A Comprehensive Assessment of Ultraviolet-Radiation-Induced Mutations in Using Whole-Genome Resequencing.

Nucleotide substitutions have played an important role in molecular evolution, and understanding their dynamics would contribute to genetic studies. Related research with defined DNA sequences lasted for decades until whole-genome sequencing arose. UV radiation (UVR) can generate base changes and other genetic variations in a short period of time, so it would be more meaningful to explore mutations caused by UVR from a genomic perspective.

Transcriptome Profiling Reveals Candidate Genes Related to Stipe Gradient Elongation of .

Stipe gradient elongation is an important and remarkable feature in the development of most mushroom fruiting bodies. However, its molecular mechanism has rarely been described. Here, the decreasing trend of stipe elongation and increasing trend of cell length in a gradient from the top to the base of the stipe were determined in a model basidiomycete mushroom: .

Comparative Proteomics Study on the Postharvest Senescence of .

is difficult to store after harvest, which restricts the production and circulation of fruiting bodies. Low-temperature storage is the traditional storage method used for most edible fungi. However, undergoes autolysis at low temperatures.

Reactive Oxygen Species Distribution Involved in Stipe Gradient Elongation in the Mushroom .

The mushroom stipe raises the pileus above the substrate into a suitable position for dispersing spores. The stipe elongates at different speeds along its length, with the rate of elongation decreasing in a gradient from the top to the base. However, the molecular mechanisms underlying stipe gradient elongation are largely unknown.

Comparative Transcriptomics of Suggests a High CO Concentration Inhibits Early Pileus Expansion by Decreasing Cell Division Control Pathways.

Carbon dioxide is commonly used as one of the significant environmental factors to control pileus expansion during mushroom cultivation. However, the pileus expansion mechanism related to CO is still unknown. In this study, the young fruiting bodies of a popular commercial mushroom were cultivated under different CO concentrations.

The NADPH oxidase in Volvariella volvacea and its differential expression in response to mycelial ageing and mechanical injury.

NADPH oxidases are enzymes that have been reported to generate reactive oxygen species (ROS) in animals, plants and many multicellular fungi in response to environmental stresses. Six genes of the NADPH oxidase complex components, including vvnoxa, vvnoxb, vvnoxr, vvbema, vvrac1 and vvcdc24, were identified based on the complete genomic sequence of the edible fungus Volvariella volvacea. The number of vvnoxa, vvrac1, vvbema and vvcdc24 transcripts fluctuated with ageing, and the gene expression patterns of vvnoxa, vvrac1 and vvbema were significantly positively correlated.

A hydrophobin gene, Hyd9, plays an important role in the formation of aerial hyphae and primordia in Flammulina filiformis.

Flammulina filiformis is an edible fungus that is largely cultivated and widely consumed around the world. The quantity and quality of the primordia, which gives rise to the fruiting body, affects its production efficiency. Hydrophobins are involved in the formation of the fruiting body of macrofungi.
