Resumen:
Background and aims Azospirillum brasilense REC3 is a plant growth-promoting and siderophore-producing bacterium isolated from strawberry. Colletotrichum acutatum M11 is the causal agent of anthracnose, an important disease in strawberry crop. The aim of this study was to characterize at the biochemical and molecular level, the systemic resistance induced by A. brasilense on pathogen-challenged strawberry plants. Methods Phytopathological tests were performed; the content of phenolic compounds was determined spectrophotometrically; callose depositions in leaves by aniline blue staining; salicylic acid (SA) content in leaves by HPLC; and defense-related gene expression [pathogenesis-related proteins (FaPR1), chitinases (FaChi2-1; FaChi2-2) and glucanase (FaBG2-2)] by RT-PCR.
