These bacteria perform a trick that could keep plants healthy

Researchers at Princeton University found that some soil bacteria can affect a plant's balance between growth and defense. The study in Cell Reports revealed that certain bacteria produce an enzyme called subtilase, which can reduce plant immune activity and promote root growth. Of 165 bacterial species tested, 41% suppressed stunted growth in Arabidopsis seedlings. These findings may improve understanding of microbiome-host immune system interactions in plants and animals. Further research is needed to explore potential agricultural applications without compromising disease resistance.
