Abstract

As a natural attribute of clean and healthy soil, fungistasis is an important indicator of soil quality, and has positive ecological significance to the inhibition of plant disease eruption caused by soil-borne fungal pathogens. In this study, soil samples (0-15 cm) were collected from the abandoned land at Shenyang Experimental Station of Ecology, Chinese Academy of Sciences, to which pesticides and fertilizers have never been applied for nearly 10 years. A series of soil samples with gradient fungistasis was obtained by heating (CK, 100°C, 110°C, and 121°C for 4 min, respectively), and bacterial community structure was analyzed by Polymerase Chain Reaction coupled with Denaturing Gradient Gel Electropboresis method (PCR-GGGE). The results showed that there was a significant correlation between soil fungistasis and bacterial community composition. Treatment CK showed the strongest capacity to control the growth of target soil-borne pathogenic fungi. The further the bacterial community structure of treated soil deviated from that of CK, the lower the soil fungistasis was. Sequencing and the following phylogenetic analysis of special bands in DGGE indicated that Sphingomonas asaccharolytica, Nitrospira sp., Hyphomicrobiaceae sp., Bacillus megaterium, and Micrococcus sp. could be involved in soil fungistasis.
