南京农业大学农学院《New Phytologist》发表张文利课题组“R‐loops act as regulatory switches modulating transcription of COLD‐responsive genes in rice”（图）
张文利 气候变化 分子机制 作物生长
2023/10/28
随着全球气候变化的不断加剧，低温冻害和冷害已经成为影响农作物生长的一个重要自然胁迫因素。冷胁迫通常影响农作物正常的生长发育进程，严重时导致减产甚至颗粒无收。因此，作物冷应答分子机制研究可为作物耐冷分子育种提供理论参考。植物R-loop在不同的细胞活动中发挥重要作用，包括发育调控和胁迫应答等。然而，在低温敏感型作物如水稻中，R-loop介导冷胁迫应答的分子机制仍鲜有报道。

High-resolution temporal dynamic transcriptome landscape reveals a GhCAL-mediated flowering regulatory pathway in cotton (Gossypium hirsutum L.)
棉花开花 相关基因 GhCAL
2024/5/17
本研究利用不同熟性的棉花高分辨率时间动态转录组，鉴定到棉花开花相关基因GhCAL，并对其介导的棉花开花调节途径进行了解析。研究发现GhCAL基因沉默的转基因棉花植株花芽分化和开花时间显著延迟，GhCAL能够与GhAP1-A04/GhAGL6-D09形成异源二聚体，同时调节GhAP1-A04和GhAGL6-D09的表达。GhAP1-A04和GhAGL6-D09沉默的棉花植株也表现出明显的开花延迟。因...
