摘要

Sclerotium rolfsii Sacc. is a soil-borne pathogen causing diseases on many crops species. The pathogen produces a large number of sclerotia that can persist in soil for several years, making the disease control difficult. The use of fungicides is limited not only by their high cost, but also by the increasing concern for the environment. Flooding infested fields was reported to lead to decrease in germinability of sclerotia of the fungus (Nakagawa et al., 1994), due probably to colonisation by bacteria-like organisms. rDNA sequences of bacteria isolated from S. rolfsii sclerotia showed that about 90% of the isolates were Pantoea agglomerans (Okabe et al, 2003). No culture-independent studies for the assessment of bacteria associated with debilitation of sclerotia of S. rolfsii have been published to date. The current research aimed to study diversity of bacterial populations found with sclerotia under flooding, using rDNA-PCR DGGE and sequence data.
