Abstract
We describe Myxotrichum persicum sp. nov. as a seed endophyte of Aegilops triuncialis in Lorestan province of Iran, using morphological traits and sequences of the internal transcribed spacer regions 1 and 2 including the intervening 5.8S nuclear ribosomal DNA (ITS) and partial nuclear 28S ribosomal DNA (LSU) regions. Myxotrichum persicum is differentiated from its closest relative, M. deflexum, by possessing smaller ascomata bearing much shorter, usually unbranched appendages, and smaller, ellipsoidal to fusiform, smooth-walled ascospores. Based on morphology and the multilocus phylogeny of ITS, LSU, MCM7 and RPB1, we herein propose to combine two species of Malbranchea, namely M. circinata and M. flavorosea, into the genus Myxotrichum as Myxotrichum circinatum and M. flavoroseum, respectively.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
