Abstract
A bacterial disease of walnut (Juglans regia) has been observed in northwestern Iran during the summer of 2018 with symptoms similar to the shallow bark canker on trunks and branches. In the present study, two hundred and thirty-six obtained isolates were characterized and classified into three major groups based on the biochemical and physiological characters. With the species-specific primer pairs, Brenneria rubrifaciens was not detected, and a few isolates were recognized as B. nigrifluens. The partial 16S rDNA sequences and multilocus sequence analysis based on housekeeping genes gyrB, rpoB, infB, and atpD following a phylogenetic analysis revealed that the isolates are belonged to B. roseae subsp. roseae, B. nigrifluens and Gibbsiella quercinecans (190 out of 236 isolates) species. Iranian isolates formed the monophyletic clades and had high sequence similarity with the relative type strains. The pathogenicity tests of G. quercinecans, B. roseae subsp. roseae and B. nigrifluens isolates on branches and trunks of 5-year-old walnut trees indicated that they had effective potential to cause necrosis and canker on branches. The effective identification of potentially pathogenic bacterial species associated to the canker disease of walnut trees was confirmed using species-specific primer pairs and concatenated partial sequences of housekeeping genes. Further investigation is necessary to determine the agents might be involved in the etiology of the disease.
