黄芪根瘤菌CA8561和JL84的部分16SrRNA基因序列的测定

PARTIAL 16S rRNA GENE SEQUENCING OF RHIZOBIAL STRAINS CA8561 AND JL84 ISOLATED FROM ASTRAGALUS

报导了黄芪根瘤菌ＣＡ８５６１和ＪＬ８４的部分１６ｓｒＲＮＡ基因序列，测算了它们与已知根瘤菌、茎瘤菌各属模式种之间的遗传距离．结果表明，ＣＡ８５６１和ＪＬ８４均具有独立的进化路线，充分显示了黄芪根瘤菌的遗传多样性．

Partial 16S rRNA gene sequence of rhizobinl strains CA8561 and JL84 isolated from Astrogalus spp.was determined,The genetic distance between CA8561 or JL84 and all described rhizobial type species wascalculated,and it was found that the strain CA8561 or JL84 was of unique evolutionary geneline. These results showed the rhixobia isolated from Astragalus spp. was genetic diversity.
