Differentiation of Leaf-Streak and Blight Pathogens of Rice by Immunoelectrophoresis. O. R. Reddy, Assistant Plant Pathologist, Plant Quarantine & Fumigation Station, Madras-600001, India. Plant Dis. 65:607-608. Copyright 1981 American Phytopathological Society. DOI: 10.1094/PD-65-607.

Isolates of the leaf-streak pathogen (Xanthomonas translucens f. sp. oryzicola) produced two overlapping precipitin bands with different electrophoretic mobilities, but the blight bacterium (X. oryzae) formed only one precipitin band against homologous antisera. Also, the leaf-streak antigen did not cross-react with the blight pathogen antiserum and vice versa.
