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...
Genome-wide association mapping and gene expression analysis identify OsCPS1 as a new candidate gene controlling early seedling length in rice
