Abstract

Cronartium species (Basidiomycota, Pucciniales, Melampsorineae) infect two or five-needle pines, resulting in considerable economic losses and ecological damage. Many species are considered of quarantine importance, however, precise identification is challenging due to the poorly resolved generic boundaries of Cronartium and other members in Melampsorineae, as well as species limits within the genus Cronartium. In this study, species delimitation was carried out based on morphological examination and multi-locus phylogenetic assessment using sequences of rDNA SSU-ITS-LSU regions and CO3 gene. Twenty-six species including seven new species (C. castaneae, C. mongolicum, C. murrayanae, C. myricae, C. peridiatum, C. qinlingense, C. ribistaedae), and one new combination (C. floridanum) are recognized. Cronartium arizonicum, C. comandrae, C. comptoniae, C. occidentale, and C. pyriforme are epitypified to stabilize the use of names for taxonomy and quarantine significance. In addition, 18 species were revealed for their previously unknown life cycles.
Cronartium rust (puccininiales, Cronartiaceae):种划分、多样性和寄主交替
担子菌属(Basidiomycota, puccininiales, Melampsorineae)侵染二针松或五针松,造成相当大的经济损失和生态破坏。许多物种被认为具有重要的检疫意义,然而,由于Cronartium和Melampsorineae中其他成员的属界不明确,以及Cronartium属内的物种限制,精确鉴定是具有挑战性的。本研究利用rDNA SSU-ITS-LSU区域序列和CO3基因序列,基于形态学检查和多位点系统发育评估进行物种划分。共发现26种,包括7个新种(castaneae、c.m mongolicum、c.m urrayanae、c.m myricae、c.m peridiatum、c.c qinlingense、c.m ribistaedae)和1个新组合(c.f floridanum)。为了稳定分类和检疫意义上的名称的使用,本文对克罗纳artium arizonicum、C. command、C. comptonae、C. occidentale和C. pyriforme进行了概括。此外,还发现了18种以前不为人知的生命周期。
