Tóm tắt

Autotoxicity is a significant contributor to replant disease, with phenolic acid autotoxins such as 4-HBA (ρ-hydroxybenzoic acid) influencing the structure of the rhizosphere microbial community by modifying the secretion characteristics of grapevine roots. In the study, 'Beta' grape seedlings were selected to investigate the regulatory mechanism of 4HBA on root metabolism and secreting characteristics. The results showed that the expression level of genes related to primary and secondary metabolism in the roots was affected by 100 μg mL
