Abstract

Bacterial isolates from maize plants showing a leaf spot disease were identified through molecular and phenotypic traits, showing that the isolates belong to Pantoea ananatis. Maize plants inoculated with those isolates showed a pathogenic reaction. This is the first report of a disease of Mexican maize caused by P. ananatis.

Additional keywords: Enterobacteriaceae, Zea mays, phytopathogen.
