Abstract

Corn (Zea mays) is from the cereal category and the large wheat family; it is the third crop after wheat and rice cultivated areas worldwide. This research aims to investigate the detection and identification of the pathogenic bacterium Pantoea dispersa in Iran using biochemical and molecular identification methods and the host range of this bacterial species. For this purpose, in two consecutive years, sampling was done from the corn fields of different provinces of Iran, which have symptoms such as leaf spots and wilting. Standard plant bacteriology methods were used to isolate bacteria with the mentioned symptoms, and isolates were identified using biochemical characteristics and primers related to housekeeping genes. In the investigation of pathogenicity and host range of 20 bacterial isolates obtained from different corn fields, six isolates were identified as P. dispersa. This is the first report of the presence of the bacterium in Iran. In examining the host range of the mentioned isolates millet and sourghum are introduced as new hosts of this species in Iran.
