Abstract

spp. are important pathogens of citrus that cause dieback of branches and postharvest disease. Globally, several species of have been identified as causing anthracnose of citrus. One hundred and sixty-eight isolates were collected from anthracnose symptoms on citrus stems, leaves, and fruit from Victoria, New South Wales, and Queensland, and from State herbaria in Australia. sp. nov., , , , and were identified using multi-gene phylogenetic analyses based on seven genomic loci (ITS, , , , , , and ) in the gloeosporioides complex and five genomic loci (ITS, , , , and ) in the boninense complex, as well as morphological characters. Several isolates pathogenic to chili (), previously identified as , formed a clade with the citrus isolates described here as sp. nov. The spore shape and culture characteristics of the chili and citrus isolates of were similar and differed from those of . This is the first report of isolated from citrus and the first detection of and associated with citrus anthracnose in Australia.

摘要

某些物种是柑橘的重要病原体，可导致枝条枯死和采后病害。在全球范围内，已鉴定出几种可引起柑橘炭疽病的物种。从维多利亚州、新南威尔士州和昆士兰州的柑橘茎、叶和果实上的炭疽病症状以及澳大利亚的州植物标本馆收集了168株分离株。基于盘长孢状炭疽菌复合体中的七个基因组位点（ITS、、、、、、和）以及邦宁炭疽菌复合体中的五个基因组位点（ITS、、、、和），利用多基因系统发育分析以及形态特征，鉴定出了新种、、、和。一些先前被鉴定为的对辣椒致病的分离株，与这里描述为新种的柑橘分离株形成了一个分支。辣椒和柑橘分离株的孢子形状和培养特征相似，与的不同。这是首次从柑橘中分离出的报道，也是在澳大利亚首次检测到与柑橘炭疽病相关的和。
