Abstract

Alternaria, a genus of ascomycetes, comprises major plant pathogens, saprobes and are common allergens to humans. There are more than 360 accepted species in the genus, which are currently divided into 29 sections. This paper aims to elaborate the taxonomy of Alternaria with multi-locus phylogenetic trees derived by analyses of a concatenated DNA sequence dataset consisting of ITS, LSU, TEF1-α, RPB2, GAPDH and Alt-a1 loci. Eighteen new species viz. Alternaria arctoseptata, A. arundinis,A. baoshanensis, A. breviconidiophora,A. brevirostra,A. ellipsoidialis,A. eupatoriicola,A. falcata,A. lathyri, A. macilenta,A. macroconidia,A. minimispora,A. nodulariconidiophora, A. oblongoellipsoidea, A. orobanches, A. phragmiticola,A. phytolaccae and A. salicicola are introduced and classified in sect. Alternaria, sect. Infectoriae, sect. Porri and sect. Radicina. Alternaria alternata andA. doliconidium are also described herein with new host and geographical records, in China, Italy, and Thailand. This study further explores the utility of divergent time estimates to gain additional insights into the evolutionary relationships of Alternaria in Pleosporales.

交替;:物种限制、进化、多位点系统发育和分类的最新进展

交替子囊菌是子囊菌的一属，由主要的植物病原体、物种和人类常见的过敏原组成。该属有360多种被认可的物种，目前分为29个科。本文旨在利用ITS、LSU、TEF1-α、RPB2、GAPDH和Alt-a1位点组成的DNA序列数据集，建立多位点系统发育树，阐述Alternaria的分类。新种18种，即:竹竹竹属、竹竹竹属、竹竹竹属。宝山，A. breviconidiophora,A.;brevirostra,。ellipsoidialis,。eupatoriicola,。falcata,。lathyri, A. macilenta,A。macroconidia,。minimispora,。长椭圆形，长圆形，长圆形，长圆形，长圆形，长圆形。介绍了植物芽孢杆菌科和水杨芽孢杆菌属植物芽孢杆菌属植物芽孢杆菌属植物芽孢杆菌属植物芽孢杆菌属植物芽孢杆菌属植物芽孢杆菌属植物芽孢杆菌属植物芽孢杆菌属植物芽孢杆菌属植物芽孢杆菌属植物芽孢杆菌属。互生植物。本文还介绍了在中国、意大利和泰国的新宿主和地理记录。本研究进一步探索了不同时间估计的效用，以获得更多关于多孢目交替性进化关系的见解。
