ABSTRACT
Continuous cropping often results in severe "replant problem," across various crops due to the autotoxins accumulation, soil acidification, pathogens proliferation, and microbial dysfunction. We unveiled a groundbreaking phenomenon that long-term continuous cropping (LTCC) can alleviate the tobacco replant problem. This mitigation occurs through the enrichment of autotoxin-degrading microbes, and the transformative impact is evident with even a modest application (10%) of LTCC soil to short-term continuous cropping (STCC) soil. Our investigation has pinpointed specific autotoxin-degrading bacteria, particularly the Pseudomonas and Burkholderia species, which exhibit the capacity to alleviate the tobacco replant problem in STCC soil. Their autotoxin-degrading mechanism using axenic culture and soil samples was also conducted via comprehensive analyses of microbiome and transcriptome approach. This research sheds light on the potential of LTCC as a strategic approach for sustainable agriculture, addressing replant problems and promoting the health of cropping systems.
