Antifungal activity of OsCLP protein. A, growth inhibition of R. solani by OsCLP protein. One, two, or five micrograms of purified OsCLP protein were pipetted onto filter paper disks on PDA medium after inoculation with R. solani. BSA (5 μg) was used as a negative control. B, C, microscopic view of growing R. solani hyphae treated with 5 μg BSA or 5 μg OsCLP. Arrows indicate regions of cell wall degradation.
