西南地区水稻细菌性条斑病菌的遗传多样性分析
Genotypic Diversity Analysis of Xanthomonas oryzae pv.oryzicola in Southwest China by Rep-PCR
摘要
Abstract
The genetic diversity of 141 strains ofXanthomonas oryzae pv. oryzicola from Yunnan, Guizhou and Sichuan provinces was analyzed polymorphously by Rep - PCR. Primer J3, ERIC and JELIR had better amplified polymorphism, different toxicity strains of the Rep - PCR fingerprints varied widely. Cluster analysis showed that significant genetic diversity exists within the population of Xanthomonas oryzae pv. oryzicola in Southwest China. There was a high degree of correlation between the genetic strains populations of and their pathogenicity. Strains of strong, middle or weak toxicity were roughly classified into different genetic populations. The result suggests that Rep -PCR technique can be used for detecting genetic variation among strains of Xanthomonas oryzae pv. oryzicola and identification of strains.关键词
