[EN] Although several strains of B. subtilis with antifungal activity have been isolated worldwide, to date there are no published reports
regarding the isolation of a native B. subtilis strain from strawberry plants in Mexico. A native bacterium (Bacillus subtilis 21)
demonstrated in vitro antagonistic activity against different plant pathogenic fungi. Under greenhouse conditions, it was shown
that plants infected with Rhizoctonia solani and Fusarium verticillioides and treated with B. subtilis 21 produced augment in the
number of leaves per plant and an increment in the length of healthy leaves in comparison with untreated plants. In addition, B.
subtilis 21 showed activity against pathogenic bacteria. Secreted proteins by B. subtilis 21 were studied, detecting the presence of
proteases and bacteriocin-like inhibitor substances that could be implicated in its antagonistic activity. Chitinases and zwittermicin
production could not be detected. Then, B. subtilis 21 could potentially be used to control phytopathogenic fungi that infect
strawberry plants.
