Abstract

Rhizopus delemar, an opportunistic fungal pathogen, causes a highly fatal disease, mucormycosis. Spore germination is a crucial mechanism for disease pathogenesis. Thus, exploring the molecular mechanisms of fungal germination would underpin our knowledge of such transformation and, in turn, help control mucormycosis. To gain insight into the developmental process particularly associated with cell wall modification and synthesis, weighted gene co-expression network analysis (WGCNA) was performed including both coding and non-coding transcripts identified in the current study, to find out the module of interest in the germination stages. The module-trait relationship identified a particular module to have a high correlation only at the resting phase and further analysis revealed the module to be enriched for protein phosphorylation, carbohydrate metabolic process, and cellular response to stimulus. Moreover, co-expression network analysis of highly connected nodes revealed cell wall modifying enzymes, especially those involved in mannosylation, chitin-glucan crosslinking, and polygalacturonase activities co-expressing and interacting with the novel lncRNAs among which some of them predicted to be endogenous target mimic (eTM) lncRNAs. Hence, the present study provides an insight into the onset of spore germination and the information on the novel non-coding transcripts with key cell wall–related enzymes as potential targets against mucormycosis.
发芽致毛霉病的delemrhizopus萌发lncRNA鉴定及加权基因共表达网络分析
delemar根霉是一种机会性真菌病原体,引起一种高度致命的疾病——毛霉病。孢子萌发是疾病发病的重要机制。因此,探索真菌萌发的分子机制将巩固我们对这种转化的认识,进而有助于控制毛霉病。为了深入了解与细胞壁修饰和合成相关的发育过程,我们进行了加权基因共表达网络分析(WGCNA),包括当前研究中鉴定的编码和非编码转录本,以找出萌发阶段感兴趣的模块。模块-性状关系确定了一个特定模块仅在静息期具有高相关性,进一步分析表明该模块在蛋白质磷酸化、碳水化合物代谢过程和细胞对刺激的反应中富集。此外,高连接节点的共表达网络分析显示,细胞壁修饰酶,特别是涉及甘露糖基化,几丁质-葡聚糖交联和聚半乳糖醛酸酶活性的酶,与新型lncRNAs共表达和相互作用,其中一些被预测为内源性靶模拟(eTM) lncRNAs。因此,本研究提供了孢子萌发的开始和新的非编码转录物的信息,关键细胞壁相关酶作为毛霉病的潜在靶点。
