The genus is the largest genus of the oomycetes, fungus-like members of the kingdom that also contains amoeboid (e.g., ) and plant-like (e.g., ) lifeforms. species are obligate biotrophic plant pathogens, causing high economic losses in various crops and ornamentals, including species. Several species of are used as speciality crops and medicinal plants. In this study, species parasitic on were investigated based on morphology and phylogenetic analyses using two nuclear (ITS, nrLSU) loci and one mitochondrial (2) locus. As a result of these investigations, 10 new species are added to the already known species on . Interestingly, it was found that four independent species are parasitic to , highlighting that the reliance on the host plant for pathogen determination can be misleading in . Taking this into account, morphological and phylogenetic analyses should be conducted as a prerequisite for effective quarantine regulations and phytosanitary measures. : Mu M, Choi Y-J, Kruse J, et al. 2024.

霜霉属是卵菌纲中最大的属，卵菌纲是真菌界中类似真菌的成员，该界还包含变形虫状（如 ）和植物状（如 ）的生命形式。霜霉属物种是专性活体营养型植物病原体，会给包括 物种在内的各种农作物和观赏植物造成巨大经济损失。霜霉属的几个物种被用作特色作物和药用植物。在本研究中，基于形态学以及使用两个核基因座（ITS、nrLSU）和一个线粒体基因座（2）进行的系统发育分析，对寄生于 的霜霉属物种进行了调查。这些调查结果表明，在 上，已有已知霜霉属物种的基础上又增加了10个新物种。有趣的是，发现有四个独立的物种寄生于 ，这突出表明在 中，仅依靠寄主植物来确定病原体可能会产生误导。考虑到这一点，形态学和系统发育分析应作为有效的检疫法规和植物检疫措施的先决条件进行。：Mu M，Choi Y-J，Kruse J等。2024年。单一寄主植物物种可能携带不止一种霜霉属物种——以感染车前草的霜霉属为例。《真菌学报》52：94 - 118。https://doi.org/10.3767/persoonia.2024.52.04 。
