Abstract

Curvularia species exhibit a wide range of ecological roles, including plant, animal, or human pathogens, as well as epiphytes, saprophytes, or endophytes, predominantly associated with cultivated cereals. In this study, several fungal isolates with similar characteristics in the genus Curvularia were recovered from various poaceous hosts (Poales plants) in different locations in Iran during 2012‒2022. Based on the morphological characteristics and multilocus phylogeny of the translation elongation factor-1 alpha (TEF1), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and the internal transcribed spacer (ITS-rDNA) genes, the studied isolates were assigned to five species, of which Curvularia caspica, sp. nov. and C. cyperi, sp. nov. are introduced as novel species and Curvularia nodulosa and C. oryzae are new records for Iran's mycobiota. Molecular studies revealed a closer relationship between one of the studied species (Curvularia sp.) and C. frankliniae. However, due to the absence of detailed morphological characteristics for C. frankliniae, morphological comparisons were not feasible. To precisely establish their phylogenetic position, more isolates need to be analyzed. Consequently, the studied species was identified as Curvularia sp. in this study. Additionally, a new clade, "papendorfii," was established to accommodate 11 species that share common morphological characteristics and form a distinct clade in phylogenetic analyses. The morphology, habitat, distribution, and evolutionary relationships of each species with other Curvularia species were analyzed, accompanied by detailed illustrations and descriptions. This comprehensive study offers valuable insights into the diversity and distribution of Curvularia species, enhancing our understanding of fungal ecology and taxonomy.

伊朗曲霉属植物的形态和分子特征,附2个新种和2个新记录。
曲霉属具有广泛的生态作用,包括植物、动物或人类病原体,以及主要与栽培谷物相关的附生植物、腐生植物或内生植物。在这项研究中,从2012-2022年伊朗不同地点的各种Poales植物宿主(Poales植物)中恢复了几种具有相似特征的曲霉属真菌分离株。根据翻译伸长因子-1 α (TEF1)、甘油醛-3-磷酸脱氢酶(GAPDH)和内部转录间隔物(ITS-rDNA)基因的形态特征和多位点系统发育,将所研究的分离株划分为5个种,其中caspica曲霉属和cyperi曲霉属为新种,结核曲霉属和C. oryzae为伊朗真菌区系新记录。分子研究显示其中一种(Curvularia sp.)与C. frankliniae有较近的亲缘关系。然而,由于没有详细的形态学特征,因此无法进行形态学比较。为了准确地确定它们的系统发育位置,需要对更多的分离株进行分析。因此,本研究确定研究种为曲霉属(Curvularia)。此外,一个新的分支“papendorfii”被建立,它包含了11个物种,它们具有共同的形态特征,并在系统发育分析中形成了一个独特的分支。分析了各种的形态、生境、分布及其与其他种的进化关系,并附有详细的插图和描述。该研究对曲霉属真菌的多样性和分布有重要的指导意义,提高了我们对真菌生态学和分类学的认识。

期刊介绍: International in coverage, Mycologia presents recent advances in mycology, emphasizing all aspects of the biology of Fungi and fungus-like organisms, including Lichens, Oomycetes and Slime Molds. The Journal emphasizes subjects including applied biology, biochemistry, cell biology, development, ecology, evolution, genetics, genomics, molecular biology, morphology, new techniques, animal or plant pathology, phylogenetics, physiology, aspects of secondary metabolism, systematics, and ultrastructure. In addition to research articles, reviews and short notes, Mycologia also includes invited papers based on presentations from the Annual Conference of the Mycological Society of America, such as Karling Lectures or Presidential Addresses.
