Pinus armandii Endophytic Biocontrol SynCom

Community ID CommunityMech:000280
Ecological State ENGINEERED
Environment Pinus armandii endosphere (endophytic host tissues)
ENVO:01001001

A five-strain synthetic bacterial community (SynCom) assembled from endophytic bacteria isolated from multiple tissues of Pinus armandii to promote seedling growth and prime blister rust-associated defense responses. The optimized, functionally complementary SynCom comprises Pseudomonas koreensis RC1, Paenibacillus terrae RE7, Bacillus velezensis OB3 and NA3, and Bacillus subtilis NA11, selected for plant growth-promoting traits (nitrogen fixation, phosphate and potassium solubilization, IAA production) and antagonism of the rust pathogen. In pot experiments the SynCom increased seedling height and biomass and raised defense-related polyphenol oxidase and peroxidase activities relative to the control.
