In nature; , also known as winter mushrooms, vary in the color of their fruiting bodies, from black, yellow, pale yellow, or beige to white. The purpose of this study was to compare the genome sequences of different colored strains of and to identify variations in the genes associated with fruiting body color. Comparative genomics of six strains revealed 70 white-strain-specific variations, including single nucleotide polymorphisms (SNPs) and insertions/deletions (indels), in the genome sequences.

White strains of are more difficult to cultivate than are brown strains; therefore, new white strain breeding strategies are required. Accordingly, we constructed the genetic map of with 1996 SNP markers on 11 linkage groups (LGs) spanning 1380.49 cM.

is a popular edible mushroom that is cultivated worldwide. Due to its secondary homothallic nature, cultivated strains have low genetic diversity, and breeding novel strains is challenging. The aim of this study was to investigate the genetic diversity and population structure of globally collected .

, commonly known as the button mushroom, is widely cultivated throughout the world. To breed new strains with more desirable traits and improved adaptability, diverse germplasm, including wild accessions, is a valuable genetic resource. To better understand the genetic diversity available in and identify previously unknown diversity within accessions, a phylogenetic analysis of 360 spp.

species are commercially essential mushrooms and widely cultivated throughout the world. The production of mushrooms alone accounts for around 25% of that total cultivated mushrooms globally. In America and Europe, species are considered specialty mushrooms, whereas, in Korea, their cultivation is economically profitable, and it is one of the highly consumed species.

The white button mushroom () is one of the most widely cultivated species of edible mushroom. Despite its economic importance, relatively little is known about the genetic diversity of this species. Illumina paired-end sequencing produced 43,871,558 clean reads and 69,174 contigs were generated from five offspring.

Background: Hypsizygus marmoreus (Beech mushroom) is a popular ingredient in Asian cuisine. The medicinal effects of its bioactive compounds such as hypsin and hypsiziprenol have been reported, but the genetic basis or biosynthesis of these components is unknown.

Results: In this study, we sequenced a reference strain of H.

Background: Mating-type loci of mushroom fungi contain master regulatory genes that control recognition between compatible nuclei, maintenance of compatible nuclei as heterokaryons, and fruiting body development. Regions near mating-type loci in fungi often show adapted recombination, facilitating the generation of novel mating types and reducing the production of self-compatible mating types. Compared to other fungi, mushroom fungi have complex mating-type systems, showing both loci with redundant function (subloci) and subloci with many alleles.

The process of biodegradation in lingo-cellulosic materials is critically relevant to biospheric carbon. The study of this natural process has largely involved laboratory investigations, focused primarily on the biodegradation and recycling of agricultural by-products, generally using basidiomycetes species. In order to collect super white rot fungi and evaluate its ability to degrade lingo-cellulosic material, 35 fungal strains, collected from forests, humus soil, livestock manure, and dead trees, were screened for enzyme activities and their potential to decolorize the commercially used Poly-R 478 dye.

A mesophilic bacterium, strain 15-52(T), was isolated from the rhizosphere of Chinese cabbage (Brassica campestris). On the basis of phenotypic and genotypic characteristics, the bacterium was identified as representing a novel species belonging to the genus Pedobacter. The strain is non-flagellated, non-spore-forming and grows at temperatures in the range 1-37 degrees C.
