Abstract

ABSTRACTShearia belongs to the Longiostiolaceae (Pleosporales, Dothideomycetes) and is typified by S. formosa. Previously, Shearia species were reported by their asexual morph, and here we introduce the first sexual morph for Shearia. We also provide the sexual-asexual linkage of S. formosa with two new host records from Magnolia sprengeri and Michelia alba from China based on morpho-molecular analyses. The sexual morph of S. formosa is characterised by having perithecial ascomata with an erumpent ostiole, cellular pseudoparaphyses and asci embedded in a gelatinous matrix, short pedicellate asci with an ocular chamber, and transversely and vertically septate spores surrounded by a thick mucilaginous sheath. Our S. formosa isolates clustered with other authentic strains of S. formosa based on maximum parsimony, maximum likelihood, and Bayesian inference analyses of the combined sequence data of 28S ribosomal RNA (LSU), 18S small subunit rDNA (SSU), RNA polymerase II second largest subunit (rpb2), and the translation elongation factor 1-alpha gene (tef).KEYWORDS: Asexual morphmulti-loci phylogenyPleosporalessexual morphShearia formosatwo new records AcknowledgementsThe authors thank the National Research Council of Thailand (NRCT) grant “Total fungal diversity in a given forest area with implications towards species numbers, chemical diversity and biotechnology” (grant no.

揭示中国台湾雪梨属植物的全型及新寄主记录

摘要羊角菌属长孢菌科(多孢菌门，多孢子菌门)，以S. formosa为代表。在此，我们介绍了Shearia的第一个有性形态。通过形态分子分析，我们还从中国的白玉兰和白含莲两种新寄主记录中发现了台湾沙蚕的性-无性联系。台湾丝虫病的性形态的特征是:包皮囊胞具有隆起的口孔，细胞假性麻痹和囊胞嵌在胶状基质中，短有花梗的囊胞有眼室，孢子被厚的粘液鞘包围，横向和纵向分开。基于28S核糖体RNA (LSU)、18S小亚基rDNA (SSU)、RNA聚合酶II第二大亚基(rpb2)和翻译延伸因子1- α基因(tef)的组合序列数据，我们的台湾血吸虫分离株与其他台湾血吸虫菌株聚类，并进行了最大简约性、最大似然和贝叶斯推断分析。关键词:无性形态多位点系统发育多孢子性形态台湾沙蚤两项新记录致谢作者感谢泰国国家研究委员会(NRCT)资助“给定森林地区真菌总多样性与物种数量、化学多样性和生物技术的关系”(资助号:no. 5)。N42A650547)。Ashani D.
