TRANSTHYRETIN-LIKE and BYPASS1-LIKE co-regulate growth and cold tolerance in Arabidopsis
BYPASS1-LIKE TRANSTHYRETIN-LIKE Plant growth Cold tolerance Arabidopsis
<
2024/1/11
Background: Cold stress inhibits normal physiological metabolism in plants, thereby seriously affecting plant development. Meanwhile, plants also actively adjust their metabolism and development to ad...
Maternal transmission of the epigenetic ‘memory of winter cold’ in Arabidopsis
Arabidopsis memory of winter cold epigenetic environmental memories chromatin state

多年生苜蓿以根的形式越冬，因此，苜蓿的抗寒性以及成功越冬的关键在于其根部的抗寒性。在没有叶绿体结构不能进行光合作用的根部，呼吸作用是维持根部细胞生长所需能量ATP的唯一途径。新疆农业大学刘美君副教授团队选用不同秋眠级的新牧4号(秋眠级为2) 和甘农5号(秋眠级为8) 的紫花苜蓿为试验材料，研究发现，低温显著影响了苜蓿根系细胞呼吸代谢，细胞线粒体电子传递链复合体复合体II、III和IV受抑明显致使氧...
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。
