Description
Peiqian Li, Yuanlin Sun, Baozhen Feng, and Lili Wei published a 2026 plant protection study on a bacterial protein that primes apples to resist gray mold. Gray mold, caused by Botrytis cinerea, rots fruit in storage worldwide. A friendly Bacillus strain from their lab strongly inhibits the fungus, and its secreted proteins were the suspects.
Genome analysis predicted 93 candidate secreted proteins. Screening in tobacco leaves flagged one gene whose protein triggered a strong defense response. The purified protein was then tested on apples. Fruit treated a day before fungal challenge showed far lower disease rates and milder severity than untreated fruit. Defense enzyme activity rose and damage markers fell. Treated fruit also kept better quality after harvest.
