The complete mitochondrial genome of Engyodontium album and comparative analyses with Ascomycota mitogenomes

Abstract

Engyodontium album is a widespread pathogen that causes different kinds of dermatoses and respiratory tract diseases in humans and animals. In spite of its perniciousness, the basic genetic and molecular background of this species remains poorly understood. In this study, the mitochondrial genome sequence of E. album was determined using a high-throughput sequencing platform. The circular mitogenome was found to be 28,081 nucleotides in length and comprised of 17 protein-coding genes, 24 tRNA genes, and 2 rRNA genes. The nucleotide composition of the genome was A+T-biased (74.13%). Group-II introns were found in the nad1, nad5, and cob genes. The most frequently used codon of protein-coding genes was UAU. Isoleucine was identified as the most common amino acid, while proline was the least common amino acid in protein-coding genes. The gene-arrangement order is nearly the same when compared with other Ascomycota mitogenomes. Phylogenetic relationships based on the shared protein-coding genes revealed that E. album is closely related to the Cordycipitaceae family, with a high-confidence support value (100%). The availability of the mitogenome of E. album will shed light on the molecular systematic and genetic differentiation of this species.

The complete mitochondrial genome of the Chan‐hua fungus Isaria cicadae: a tale of intron evolution in Cordycipitaceae

“…To date, mitogenomes of only nine species in Cordycipitaceae have been documented. These include Akanthomyces muscarius (NC_004514) (Kouvelis et al, 2004), Beauveria bassiana (NC_010652) (Xu et al, 2009), Beauveria brongniartii (NC_011194) (Ghikas et al, 2010), Beauveria caledonica (NC_030636), Beauveria malawiensis (NC_030635), Beauveria pseudobassiana (NC_022708; Oh et al, 2014), C. militaris (NC_022834; Sung, 2015), Lecanicillium saksenae (NC_028330; Xin et al, 2017) and Parengyodontium album (NC_032302; Yuan et al, 2017).…”

An Insight into Mitochondrial Genomes of Trichoderma Afroharzianum Strains: A Comparative and Evolutionary Analysis

“…MW525445). The observed variation in mitogenome size among both Trichoderma species and the other members of the Hypocreales order reported to date may be mainly attributable to the differences in length and number of introns, homing endonucleases and putative ORFs (Fonseca et al, 2020;Ren et al, 2021;Yuan et al, 2017;Zhang et al, 2015). However, the mitogenome architectures of T. afroharzianum were closely consistent with those of previously reported Trichoderma mitogenomes (Chung et al, 2022;Fonseca et al, 2020;Kwak, 2021Kwak, , 2020Li et al, 2021;Medina et al, 2020;Wallis et al, 2022), comprising 14 core PCGs, 22 tRNAs, two rRNAs, one gene encoding the ribosomal protein S3 and three or four genes including conserved domains for the homing endonucleases (HEGs; GIY-YIG type and LAGLIDADG type) (Fig.…”

The Gene Rearrangement, Loss, Transfer, and Deep Intronic Variation in Mitochondrial Genomes of Conidiobolus

“…In general, mitogenomic introns are highly similar and homologous in the same Pcl ( Ferandon et al, 2010 ) and have an implication for inferring fungal evolution ( Sandor et al, 2018 ). Besides the above characteristics, the codon usage, repetitive elements, and tRNA types have also been used to evaluate the evolutionary dynamics of the fungal mitogenomes ( Yuan et al, 2017 ; Abboud et al, 2018 ; Li Q. et al, 2020 , Li et al, 2021 ). Mitochondrial genomes are inherited by a single parent and have a higher number of copies, causing a faster evolution than nuclear ( Ballard and Whitlock, 2004 ; Pantou et al, 2006 ; Cameron, 2014 ).…”
