Article Synopsis
- Accumulation of p-hydroxybenzoic acid (PHBA) in soil leads to autotoxicity stress in cucumbers, but this stress can be reduced by introducing PHBA-degrading bacteria like Klebsiella strain P620.
- In experiments, soil with P620 showed improved cucumber growth, lower PHBA levels, and enhanced activities of various soil and antioxidant enzymes compared to PHBA stress alone.
- Metabolomic and transcriptomic analyses reveal that P620 alters microbial communities in contaminated soil, influencing metabolites in the plant leaves and down-regulating specific genes, contributing to the mitigation of PHBA stress.

Continuous-cropping leads to obstacles in crop productivity by the accumulation of -hydroxybenzoic acid (PHBA) and ferulic acid (FA). In this study, a strain CFA of was shown to have a higher PHBA- and FA-degrading ability in media and soil and the mechanisms underlying this were explored. Optimal conditions for PHBA and FA degradation by CFA were 0.

- Ferulic acid (FA) and -hydroxybenzoic acid (PHBA) accumulate in the rhizosphere of cucumber plants, causing stress, but how they degrade in soil is not well studied.
- A strain named CSY-P13 was isolated and shown to effectively degrade both compounds in lab conditions and in soil, resulting in beneficial byproducts and improved cucumber health.
- By inoculating CSY-P13 into soil, there was observed activation of antioxidant enzymes, changes to the soil bacterial community, and enhanced enzyme activity, all contributing to reduced plant stress from FA and PHBA.
