Toductus and T.thermophilus could reflect either the specificity of their DNA uptake systems, or habitat specificity.It was identified that the very frequent genomic rearrangements involving chromosomal and plasmid loci in Thermus genomes are moderated by NAMI-A manufacturer internal mechanisms, which pretty probably contribute for the adaptive evolution of those bacteria.Entire operons additional normally are transferred as entities, thus the rearrangements usuallyKumwenda et al.BMC Genomics , www.biomedcentral.comPage ofdo not disrupt syntenies of functionally connected genes.We didn’t find any correlation involving the price of rearrangements and acquisitions of horizontally transferred genomic islands, but an escalating trend was observed in rearrangement frequencies in extreme thermophiles.Gene exchange by transformation have been discovered to occur extra regularly between thermophilic T.scotoductus and Meiothermus in lieu of amongst the extreme thermophiles.It may be explained either by the sharing of popular habitats with moderate thermophiles, or by the truth that naked DNA fragments degrade considerably more quickly at very high temperature environments.Further fileAdditional file Tree topologies for orthologous genes.
Background The sclerotium of Lignosus rhinocerotis (Cooke) Ryvarden or Tiger milk mushroom (Polyporales, Basidiomycota) is a worthwhile folk medicine for indigenous peoples in Southeast Asia.Despite the escalating interest within this ethnobotanical mushroom, very tiny is identified in regards to the molecular and genetic basis of its medicinal and nutraceutical properties.Results The de novo assembled .Mb L.rhinocerotis genome encodes , putative genes with .of them having detectable sequence similarities to other people accessible in public databases.Phylogenetic analysis revealed a close evolutionary partnership of L.rhinocerotis to Ganoderma lucidum, Dichomitus squalens, and Trametes versicolor within the core polyporoid clade.The L.rhinocerotis genome encodes a repertoire of enzymes engaged in carbohydrate and glycoconjugate metabolism, as well as cytochrome Ps, putative bioactive proteins (lectins and fungal immunomodulatory proteins) and laccases.Other genes annotated involve these encoding important enzymes for secondary metabolite biosynthesis, such as these from polyketide, nonribosomal peptide, and triterpenoid pathways.Among them, the L.rhinocerotis genome is specifically enriched with sesquiterpenoid biosynthesis genes.Conclusions The genome content of L.rhinocerotis gives insights into the genetic basis of its reported medicinal properties also as serving as a platform to additional characterize putative bioactive proteins and secondary metabolite pathway enzymes and as a reference for comparative genomics of polyporoid fungi.
