Hydrolase P1 in Bacillus velezensisHN‐2 confers tobacco resistance by delaying TMV infection

Hydrolase protein P1 acts as an elicitor to induce systemic resistance in the tobacco plant against TMV Infection. These findings provide an experimental foundation for the application of B. velezensis HN-2 in biological control strategies and offer theoretical insights into the use of Bacillus-derived proteins for TMV management. © 2025 Society of Chemical Industry.
