Alfalfa (Medicago sativa L) is a high-quality forage for ruminants and the main stem is the dominant morphological component contributing to the forage nutritive value in mature alfalfa forage. Sheari...
共生固氮根瘤的形成是根瘤菌和宿主植物相互作用的结果. 根瘤菌和宿主植物产生的众多信号分子控制着宿主植物为根瘤发育和维持根瘤功能所必需的基因, 使这些基因在根瘤发育过程中有序地表达. 为识别这些基因, 本研究比较了紫花苜蓿根瘤和根的cDNA扩增片段长度多态性(cDNA-amplified fragment length polymorphism, cDNA-AFLP). 在约3000余个cDNA片段...
