锈菌属有 4000 种，是锈菌中最大的属，也是破坏性植物病原性锈菌属之一，据报道，锈菌可使农业和非农业植物感染严重疾病。双细胞冬孢子的存在是这些锈菌的主要特征之一，将它们与锈菌属（锈菌的另一个最大属）区别开来。在本研究中，概述了锈菌属锈菌的一般分类学和生态学的当前知识。除了该属对农业和非农业植物的威胁外，还介绍了该属的分子鉴定状况以及更新的物种数量及其在 21 世纪的现状。此外，基于 GenBank 中提供的 ITS 和 LSU DNA 序列数据以及已发表的文献进行了系统发育分析，以检查柄锈菌的属间关系。获得的结果揭示了柄锈菌的全球分布。与其他国家相比，本世纪亚洲国家的研究出版物出现了合理增长。据观察，菊科和禾本科植物是 21 世纪感染最严重的植物。LSU 和 ITS 序列数据的系统发育研究揭示了柄锈菌的多系性质。此外，NCBI 数据库中存在的太短、太长和不完整的序列表明需要进行广泛的基于 DNA 的分析，以更好地了解柄锈菌的分类位置。

Insights into Diversity, Distribution, and Systematics of Rust Genus Puccinia

Puccinia, which comprises 4000 species, is the largest genus of rust fungi and one of the destructive plant pathogenic rust genera that are reported to infect both agricultural and nonagricultural plants with severe illnesses. The presence of bi-celled teliospores is one of the major features of these rust fungi that differentiated them from Uromyces, which is another largest genus of rust fungi. In the present study, an overview of the current knowledge on the general taxonomy and ecology of the rust genus Puccinia is presented. The status of the molecular identification of this genus along with updated species numbers and their current statuses in the 21st century are also presented, in addition to their threats to both agricultural and nonagricultural plants. Furthermore, a phylogenetic analysis based on ITS and LSU DNA sequence data available in GenBank and the published literature was performed to examine the intergeneric relationships of Puccinia. The obtained results revealed the worldwide distribution of Puccinia. Compared with other nations, a reasonable increase in research publications over the current century was demonstrated in Asian countries. The plant families Asteraceae and Poaceae were observed as the most infected in the 21st century. The phylogenetic studies of the LSU and ITS sequence data revealed the polyphyletic nature of Puccinia. In addition, the presences of too short, too lengthy, and incomplete sequences in the NCBI database demonstrate the need for extensive DNA-based analyses for a better understanding of the taxonomic placement of Puccinia.
