The fish fungal pathogen (Saprolegnia) belonging to heterokonts group, causing Saprolegniosis, received considerable attention among all the fungal pathogens of fish. The pathogen is widely distributed to aquatic habitat and is an economically important member of the class Oomycetes. The genus comprises of opportunistic biotrophic or parasitic pathogens of fish and relevant aquatic organisms. The atrocities of pathogen account for few million dollar losses to the aquaculture production worldwide. It has also remained linked to the cosmopolitan decline in wild fish stocks, amphibian, and crustacean populations. In order to overcome the burden of the disease, there is a crucial need to develop strategies for the effective management of Saprolegniosis. However, in order to manage the disease burden, there is a basic requirement to understand the phylogeny, taxonomy and molecular mechanism involved in the disease progression. With the tremendous advent and escalation in the fungal genome sequencing projects which helped in understanding the novelties of many fungal taxa so far, there is still dearth in the molecular information available on Saprolegnia spp. Owing to the scarcity of the cumulative information pool, there arises a need to assemble phylogenetic, taxonomic and molecular data of Saprolegniales along with their transcriptomic data from various databases available, so that the consolidated information be made accessible to the researchers. In the above context, this review shall serve as an important information resource on the overall biological aspects of Saprolegnia spp., and a way forward to tackle this pathogen efficiently. Various genomic and transcriptomic studies discussed shall enlighten the understanding of Saprolegnia pathogenesis mechanisms and subsequently benefit in framing strategies to contain the pathogen efficiently.

腐烂症(Oomycota; Stramnipila)(鱼类的重要真菌病原体)的综合,经典和分子表征方法

属于腐殖菌病的杂菌类鱼类真菌病原体(Saprolegnia)在鱼类的所有真菌病原体中引起了极大的关注。该病原体广泛分布于水生栖息地,是卵菌纲的经济重要成员。该属包括鱼类和相关水生生物的机会性生物营养或寄生病原体。病原体的暴行造成全球水产养殖生产损失数百万美元。它还与野生鱼类种群,两栖动物和甲壳类种群的世界性减少联系在一起。为了克服疾病的负担,迫切需要开发有效治疗腐生病的策略。但是,为了控制疾病负担,有基本的要求来了解疾病进展涉及的系统发育,分类学和分子机制。随着真菌基因组测序项目的巨大兴起和升级,迄今为止有助于理解许多真菌类群的新颖性,目前尚缺乏分子生物学信息。菌属。由于累积信息库的稀缺性,因此需要将腐霉菌的系统发育,分类学和分子学数据与来自各种可用数据库的转录组数据进行汇总,以便使研究人员可以访问合并后的信息。在上述背景下,本次审查应作为对整体生物学方面的重要信息资源的水霉属,和前进的方式来有效地对付这种病菌。所讨论的各种基因组和转录组研究将启发人们对腐烂症发病机理的理解,并随后从成帧策略中受益,以有效地遏制病原体。
