Special Issue Information

Dear Colleagues,

Edible mushrooms, well known for their high nutritional and medicinal value, have been widely cultivated across the globe. Studies involving germplasm resources, molecular markers, genetics, breeding systems, and cultivation techniques have been extensively performed over the last few decades and have greatly promoted the mushroom industry. However, both mushroom development and the formation of nutritional and medicinal characteristics are complicated systems involving gene regulatory networks and environmental stimulations. In recent years, with breakthroughs regarding high-throughput sequencing and omics, genetic transformation, gene editing technologies, etc., more and more researchers have focused on the molecular genetic mechanisms of mushroom yield and quality and have made some progress. An in-depth understanding of these mechanisms has further guided and facilitated breeding. Some studies have been carried out in the field of functional gene mapping and the marker-assisted breeding of edible mushrooms with agronomic traits.

This Special Issue focuses on the field of both basic research and technological applications in mushroom genetics and breeding. Authors are welcome to submit articles in the areas of omics analysis, gene identification, genetic engineering, marker-assisted breeding, environmental response, formation mechanisms of nutritional and medicinal value, and other related areas. Articles and reviews are both welcome.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agriculture is an international peer-reviewed open access monthly journal published by MDPI.

To improve our understanding of the selfing of G. lingzhi basidiospore monokaryons and increase the efficiency of breeding excellent strains, 52 basidiospore monokaryons were isolated from a commercial G. lingzhi strain (laboratory number P). A severe partial segregation was observed using the chi-square test, the growth rate of the monokaryotic strains was normally distributed, and colonies exhibited 5 forms. The genetic diversity of the monokaryotic strains was further demonstrated by intersimple sequence repeat (ISSR) analysis, and the similarity coefficient was in the range of 0.49–1, which was consistent with the genotype classification results. In total, 14 AxBx monokaryotic strains were randomly selected for selfing with the 1 AyBy strain when the similarity coefficient was 0.76, and a total of 14 offspring were obtained via selfing, all of which were incompatible with their parents. The traits of the selfing progenies were diverse. The mycelial growth rate, fruiting body yield, and polysaccharide, triterpene, and sterol contents were the main indices. According to the membership function value, 71.43% of the selfing progeny were super parent, and the A88 strain with the best comprehensive traits was selected. These findings prove that ISSR molecular marker-assisted breeding reduces blindness, greatly reduces workload, and improves work efficiency. Full article
