Cross‐reactive antigens were detected in crude and semi‐purified preparations from acetone powder of Citrus aurantifolia and Citrus sinensis leaves with antisera to Xanthomonas campestris pv. citri pathotypes A and C by DAS‐ELISA. Antiserum to X. campestris pv. citri pathotype C revealed an antigenic disparity between C. aurantifolia (susceptible host to pathotype C) and C. sinensis (resistant host to pathotype C) whereas antiserum to X, campestris pv. citri pathotype A did not reveal any antigenic disparity between these hosts, both susceptible to pathotype A. The occurrence of “key” cross‐reactive antigens in Citrus species and X. campestris pv. citri and their possible involvement in such interaction are discussed.
