This article discusses a study on the role of autotoxin-degrading bacteria in alleviating replant problems in tobacco crops. The researchers found that Pseudomonas and Burkholderia species were more abundant in soil with autotoxin-degrading bacteria, and they isolated two strains of bacteria that efficiently degrade vanillin, a component of autotoxin. Inoculating these bacteria into vanillin-modified soil improved the growth of tobacco seedlings. The study suggests that autotoxin-degrading bacteria have the potential to promote soil health and crop growth. [Extracted from the article]
