已证明铜绿假单胞菌中发生基因重组。研究了 4 个菌株的 18 个生化突变体之间的杂交，尽管发现非选择性标记存在非随机分离，但尚无法得出有关基因顺序或连锁的结论。从杂交获得的后代往往比另一亲本更类似于亲本。 P的4个菌株。铜绿假单胞菌在某些组合中是不能生育的，但可以自育。没有证据表明感染因素影响生育能力，但重组后代中可能会发生生育能力的变化。
Genetic recombination has been shown to occur inPseudomonas aeruginosa. Crosses between 18 biochemical mutants of 4 strains were studied and, although non-random segregation was found for non-selective markers, it has not yet been possible to draw conclusions concerning gene order or linkage. The progeny obtained from crosses tended to resemble one parent more than the other. The 4 strains ofP. aeruginosaused were interfertile in certain combinations but self-sterile. There was no evidence for an infectious principle affecting fertility but fertility changes may occur amongst recombinant progeny.
