作者 刘友勋 黄娟 《当代生态农业》 2010年第3期13-16,12,共5页
采用引物BOX和ERIC对来自4省的35个细条病菌菌株进行Rep-PCR扩增,BOX引物扩增出14条指纹带,10种谱型,以致病型为单位计算遗传多样性值为0.63~1.00;ERIC引物扩增出19条指纹带,17种谱型,遗传多样性值为0.86~1;引物ERIC比BOX在遗传多样... 采用引物BOX和ERIC对来自4省的35个细条病菌菌株进行Rep-PCR扩增,BOX引物扩增出14条指纹带,10种谱型,以致病型为单位计算遗传多样性值为0.63~1.00;ERIC引物扩增出19条指纹带,17种谱型,遗传多样性值为0.86~1;引物ERIC比BOX在遗传多样性方面有更好的分辨率;树状聚类图反映的遗传分簇差异,与菌株的致病型及其地理的来源之间没有相关性。 展开更多

Rice bacterial leaf streak,caused by Xanthomonas oryzae pv.oryzicola,is an important bacterial disease in rice-planting areas in South China and Southeast Asian countries.It occurs every year in local areas.This paper reviews the research advance in the occurrence and harms of rice bacterial leaf streak in China,classification of Xanthomonas oryzae and infection characteristics,pathogenic factors and pathogenicity of rice bacterial leaf streak and breeding of bacterial leaf streakresistance rice cultivars.Some issues involved in occurrence and control of rice bacterial leaf streak were presented,and the areas on which the future studies might be focused were discussed. 展开更多
