Pucciniales(锈病真菌)是植物病原体中最大的真菌之一。它们共同感染小麦和大豆等关键作物,威胁全球粮食安全。在2010年代早期,三种锈病真菌的基因组序列被释放:Melampsoralarici-populina(杨树叶锈病真菌),普契氏菌f.sp.小麦(小麦茎锈病真菌),和条锈病f.sp.triciti(小麦条锈病或小麦黄锈病真菌)。这些基因组的可用性将锈病生物学带入了后基因组时代,引发了一系列基因组学,转录组学,在硅,和功能研究。这里,我们概述了过去10年的后基因组学研究,P.graminisf.sp.Tritici,和/或P.striiformisf.sp.Tritici.这篇小型评论特别揭示了研究社区以物种为中心的模型结构,并强调了自2014年以来针对效应物的功能研究数量的急剧增加,其中显着揭示了叶绿体作为锈病真菌靶向的中心宿主区室。这篇小型评论还讨论了其他锈病物种的基因组学促进研究,以及与全阶段锈病基因组相关的新兴后基因组研究趋势。
Pucciniales (rust fungi) are one of the largest fungal order of plant pathogens. They collectively infect key crops such as wheat and soybean, and threaten global food security. In the early 2010s, the genome sequences of three rust fungi were released: Melampsora larici-populina (the poplar leaf rust fungus), Puccinia graminis f. sp. tritici (the wheat stem rust fungus), and Puccinia striiformis f. sp. triciti (the wheat stripe rust or wheat yellow rust fungus). The availability of those genomes has forwarded rust biology into the post-genomic era, sparking a series of genomics, transcriptomics, in silico, and functional studies. Here, we snapshot the last 10 years of post-genomics studies addressing M. larici-populina, P. graminis f. sp. tritici, and/or P. striiformis f. sp. tritici. This mini-review notably reveals the model species-centered structure of the research community, and highlights the drastic increase of the number of functional studies focused on effectors since 2014, which notably revealed chloroplasts as a central host compartment targeted by rust fungi. This mini-review also discusses genomics-facilitated studies in other rust species, and emerging post-genomic research trends related to fully-phased rust genomes.
