Abstract

This study investigates the presence of mycoviruses in Antarctic fungi and elucidates their evolutionary relationships. To achieve this, we aligned mycoviral gene sequences with genomes of previously sequenced Antarctic endophytic fungi, made available by our research group and accessible via Joint Genome Institute. Our findings reveal that the most prevalent genetic regions in all endophytic fungi are homologous to Partitiviruses, Baculoviridae, and Phycodnaviridae. These regions display evidence of positive selection pressure, suggesting genetic diversity and the accumulation of nonsynonymous mutations. This phenomenon implies a crucial role for these regions in the adaptation and survival of these fungi in the challenging Antarctic ecosystems. The presence of mycoviruses in Antarctic endophytic fungi may indicate shared survival strategies between the virus and its host, shedding light on their evolutionary dynamics. This study underscores the significance of exploring mycoviruses within endophytic fungi and their contributions to genetic diversity. Future research avenues could delve into the functional implications of these conserved mycoviral genetic regions in Antarctic endophytic fungi, providing a comprehensive understanding of this intriguing association and genomic retention of viral region in fungi.

从苔藓中分离出的真菌中隐藏的南极真菌病毒宝藏:第一种基因组学方法
本研究调查了南极真菌中霉菌病毒的存在,并阐明了它们之间的进化关系。为此,我们将霉菌病毒基因序列与之前测序的南极内生真菌基因组进行了比对,这些基因组由我们的研究小组提供,可通过联合基因组研究所访问。我们的研究结果表明,所有内生真菌中最普遍的基因区域都与 Partitiviruses、Baculoviridae 和 Phycodnaviridae 同源。这些区域显示出正向选择压力,表明遗传多样性和非同义突变的积累。这一现象表明,这些区域对这些真菌在充满挑战的南极生态系统中的适应和生存起着至关重要的作用。南极内生真菌中霉菌病毒的存在可能表明病毒与其宿主共享生存策略,从而揭示了它们的进化动态。这项研究强调了探索内生真菌中的霉菌病毒及其对遗传多样性的贡献的重要性。未来的研究途径可以深入探讨南极内生真菌中这些保守的真菌病毒基因区域的功能意义,从而全面了解真菌中这种有趣的关联和病毒区域的基因组保留。

期刊介绍: The Journal of Basic Microbiology (JBM) publishes primary research papers on both procaryotic and eucaryotic microorganisms, including bacteria, archaea, fungi, algae, protozoans, phages, viruses, viroids and prions. Papers published deal with: microbial interactions (pathogenic, mutualistic, environmental), ecology, physiology, genetics and cell biology/development, new methodologies, i.e., new imaging technologies (e.g. video-fluorescence microscopy, modern TEM applications) novel molecular biology methods (e.g. PCR-based gene targeting or cassettes for cloning of GFP constructs).
