摘要

尽管是一个小岛,斯里兰卡却有着丰富的真菌多样性。迄今为止,来自斯里兰卡的大多数真菌已被确定为蔬菜、水果和种植园作物的病原体。多孢子菌属曲霉属(多孢子菌)包括植物致病性、腐殖性、内生性和人/动物机会致病性真菌。大多数与植物相关的曲霉属物种都是从水煮宿主中发现的。在目前的研究中,对该国的22个地理位置进行了探索,并从10种不同的水煮宿主中收集了水煮。基于核内转录间隔序列1和2 (ITS)、甘油醛-3-磷酸脱氢酶(gapdh)和翻译伸长因子1-α (tef1) 3个位点的形态和分子系统发育支持了本文所描述的两个新种真菌的描述,即C. aurantia sp. 11和C. vidyodayana sp. 11。此外,C. changmaiensis、C. falsilunata、C. lonarensis、C. plantarum、本文对假短孢子菌进行了更新。此外,曲霉属中的5种(C. asiatica、C. geniculata、C. lunata、C. muehlenbeckiae和C. verruculosa)代表了斯里兰卡真菌的新记录。

Molecular phylogeny and morphology reveal two new graminicolous species, Curvularia aurantia sp. nov. and C. vidyodayana sp. nov. with new records of Curvularia spp. from Sri Lanka
Despite being a small island, Sri Lanka is rich in fungal diversity. Most of the fungi from Sri Lanka have been identified as pathogens of vegetables, fruits, and plantation crops to date. The pleosporalean genus Curvularia ( Dothideomycetes ) includes phytopathogenic, saprobic, endophytic, and human/animal opportunistic pathogenic fungal species. The majority of the plant-associated Curvularia species are known from poaceous hosts. During the current study, 22 geographical locations of the country were explored and collections were made from 10 different poaceous hosts. Morphology and molecular phylogeny based on three loci, including nuclear internal transcribed spacers 1 and 2 with 5.8S nrDNA (ITS), glyceraldehyde-3-phosphate dehydrogenase ( gapdh ), and translation elongation factor 1-α ( tef1 ) supported the description of two new species of fungi described herein as C. aurantia sp. nov. and C. vidyodayana sp. nov. Moreover, novel host-fungal association records for C. chiangmaiensis , C. falsilunata , C. lonarensis , C. plantarum , and C. pseudobrachyspora are updated herein. In addition, five species within the genus Curvularia , viz ., C. asiatica , C. geniculata , C. lunata , C. muehlenbeckiae , and C. verruculosa represent new records of fungi from Sri Lanka.
