Abstract

A pLAFR1 cosmid clone (pPP346) carrying the nodulation region of the symbiotic plasmid pRme41b was isolated from a gene library of Rhizobium meliloti 41 by direct complementation of a Nod- deletion mutant of R. meliloti. Agrobacterium tumefaciens and Rhizobium species containing pPP346 were able to form ineffective nodules on alfalfa. The 24-kilobase insert in pPP346 carries both the common nodulation genes and genes involved in host specificity of nodulation. It was shown that these two regions are essential and sufficient to determine the early events in nodulation. A new DNA region influencing the kinetics and efficiency of nodulation was also localized on the symbiotic megaplasmid at the right side of the nif genes.

摘要

通过苜蓿根瘤菌Nod-缺失突变体的直接互补，从苜蓿根瘤菌41的基因文库中分离出一个携带共生质粒pRme41b结瘤区域的pLAFR1黏粒克隆（pPP346）。含有pPP346的根癌农杆菌和根瘤菌能够在苜蓿上形成无效根瘤。pPP346中24千碱基的插入片段既携带共同结瘤基因，也携带参与结瘤宿主特异性的基因。结果表明，这两个区域对于确定结瘤早期事件是必不可少且足够的。一个影响结瘤动力学和效率的新DNA区域也定位在固氮基因右侧的共生大质粒上。
