苜蓿 抗寒性 秋眠性
2024/5/30
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...
Optimized nitrogen management enhances lodging resistance of rice and its morpho-anatomical, mechanical, and molecular mechanisms
氮素管理 水稻 抗倒伏性 OPT

Increasing evidence shows that improved nitrogen management can enhance lodging resistance and lower internodes play a key role in the lodging resistance of rice. However, little is known about ...
NAC transcription factor ONAC066 positively regulates disease resistance by suppressing the ABA signaling pathway in rice
NACs ABA ONAC066 SA JA
2023/4/21
NAC transcription factors have been validated as important regulators in stress responses, but their molecular mechanisms in plant disease resistance are still largely unknown. Here we report that the...
