摘要

锈菌是最大的植物病原菌群之一,存在于苔藓、蕨类植物到高级单子叶植物和双子叶植物上。到目前为止,已经报道了7个亚目和18个科,但最近的系统发育研究显示,几个形态上确定的亚目和科,特别是在黑鹳鸟科中,存在着半聚或多聚现象。本研究基于黑孢菌科16属160种(Chrysomyxa、Cerospora、Coleopuccinia、Coleosporium、Cronartium、Hylospora、Melampsora、Melampsorella、Melampsoridium、Milesina、Naohidemyces、Pucciniastrum、Quasipucciniastrum、Rossmanomyces、Thekopsora、Uredinopsis)的rDNA序列,构建了一个完整的系统发育框架。我们的系统发育推断表明13个属是单系的,具有很强的支撑力,而puccininiastrum则明显是多系的。因此,一个新的属Nothopucciniastrum被建立并从Pucciniastrum中分离出来,并提出了10个新的组合。在科水平上,本研究进一步证明了将产生孢子的结构形态(担子孢子、精子、无孢子、脲孢子和端孢子)应用于高阶分类的重要性,而传统上应用的孢子形态(担子孢子、精子、无孢子、脲孢子和端孢子)则表现出较晚的分化特征,更适合于属和种水平的分类。根据系统发育和形态上的差异,提出了Hyalopsoraceae、Nothopucciniastraceae和Thekopsoraceae三个新科,并根据系统发育关系对puccinia亚目进行了进一步修订。

Applying early divergent characters in higher rank taxonomy of Melampsorineae (Basidiomycota, Pucciniales).

Rust fungi in the order Pucciniales represent one of the largest groups of phytopathogens, which occur on mosses, ferns to advanced monocots and dicots. Seven suborders and 18 families have been reported so far, however recent phylogenetic studies have revealed para- or polyphyly of several morphologically defined suborders and families, particularly in Melampsorineae. In this study, a comprehensive phylogenetic framework was constructed based on a molecular phylogeny inferred from rDNA sequences of 160 species belonging to 16 genera in Melampsorineae (i.e. Chrysomyxa, Cerospora, Coleopuccinia, Coleosporium, Cronartium, Hylospora, Melampsora, Melampsorella, Melampsoridium, Milesina, Naohidemyces, Pucciniastrum, Quasipucciniastrum, Rossmanomyces, Thekopsora, Uredinopsis). Our phylogenetic inference indicated that 13 genera are monophyletic with strong supports, while Pucciniastrum is apparently polyphyletic. A new genus, Nothopucciniastrum was therefore established and segregated from Pucciniastrum, with ten new combinations proposed. At the family level, this study further demonstrates the importance of applying morphologies of spore-producing structures (basidia, spermogonia, aecia, uredinia and telia) in higher rank taxonomy, while those traditionally applied spore morphologies (basidiospores, spermatia, aeciospores, urediniospores and teliospores) represent later diverged characters that are more suitable for the taxonomy at generic and species levels. Three new families, Hyalopsoraceae, Nothopucciniastraceae and Thekopsoraceae were proposed based on phylogenetic and morphological distinctions, towards a further revision of Pucciniales in line with the phylogenetic relationships.
