids and their metabolites,SL and abscisic acid(ABA).The t20 mutant has reduced SL and ABA,raising the question of how SL and ABA biosynthesis is coordinated,and whether they have overlapping functions in tillering.We discovered that rac-GR24 stimulated T20 expression and enhanced all-trans-p-carotene biosynthesis.Importantly,rac-GR24 also stimulated expression of Oryza sativa 9-CIS-EPOXY-CAROTENOID DIOXYGENASE 1(OsNCED1)through induction of Oryza sativa HOMEOBOX12(0sHOX12),promoting ABA biosynthesis in shoot base.On the other hand,ABA treatment significantly repressed SL biosynthesis and the ABA biosynthetic mutants displayed elevated SL biosynthesis.ABA treatment reduced the number of basal tillers in both t20 and wild-type plants.Furthermore,while ABA-deficient mu-tants aba1 and aba2 had the same number of basal tillers as wild type,they had more unproductive upper tillers at maturity.This work demonstrates complex interactions in the biosynthesis of carotenoid,SLs and ABA,and reveals a role for ABA in the regulation of rice tillering. | Xue Liu Qingliang Hu Jijun Yan Kai Sun Yan Liang Meiru Jia Xiangbing Meng Shuang Fang Yiqin Wang Yanhui Jing Guifu Liu Dianxing Wu Chengcai Chu Steven M.Smith Jinfang Chu Yonghong Wang Jiayang Li Bing Wang | 2020 | Molecular Plant2020，13，12： | 11 |
| 2 | CRISPR/Cas9-introduced single and multiple mutagenesis in strawberry显示文摘CRISPR/Cas9-mediated genome editing is a powerful tool for life science research.Recently,strawberry (Fragaria × ananassa),an important horticultural crop,has emerged as a model organism for investigating the regulatory mechanisms of fruit development and ripening (Shulaev et al.,2011;Jia et al.,2013,2017;Kang et al.,2013;Han et al.,2015).While most cultivated strawberries (e.g.,F.× ananassa)are octoploid,most wild strawberries (e.g.,F.vesca)are diploid.Although CRISPR/Cas9 methods have been established in many plants,the use of this tool in strawberry needs to be further explored (Zhou et al.,2018). | Sinian Xing Meiru Jia Lingzhi Wei Wenwen Mao Usman Ali Abbasi Yaoyao Zhao Yating Chen Minglin Cao Kai Zhang Zhengrong Dai Zhechao Dou Wensuo Jia Bingbing Li | 2018 | Journal of Genetics and Genomics2018，45，12： | 4 |

| 4 | OsMPK4 promotes phosphorylation and degradation of IPA1 in response to salt stress to confer salt tolerance in rice显示文摘Salt stress adversely affects plant growth,development,and crop yield.Rice(Oryza sativa L.)is one of the most salt-sensitive cereal crops,especially at the early seedling stage.Mitogen-activated protein kinase(MAPK/MPK)cascades have been shown to play critical roles in salt response in Arabidopsis.However,the roles of the MPK cascade signaling in rice salt response and substrates of Os MPK remain largely unknown.Here,we report that the salt-induced Os MPK4-Ideal Plant Architecture 1(IPA1)signaling pathway regulates the salt tolerance in rice.Under salt stress,Os MPK4 could interact with IPA1 and phosphorylate IPA1 at Thr180,leading to degradation of IPA1.Genetic evidence shows that IPA1 is a negative regulator of salt tolerance in rice,whereas Os MPK4 promotes salt response in an IPA1-dependent manner.Taken together,our results uncover an Os MPK4-IPA1 signal cascade that modulates the salt stress response in rice and sheds new light on the breeding of salt-tolerant rice varieties. | Meiru Jia Nan Luo Xiangbing Meng Xiaoguang Song Yanhui Jing Liquan Kou Guifu Liu Xiahe Huang Yingchun Wang Jiayang Li Bing Wang Hong Yu | 2022 | Journal of Genetics and Genomics2022，49，8： | 2 |
