锈菌属是锈菌的第三大属,寄生于大量豆科灌木和树木,主要分布在亚热带和热带地区。利用nc 28S rDNA和co3序列对该属的分子系统发育进行了分析,并特别关注了南非的ravenelia代表。近年来,我们收集了大量的金合欢标本,主要来自金合欢属和塞内加尔属的金合欢种。利用光镜和扫描电镜对其形态特征进行了广泛的研究。这些分析解决了几个得到充分支持的系统发生群。通过将这些群体与它们的形态和生命周期特征联系起来,就有可能从它们的进化生态学和生物地理学的角度来解释结果。由于假设趋同进化,先前用于定义拉文氏亚种群的几个特征被发现具有误导性。然而,寄主关联、诱导特殊瘿的能力以及两层原孢子细胞的发育成为推断单系群体的有用标准。发现并描述了6个新属。此外,有5种为南非的新报告,2个分类群的物种描述进行了修订,并出现了一种新的r宿主报告。inornata。
The genusRaveneliarepresents the third largest genus of rust fungi and parasitizes a great number of leguminous shrubs and trees, mainly in the subtropics and tropics. Molecular phylogenetic analyses of this genus using nc 28S rDNA andCO3sequences are presented with a special focus on South African representatives ofRavenelia. Many of the specimens had been collected by us in recent years, mainly from acacia species of the generaVachelliaandSenegalia. Morphological characters were extensively studied using light microscopy and scanning electron microscopy. The analyses resolved several well-supported phylogenetic groups. By linking these groups to their morphology and life cycle characteristics, it was possible to interpret the outcomes in terms of their evolutionary ecology and biogeography. Several characters previously used to define subgeneric groups withinRaveneliawere found to be misleading because of assumed convergent evolution. However, host associations, the ability to induce aecial galls as well as the development of two-layered probasidial cells emerged as useful criteria for inferring monophyletic groups. Six novelRaveneliaspecies were discovered and described. Furthermore, five species represent new reports for South Africa, species descriptions were emended for two taxa, and a new host report emerged forR. inornata.
