Plant growth-promoting rhizobacterium Bacillus cereus AR156 induced systemic resistance against multiple pathogens by priming of camalexin synthesis.

Phytoalexins play a crucial role in plant immunity. However, the mechanism of how phytoalexin is primed by beneficial microorganisms against broad-spectrum pathogens remains elusive. This study showed that Bacillus cereus AR156 could trigger ISR against broad-spectrum disease.

Analysis of the composition and characteristics of culturable endophytic bacteria within subnival plants of the Tianshan Mountains, northwestern China.

This study first described the composition and characteristics of culturable endophytic bacteria isolated from wild alpine-subnival plant species growing under extreme environmental conditions (i.e., on the border of a glacier with frequently fluctuating and freezing temperatures, strong wind, and high ultraviolet radiation).
