Short Communication


Diaporthe spp. isolated from stem-end rot lesions of several cultivars of mango were phylogenetically identified as Diaporthe arecae, Diaporthe eugeniae, Diaporthe pascoei, Diaporthe perseae, and Diaporthe ueckerae based on Internal Transcribed Spacer, Translation Elongation Factor-1α, and β-tubulin sequences. Pathogenicity test showed that species identified as D. pascoei and D. ueckerae isolates produced stem-end rot symptoms on tested mango cvs Chok Anan, Waterlily, and Falan. Diaporthe arecae was pathogenic both on Chok Anan and Waterlily, while D. perseae produced rotting symptoms only on Chok Anan. Diaporthe eugeniae was not pathogenic in all tested mango cultivars. Our study indicates that pathogenic Diaporthe spp. are possibly opportunistic pathogens.
