Comparison of Soil Microbial Composition in Rhizospheres Between Wilt Disease-Resistant and Susceptible Melon Varieties

Résumé fourni par la source

To screen out the bio-control soil microorganisms for preventing melon wilt, soil microbial compositions in rhizospheres between wilt-resistant and susceptible melon varieties were analyzed. The results showed that the soil fungal richness in rhizospheres of wilt-resistant melon varieties (MT) was significantly higher than that of wilt-susceptible melon varieties (MS). Additionally, in comparison with MS, soil bacterial compositions, such as Proteobacteria, Bacteroidota, Acidibacter, Streptomyces, etc., and the soil fungal compositions, such as Penicillium, Derxomyces, Aspergillus, and Talaromyces, enriched; also, Trichoderma, Gibellulopsis, and Pseudallescheria decreased in rhizospheres of wilt-resistant melon varieties (MT). Moreover, Mycothermus, Zopfiella, and Cladorrhinum were the unique soil-dominant fungal genera in rhizospheres of MT. All the above results suggested that the soil bacterial communities, such as Proteobacteria, Bacteroidota, Acidibacter, Streptomyces, etc., and the soil fungal communities, such as Penicillium, Derxomyces, Aspergillus, Talaromyces Mycothermus, Zopfiella, and Cladorrhinum, could be speculated as the potential soil bio-control microorganisms for preventing melon wilt.
