Summary: This study investigated the mating type determination in Closterium and identified CpMinus1 as the major determinant for mt- phenotype. Functional analysis showed that CpMinus1 is a divergent transcription factor specifically expressed during gamete differentiation. Introduction of CpMinus1 into mt+ strains converted them to mt- phenotype, while CpMinus1-knockout mt- strains exhibited the mt+ phenotype.

Summary: Fungi in the genus Malassezia, which are commonly found on the skin of humans and other warm-blooded animals, have been linked to skin diseases and systemic disorders. Analysis of Malassezia genomes suggests that their ability to adapt to the skin microenvironment is directly influenced by their genetic makeup. Despite the absence of observed sexual reproduction, the presence of mating/meiotic genes suggests a potential for sexual reproduction in Malassezia. The arrangement of mating type loci in Malassezia has been found to be different from other basidiomycetes, indicating an ancestral state of the genus.

Summary: In this study, the genetic structure and diversity of MAT loci in the tetrapolar system of Hypsizygus marmoreus were analyzed. The HD loci contained conserved gene order but variable gene content, classified into four haplotypes. Pheromone/pheromone receptor genes consisted of three pheromone receptors, three pheromones, and two pheromone receptor-like genes. The mating genes in H. marmoreus acted as switches for mating processes, with higher expression levels in compatible strains compared to homonuclear/homokaryotic strains.

Summary: This study compares the genetic differences between heterothallic and unisexual species in the Huntiella genus and finds significant differences in the genes governing sexual traits. Unisexual species do not rely on a mating partner recognition system like heterothallic species do. These results not only provide clues to understanding the mechanism of unisexual reproduction in the Huntiella genus, but also offer broader insights into the sexual reproduction and mating strategies of fungi.

Summary: The genetic regulation of Colletotrichum sexual reproduction deviate from the typical paradigm of Ascomycota and is not well understood. This study characterized the sexual behaviors of different strain types and identified molecular mechanisms underlying the process. The presence of both cross-fertilized and self-fertilized perithecia within the mating line was confirmed, shedding light on the unique sexual enhancement in Colletotrichum fungi.

Summary: This study reveals the complexity of sexual regulation in Colletotrichum fungi, as the importance of pheromone receptors and their cognate pheromones varies. The gene-deletion mutants of C. fructicola showed that PRE1 and PRE2 genes coordinate the mating of this species by recognizing novel signal molecules, while PPG1 and PPG2 genes have no effect on sexual compatibility and development.

Summary: The study provides evidence for the evolution of xyloglucan (XyG) in charophyte algae, showcasing the discovery of orthologs responsible for XyG production and the structural elucidation of XyG in various CGA. Additionally, the presence of xyloglucan fucosylation in Mesotaenium caldariorum suggests a late evolutionary elaboration of XyG structure.

Summary: The study investigates the genetic basis of homothallism in Thielaviopsis cerberus, the only known self-fertile species within this genus. By analyzing the structure and gene content of the mating-type locus, the study reveals the mechanisms underlying genetic conversion processes, and demonstrates the structural flexibility of mating-type loci among different species.

Summary: This study indirectly investigates the potential role of sexual reproduction in the pathogenic fungus Plenodomus biglobosus, which causes blackleg disease in oilseed rape. The mating types of P. biglobosus in China are unbalanced, indicating predominantly asexual reproduction. These findings are important for improving the understanding of blackleg disease, particularly in China.

Summary: In this study, a rapid LAMP assay was developed to detect the mating type of Villosiclava virens, the causal agent of rice false smut. The LAMP assay showed high sensitivity and specificity, with the ability to detect small amounts of DNA and provide results in just 45 minutes. It can serve as a rapid testing tool for mating type recognition of V. virens isolates in the field.

Summary: Understanding the number of mates an animal has in its lifetime is crucial for sexual selection. Differences in an organism's ecology can affect mating rates. Mating rate significantly impacts female fitness, but laboratory measurements might not accurately reflect the situation in the wild.

Summary: Sexual reproduction in fungi promotes genetic diversity and helps the fungus adapt to environmental stresses. This study compared 31 isolates of Fusarium verticillioides collected from eight provinces in China, and investigated their mating type, spore killing genotype, and pathogenicity. The findings provide valuable strain resources for investigating heterothallic sexual reproduction in F. verticillioides.

Summary: Comparative genetics and genomics among green plants, including algae, have provided deep insights into the evolution of land plant sexual reproduction. Recent studies have revealed the molecular mechanisms of sexual reproduction in land plants and integrated new genomics data to further understand the evolution of sexual reproduction. This new knowledge helps identify highly conserved factors and pathways, as well as molecular changes that support the emergence of new modes of sexual reproduction.

Summary: The study characterized the mating-type loci in Venturia carpophila, assessed its population genetic diversity and structure, and identified three genetic clusters among the isolates from various locations in the eastern United States. These findings provide a basis for further understanding the reproductive methods and genetics of the peach scab pathogen.

Summary: In this study, a velvet family regulator Cva1 was identified to specifically and critically elicit early mating events, including sexual cell-cell fusion, in the human fungal pathogen Cryptococcus deneoformans. This regulation provides insight into the regulatory specificity of mating in C. deneoformans.

Summary: The study revealed a new haploid mating system in Pleodorina starrii with three sex phenotypes: male, female, and bisexual. Genetic analyses suggested the presence of a autosomal bisexual factor locus independent of volvocine male and female determining regions, providing insight into the initial evolutionary step from heterothallism to homothallism. The findings indicated that the strains belong to the same biological species, with intercrossings demonstrating normal zygote formation and high survivability of F1 strains.
