Abstract

Ravenelia is the third largest rust genus of the order Pucciniales with more than 200 described species. It is an important rust genus that has undergone tremendous taxonomic changes. This genus produces teliospores united into a head on a compound pedicel composed of two to several hyphae with autoecious, macro-, demi- to hemi-, and, more rarely, microcyclic modes of their life cycle which provide it a unique identity and have proved helpful in the identification of the genus. The current understanding of the taxonomy, history, diversity and distribution of this genus is discussed in this paper. Both online and offline resources were searched to gather data of the published literature. The data thus obtained were analyzed for numerical and graphical summaries to provide the diversity and distribution of the genus. In addition, a phylogenetic analysis based on the ITS and nLSU DNA sequence data available in GenBank and the published literature was performed to examine the taxonomic placement of different species within the genus. The genus was reported to be distributed over 53 countries of the world. Around 51 plant genera belonging to four plant families, viz., Fabaceae, Phyllanthaceae, Asphodelaceae and Zygophyllaceae were found to be infected with these rust fungi. The phylogenetic analysis based on LSU and ITS sequence data revealed the polyphyletic nature of the genus. A table of 248 species of this genus is also provided with all information of host, distribution and cited reference that can be helpful for mycologists to find all information at one place. Future perspectives for the advancement of this genus are also discussed.

Ravenelia 属：关于分类、多样性和分布的见解

锈菌属（Ravenelia）是锈菌目（Pucciniales）中的第三大锈菌属，有 200 多个已描述的物种。它是一个重要的锈属，在分类学上经历了巨大的变化。该属产生的端孢子在由两到数个菌丝组成的复花梗上结合成一个头部，其生命周期具有自交、大交、半交和微交等模式，这些模式使其具有独特的特征，并被证明有助于该属的鉴定。本文讨论了目前对该属的分类、历史、多样性和分布的认识。本文搜索了在线和离线资源，以收集已发表文献的数据。通过对所获得的数据进行数字和图表分析，总结出该属的多样性和分布情况。此外，还根据 GenBank 中的 ITS 和 nLSU DNA 序列数据以及已发表的文献进行了系统发育分析，以研究属中不同物种的分类位置。据报道，该属分布于世界 53 个国家。发现这些锈菌感染了属于四个植物科，即豆科（Fabaceae）、菲林科（Phyllanthaceae）、天南星科（Asphodelaceae）和颧叶草科（Zygophyllaceae）的约 51 个植物属。基于 LSU 和 ITS 序列数据的系统发生分析表明，该属具有多型性。本研究还提供了一份该属 248 个物种的表格，其中包含寄主、分布和引用参考文献等所有信息，有助于真菌学家在一个地方找到所有信息。此外，还讨论了该属未来的发展前景。
