Abstract

Rhizobium sp. strain NGR234 contains three replicons: the symbiotic plasmid or pNGR234a, a megaplasmid (pNGR234b), and the chromosome. Symbiotic gene sequences not present in pNGR234a were analyzed by hybridization. DNA sequences homologous to the genes fixLJKNOPQGHIS were found on the chromosome, while sequences homologous to nodPQ and exoBDFLK were found on pNGR234b.

摘要

根瘤菌属的NGR234菌株含有三个复制子:共生质粒或pNGR234a、一个大质粒(pNGR234b)和染色体。通过杂交分析了pNGR234a中不存在的共生基因序列。在染色体上发现了与fixLJKNOPQGHIS基因同源的DNA序列,而在pNGR234b上发现了与nodPQ和exoBDFLK同源的序列。
