The community diversities of endophytic bacteria in seeds of two types of super hybrid rice ("Shenliangyou 5814" and "Y Liangyou 900") were studied through culture-independent method of the 16S rDNA clone library technique.Experimental result showed that the endophytic bacterial communities in "5814" included 13 OTUs,and the abundance of the first dominant bacterium Pantoea was 89.44%,the second and third dominant bacterium was Flavobacteriu and Methylobacterium.The endophytic bacterial communities in "900" included 13 OTUs,and the abundance of the first dominant bacterium Pantoea was 76.11%,the second and third dominant bacterium was Pseudomonas and Xanthomonas.From this study,we found that Pantoea was the dominant genera in hybrid rice seeds,and the endophytic bacterial community structure had certain relevance to the seeds of hybrid rice which had been genetically related.
