| 1 | Genomic decoding of breeding history to guide breeding-by-design in rice显示文摘Deciphering the intrinsic molecular logic of empirical crop breeding from a genomic perspective is a decisive prerequisite for breeding-by-design(BbD),but remains not well established.Here,we decoded the historical features of past rice breeding by phenotyping and haplotyping 546 accessions covering the majority of cultivars bred in the history of Northeast China(NEC).We revealed that three groups founded the genetic diversities in NEC rice with distinct evolution patterns and traced and verified the breeding footprints to known or genome-wide association study(GWAS)-detected quantitative trait loci(QTLs),or introgressions from indica sub-species with chronological changes in allele frequencies.Then we summarized a rice breeding trend/principle in NEC,and combined with the successful example in breeding and application of Zhongkefa5 to demonstrate the guiding value of our conclusion for BbD in practice.Our study provides a paradigm for decoding the breeding history of a specific crop to guide BbD,which may have implications in different crop breeding. | Zhuo Chen Qingyun Bu Guifu Liu Maoqing Wang Hongru Wang Huazhao Liu Xiufeng Li Hong Li Jun Fang Yan Liang Zhenfeng Teng Sai Kang Hong Yu Zhukuan Cheng Yongbiao Xue Chengzhi Liang Jiuyou Tang Jiayang Li Chengcai Chu | 2023 | National Science Review2023，10，5： | 1 |
| 2 | An activated form of NB-ARC protein RLS1 functions with cysteine-rich receptor-like protein RMC to trigger cell death in rice显示文摘A key event that follows pathogen recognition by a resistance(R)protein containing an NB-ARC(nucleotide-binding adaptor shared by Apaf-1,R proteins,and Ced-4)domain is hypersensitive response(HR)-type cell death accompanied by accumulation of reactive oxygen species and nitric oxide.However,the integral mechanisms that underlie this process remain relatively opaque.Here,we show that a gain-offunction mutation in the NB-ARC protein RLS1(Rapid Leaf Senescence 1)triggers high-light-dependent HR-like cell death in rice.The RLS1-mediated defense response is largely independent of salicylic acid accumulation,NPR1(Nonexpressor of Pathogenesis-Related Gene 1)activity,and RAR1(Required for Mla12 Resistance 1)function.A screen for suppressors of RLS1 activation identified RMC(Root Meander Curling)as essential for the RLS1-activated defense response.RMC encodes a cysteine-rich receptor-like secreted protein(CRRSP)and functions as an RLS1-binding partner.Intriguingly,their co-expression resulted in a change in the pattern of subcellular localization and was sufficient to trigger cell death accompanied by a decrease in the activity of the antioxidant enzyme APX1.Collectively,our findings reveal an NBARC-CRRSP signaling module that modulates oxidative state,the cell death process,and associated immunity responses in rice. | Yiqin Wang Zhenfeng Teng Hua Li Wei Wang Fan Xu Kai Sun Jinfang Chu Yangwen Qian Gary JLoake Chengcai Chu Jiuyou Tang | 2023 | Plant Communications2023，4，2： | 1 |
| 3 | Synthesis of pyrimidines from dinitrogen and carbon显示文摘The element nitrogen and nitrogenous compounds are vital to life.The synthesis of nitrogen-containing compounds using dinitrogen as the nitrogen source,not through ammonia,is of great interest and great value but remains a grand challenge.Herein,we describe a strategy to realize this transformation by combining the heterogeneous approach with the homogeneous methodology.The N_(2)molecule was first fixed with carbon and LiH through a one-pot heterogeneous process,forming Li_(2)CN_(2)as an’activated’nitrogen source with high efficiency.Then subsequent homogeneous treatments of Li_(2)CN_(2)to construct the organic synthon carbodiimide and the RNA/DNA building block pyrimidines were fulfilled.By using^(15)N_(2)as the feedstock,their corresponding^(15)N-labeled carbodiimide and pyrimidines were readily obtained.This homogeneous-heterogeneous synergy strategy will open a new chapter for N_(2)transformation. | Xianghui Shi Qianru Wang Chao Qin Li-Jun Wu Yuanjin Chen Gao-Xiang Wang Yongli Cai Wenbo Gao Teng He Junnian Wei Jianping Guo Ping Chen Zhenfeng Xi | 2022 | National Science Review2022，9，12： | 0 |
