Gypsy retrotransposon-derived maize lncRNA GARR2 modulates gibberellin response
Gypsy retrotransposon-derived maize lncRNA GARR2 gibberellin
2023/7/20
Long non-coding RNAs (lncRNAs) mediate diverse biological events mainly through the modulation of transcriptional hierarchy. The phytohormone gibberellin (GA) is essential for various aspects of plant...

多倍体 遗传变异 植物育种
2022/3/23
杂交和回交是常用的动、植物育种手段。杂交引起的父母基因互作导致遗传和表观遗传变异，比如经典的副突变(paramutation）可以跨代遗传。但是，由表观遗传引起的跨代遗传的机理缺乏全基因组水平上的研究。2月9日，南京农业大学多倍体杂种优势研究团队在Genome Biology（IF=13.583）上发表了题为Small RNAs mediate transgenerational inherita...
水分关键期干旱是影响玉米生长和产量的主要限制因子，构建此时期玉米干旱损失模型，研究干旱指数天气保险，对于合理设计天气指数保险和解决目前传统农业保险的困境，转移农业气象灾害风险具有重要意义。针对作物特定阶段单因子气象灾害影响难以剥离的问题，本研究在西北农林科技大学旱作农业长武试验站进行了连续3a的雨养玉米观测试验，利用田间试验数据（玉米生长发育数据、气象数据、土壤数据和田间管理数据）对CERES-M...

基于CERES-Maize模型的吉林春玉米遗传参数调试
春玉米 CERES-Maize 遗传参数 吉林
2017/11/16
为了应用CERES-Maize模型模拟吉林春玉米生长发育和产量形成，需要确定主栽春玉米品种的遗传参数。采用晚熟春玉米品种‘吉单159’和‘先玉335’多年田间观测数据和同期气象、土壤等数据进行遗传参数调试，并对模型的模拟效果进行验证。结果表明：2个春玉米品种生育期的模拟值和实测值散点均在1:1线周围。‘吉单159’播种至开花天数和播种至成熟天数RMSE值分别为3.78和10.90。‘先玉335’播...
