Integrative Taxonomy of Novel Diaporthe Species Associated with Medicinal Plants in Thailand

“…Diaporthe species are a large and diverse group of fungi known as endophytes, saprobes, and plant pathogens, with worldwide distribution and a broad range of host associations [ 13 , 14 , 15 , 16 , 17 , 18 ]. Pathogenic Diaporthe species cause various plant diseases, such as blight, cankers, diebacks, fruit rots, leaf spots, and wilts, on forest trees [ 19 , 20 , 21 , 22 ] and many agricultural crops such as citrus, grapevine, peach, soybean, sunflower, and tea [ 23 , 24 , 25 , 26 , 27 , 28 ]. Morphologically, Diaporthe is characterized by pseudostromatic ascomata that usually have black lines in the host substrate, along with elongated perithecial necks for the sexual morph [ 29 ], and asexual morph consisting of ostiolate conidiomata, aseptate, and polymorphic (alpha, gamma, and beta), and hyaline conidia [ 14 ].…”

“…Norphanphoun et al [ 32 ] classified Diaporthe into 13 species complexes based on a comprehensive sequence dataset of five loci (ITS, tef1-α , tub2 , cal , and his3 ) to assist species delineation. The integrative approach based on cultural, ecological, morphological, and molecular characteristics is advantageous for accurately identifying Diaporthe species [ 22 , 27 , 28 , 35 , 36 , 37 ].…”

“…Taxonomic studies of Diaporthe revealed a variety of medicinal plants as their hosts [ 38 ]. However, most of these studies have been conducted in temperate zones (i.e., [ 15 , 16 , 17 , 21 , 24 , 26 , 28 ]). Knowledge of Diaporthe associated with medicinal plants in the tropics is still limited [ 31 , 32 ].…”
