Rice is one of the most important food crops in the world. Weeds seriously affect the rice yield and grain quality. In recent years, there are tremendous progresses in the research and application of herbicide-resistant genes in rice worldwide. This article reviews the working mechanisms of six herbicides (glypho-sate, glufosinate, acetolactate synthase inhibitor herbicides, acetyl-CoA carboxylase inhibitor herbicides, hydroxyhenylpyruvate dioxygenase (HPPD) inhibitor herbicides and dinitroaniline herbicides), the resis-tance mutations of the corresponding herbicide-target genes, and the herbicide detoxification mecha-nisms by non-target genes. Examples are provided on herbicide-resistant rice materials obtained by transformation of exogenous resistance genes, by artificial mutagenesis and mutant screening, and by modifying the target genes through gene editing. This paper also introduces the current application of herbicide-resistant rice, points out problems that may be caused by utilization of herbicide resistant rice and solutions to the problems, and discusses the future prospects for the development of herbicide-resistant rice.

探讨耕地多功能权衡与协同关系的尺度效应对有效的耕地保护和可持续利用具有重要意义.以武汉城市圈为例,在建立评价指标体系开展耕地多功能评价的基础上,运用斯皮尔曼(Spearman)相关分析法,从4级尺度分析揭示耕地多功能权衡与协同关系的尺度变化规律.结果显示:耕地单项功能指数和多功能指数在不同尺度上呈现较明显的空间分异.耕地各功能之间的权衡与协同关系具有尺度效应,随着尺度的变化而变化.该研究可为不同层级管理决策者实施差异化耕地保护联动策略,进而促进耕地的多功能协同效应与可持续利用提供依据.
肌纤维是肌肉组织的基本结构单位,通过改变肌纤维类型组成提高肌肉品质是当前的研究热点之一.成年哺乳动物骨骼肌肌纤维类型按肌球蛋白重链基因(MyHC)的多态性表达可分为Ⅰ、2a、2x、2b型4种类型,Ⅰ、2a型属偏氧化型肌纤维,2x、2b型属偏酵解型肌纤维.动物出生前,肌纤维MyHC异构体一般表达为胚胎型、胎儿型、Ⅰ和2a型;动物出生后,肌纤维数量不再增加,肌纤维的发育主要是体积增大和类型转化,肌肉中氧化型肌纤维比例总体呈下降趋势,酵解型肌纤维比例总体呈上升趋势,且遵循Ⅰ?2a?2x?2b的变化规律.肌纤维类
从农业机械服务外包现象入手,基于相关理论分析,使用中国劳动力动态调查(CLDS)2016年数据,采用普通最小二乘(OLS)、两阶段最小二乘法(2SLS)、广义矩估计(GMM)等计量方法,分析农业女性化对农业机械服务外包的影响及其影响机制.结果表明:(1)农业女性化程度加深会明显促进农户选择农业机械服务外包.(2)当户主为小学学历、青年或中年,村庄处在西部或中部地区时,农业女性化对农户选择农业机械服务外包的影响更显著,且中年群体的激励效应大于青年,中部的激励效应大于西部.(3)农业女性化通过扩大农业劳动力约

Manipulation of flowering time to develop cultivars with desired maturity dates is fundamental in plant breeding. It is desirable to generate polyploid rapeseed (Brassica napus L.) germplasm with varying flow-ering time controlled by a few genes. In the p
The current assembled maize genomes cannot represent the broad genetic diversity of maize germ-plasms. Acquiring more genome sequences is critical for constructing a pan-genome and elucidating the linkage between genotype and phenotype in maize. Here we d
Crop yield loss due to soil salinization is an increasing threat to agriculture worldwide. Salt stress dras-tically affects the growth, development, and grain productivity of rice (Oryza sativa L.), and the improve-ment of rice tolerance to salt stress is
Heterosis, the phenomenon in which hybrids outperform their parents, has been utilized in maize (Zea mays L.) for over 100 years. To provide a more complete understanding of heterosis, we collected a com-prehensive transcriptome and translatome dataset on
Cotton architecture is partly determined by shoot branching and flowering patterns. GhBRC1 was previ-ously identified by RNA-seq analysis of nulliplex-branching and normal-branching cotton. However, the roles of GhBRC1 in cotton remain unclear. In the pre
With the increasing promotion of simplified rapeseed cultivation in recent years, the development of cul-tivars with high resistance to herbicides is urgently needed. We previously developed M342, which shows sulfonylurea herbicide resistance, by targetin
