Phyllospheric application of Bacillus mucilaginosus mediates the recovery of tea plants exposed to low-temperature stress by alteration of leaf endophytic community and plant physiology

This study showed that B. mucilaginosus could significantly change the community structure of leaf endophytic populations, and increase antioxidant enzyme activity and osmolyte content in tea plants after low-temperature stress, promoting the rapid recovery of photosynthesis, and thereby benefiting the recovery of tea plant leaves. This study provided a theoretical basis for the application of B. mucilaginosus in practical production and also provided new ideas for the recovery of tea plants exposed to low-temperature stress.
