In the last two decades, studies on plant biomass-degrading fungi have remarkably increased to understand and reveal the underlying molecular mechanisms responsible for their life cycle and wood-decaying abilities. Most of the plant biomass-degrading fungi reported till date belong to basidiomycota or ascomycota phyla. Thus, very few studies were conducted on fungi belonging to other divisions. Recent sequencing studies have revealed complete genomic sequences of various fungi. Our present study is focused on understanding the plant biomass-degrading potentials, by retrieving genome-wide annotations of 56 published fungi belonging to Glomeromycota, Mucoromycota, Zoopagomycota, Blastocladiomycota, Chytridiomycota, Neocallimastigomycota, Microsporidia and Cryptomycota from JGI-MycoCosm repository. We have compared and analyzed the proteomic annotations, especially CAZy, KOG, KEGG and SM clusters by separating the proteomic annotations into lignin-, cellulose-, hemicellulose-, pectin-degrading enzymes and also highlighted the KEGG, KOG molecular mechanisms responsible for the metabolism of carbohydrates (lignocellulolytic pathways of fungi), complex organic pollutants, xenobiotic compounds, biosynthesis of secondary metabolites. However, we strongly agree that studying genome-wide distributions of fungal CAZyme does not completely corresponds to its biomass-degrading ability. Thus, our present study can be used as preliminary materials for selecting ideal fungal candidate for the degradation and conversion of plant biomass components, especially carbohydrates to bioethanol and other commercially valuable products.

对公开可用的非Dikarya真菌蛋白质组进行系统综述，以了解其植物生物质降解和生物修复潜力

在过去的二十年中，对植物生物质降解真菌的研究显着增加，以了解和揭示影响其生命周期和木材腐烂能力的潜在分子机制。迄今报道的大多数降解植物生物质的真菌均属于担子菌或门生子囊菌。因此，很少有关于属于其他部门的真菌的研究。最近的测序研究已经揭示了各种真菌的完整基因组序列。我们目前的研究重点是通过检索56种已发表的真菌的基因组范围注释来了解植物生物质的降解潜力，这些真菌分别属于球孢菌，毛霉菌，动杆菌，Blastocladiomycota，Chytridiomycota，Neocallimastigomycota，Microsporidia和隐霉菌从JGI-MycoCosm存储库中。我们通过将蛋白质组注释分解为降解木质素，纤维素，半纤维素，果胶的酶，比较并分析了蛋白质组注释，尤其是CAZy，KOG，KEGG和SM簇，并重点介绍了负责代谢的KEGG，KOG分子机制碳水化合物（真菌的木质纤维素分解途径），复杂的有机污染物，异种生物化合物，次生代谢产物的生物合成。但是，我们强烈同意研究真菌CAZyme的全基因组分布并不完全对应于其降解生物质的能力。因此，我们目前的研究可以用作初步材料，为植物生物质组分的降解和转化选择理想的真菌候选物，
