Researchers discovered that Streptomyces scabiei, a bacterium known for causing common scab disease on potatoes and other root vegetables, produces various airborne chemicals with surprising benefits. Using advanced laboratory techniques, scientists identified 36 different volatile compounds from this bacterium, many of which can kill harmful fungi and potentially help plants grow better. While traditionally viewed as purely harmful, these findings suggest the bacterium may actually serve a more complex role in soil, sometimes protecting crops from more dangerous diseases.
