The IncP-1 plasmid R68 and variants R68.45 and R68.185 were tested for their chromosome donor ability in a selected recipient of Pseudomonas glycinea PGR12. It was found that variants did not express their selected characteristic of increased donor ability over that of R68 or R68.5, our commonly used donor plasmids. Coinheritance analysis of a variety of crosses provides evidence of a linkage group comprising 11 loci.
对IncP-1质粒R68及其变体R68.45和R68.185在选定的甘氨酸假单胞菌PGR12受体中进行染色体供体能力测试。结果发现，这些变体并未表现出比我们常用的供体质粒R68或R68.5更高的供体能力这一选定特征。对各种杂交组合的共遗传分析提供了一个由11个基因座组成的连锁群的证据。
