Abstract:Ten soil samples were collected from various sites in Mianning, Liangshan, Sichuan province to investigate the Morchella habitat and know about the bacteria community structure and diversity in Morchella colonies by using the approach of denaturing gradient gel electrophoresis (DGGE). According to the microbial community in these samples, the bacteria community structures varied from soil samples. The diversity index (H) and abundance (S) in morels soil were higher than those of in non-morels soil. There were three sorts of prevailing microbes, they were thermosporotrichaceae, myxococcaceae, and rhodospirillaceae. The diversity of bacteria in the morel colonies was higher than that of in non–morels soils.
