| 2 | Resistance of Barnyard Grass(Echinochloa crusglli) to Quinclorac in Double-harvest Rice Area in Hunan Province of China显示文摘[Objective]The paper was to study the resistance of barnyard grass to quinclorac in double-harvest rice area in Hunan Province of China.[Method]Using whole-plant determination method,the resistance of 36 biotypes of barnyard grass to quinclorac in double-harvest rice area in Hunan Province was studied.[Result]The biotype collected from Lijiaping Town of Shaoyang County was the most susceptible barnyard grass to quinclorac,and the EC50value was 70.253 1 g a.i./hm2,so it was recognized as the sensitive biotype.The biotypes collected from Caowei Town of Yuanjiang County(HN3 and HN4 from direct seeding rice fields)and Zhongyukou Town of Nanxian County presented very high resistance to quinclorac;the EC50values were 1 999.122 5,1 664.544 6 and 1 022.739 5 g a.i./hm2,and their resistance indexes reached 28.46,23.69 and 14.56,respectively,indicating that these three biotypes had high level of resistance to quinclorac.EC50values of about 22 biotypes were ranged from 144.837 3 to 408.289 4 g a.i./hm2,and resistance indexes were ranged from 2.06 to 5.81,indicating that these biotypes had produced resistance to quinclorac.EC50values of other 10 biotypes were ranged from 98.032 6 to 138.660 9 g a.i./hm2,and the resistance indexes were ranged from 1.40 to 1.97,indicating that the sensitivity of barnyard grass in these places was decreasing.[Conclusion]The paper provided guidance for scientific and rational use of quinclorac in paddy fields. | Ma Guolan Liu Ducai Liu Xueyuan Tang Tao Peng Yajun | 2013 | Plant Diseases and Pests2013，4，5： | 1 |

| 4 | Genomic insights into the origin, adaptive evolution, and herbicide resistance of Leptochloa chinensis, a devastating tetraploid weedy grass in rice fields显示文摘Chinese sprangletop (Leptochloa chinensis), belonging to the grass subfamily Chloridoideae, is one of the most notorious weeds in rice ecosystems. Here, we report a chromosome-scale reference genome assembly and a genomic variation map of the tetraploid L. chinensis. The L. chinensis genome is derived from two diploid progenitors that diverged ∼10.9 million years ago, and its two subgenomes display neither fractionation bias nor overall gene expression dominance. Comparative genomic analyses reveal substantial genome rearrangements in L. chinensis after its divergence from the common ancestor of Chloridoideae and, together with transcriptome profiling, demonstrate the important contribution of tetraploidization to the gene sources for the herbicide resistance of L. chinensis. Population genomic analyses of 89 accessions from China reveal that L. chinensis accessions collected from southern/southwestern provinces have substantially higher nucleotide diversity than those from the middle and lower reaches of the Yangtze River, suggesting that L. chinensis spread in China from the southern/southwestern provinces to the middle and lower reaches of the Yangtze River. During this spread, L. chinensis developed significantly increased herbicide resistance, accompanied by the selection of numerous genes involved in herbicide resistance. Taken together, our study generated valuable genomic resources for future fundamental research and agricultural management of L. chinensis, and provides significant new insights into the herbicide resistance as well as the origin and adaptive evolution of L. chinensis. | Lifeng Wang Xuepeng Sun Yajun Peng Ke Chen Shan Wu Yanan Guo Jingyuan Zhang Haona Yang Tao Jin Lamei Wu Xiaomao Zhou Bin Liang Zhenghong Zhao Ducai Liu Zhangjun Fei Lianyang Bai | 2022 | Molecular Plant2022，15，6： | 1 |
