Control effects and mechanisms of metabolites from Streptomyces ahygroscopicus var. gongzhulingensis strain 769 on sclerotinia rot in sunflowers

mycolabadmin

Scientists discovered that a beneficial soil bacterium called Streptomyces can effectively control sunflower rot disease caused by a harmful fungus. When applied to soil or roots, this bacterium reduced disease severity by over 50% and improved plant root health and seed quality. The treatment works by both directly killing the pathogenic fungus and strengthening the plant’s natural defense systems.

Integrated multi-omics identifies plant hormone signal transduction and phenylpropanoid biosynthesis as key pathways in kiwifruit (Actinidia chinensis var. deliciosa) resistance to Botryosphaeria Dothidea infection

mycolabadmin

Kiwifruit can be infected by a fungus called Botryosphaeria dothidea, which causes soft rot and makes the fruit inedible. Researchers used advanced techniques to study what happens inside the fruit when infected, finding that certain plant hormones and chemical pathways become active to fight the infection. They identified two key genes that appear to control how the fruit responds to the fungus, which could help develop better ways to prevent this costly disease.
