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
rice shoot length genome-wide association study OsCPS1 selection
2023/4/21
High seedling vigor can improve the ability to compete against weeds and flooding at the seedling stage and is essential for the direct seeding of rice. Early shoot length is an important performance ...
Physiological and genome-wide gene expression analyses of cold-induced leaf rolling at the seedling stage in rice (Oryza sativa L.)☆
Rice (Oryza sativa L.) Cold-induced leaf yellowing Cold-induced leaf rolling Physiological analysis
2023/4/21
Leaf rolling and discoloration are two chilling-injury symptoms that are widely used as indicators for the evaluation of cold tolerance at the seedling stage in rice. However, the difference in cold-r...
