Effects of mating-type ratio imbalance on the degeneration of Cordyceps militaris subculture and preventative measures [PDF]

PeerJ
The rapid degeneration of Cordyceps militaris strains during subculture represents a bottleneck problem that affects production stability. This study explored the mechanism underlying this degeneration in three production and three wild-type strains of ...

A seven-sex species recognizes self and non-self mating-type via a novel protein complex [PDF]

eLife
Although most species have two sexes, multisexual (or multi-mating type) species are also widespread. However, it is unclear how mating-type recognition is achieved at the molecular level in multisexual species.

Genetic Diversity, Population Structure and Mating Type Distribution of Setosphaeria turcica on Corn in Midwestern China [PDF]

Journal of Fungi, 2022
Setosphaeria turcica is the causal agent of northern corn leaf blight (NCLB), which is a destructive foliar disease of corn around the world. To date, limited information is available on the genetic diversity, population structure, and mating type ...

Stepwise recombination suppression around the mating-type locus in an ascomycete fungus with self-fertile spores. [PDF]

PLoS Genetics, 2023
Recombination is often suppressed at sex-determining loci in plants and animals, and at self-incompatibility or mating-type loci in plants and fungi. In fungal ascomycetes, recombination suppression around the mating-type locus is associated with pseudo ...

Identification and Characterization of the Gene Responsible for the O³ Mating Type Substance in Paramecium caudatum [PDF]

Microorganisms
The process of sexual reproduction in eukaryotes starts when gametes from two different sexes encounter each other. Paramecium, a unicellular eukaryote, undergoes conjugation and uses a gametic nucleus to enter the sexual reproductive process.

Characterization of the Aspergillus flavus Population from Highly Aflatoxin-Contaminated Corn in the United States

Toxins, 2022
Aflatoxin contamination of corn is a major threat to the safe food and feed. The United States Federal Grain Inspection Service (FGIS) monitors commercial grain shipments for the presence of aflatoxin. A total of 146 Aspergillus flavus were isolated from

Indirect Evidence Based on Mating-Type Ratios for the Role of Sexual Reproduction in European and Chinese Populations of Plenodomus biglobosus (Blackleg of Oilseed Rape)

Pathogens, 2022
Blackleg (Phoma) disease, caused by the ascomycete fungi Plenodomus biglobosus and P. lingam, threatens oilseed rape (OSR; Brassica napus) crops internationally. In many parts of the world, both species co-occur, but in China only P.

Mating Types in Screwworm Populations? [PDF]

Science, 1982
Response is given to questions raised by L.E. LaChance, et al., regarding the types of screwworm that occur in Mexico and anatomical differences in male genitalia among types. Errors in chromosome length and arm ratios are discussed. Results of testing the V-81 strain (sterile males) indicate that mating barriers exist even at high release rates ...

High Temporal Variability in Late Blight Pathogen Diversity, Virulence, and Fungicide Resistance in Potato Breeding Fields: Results from a Long-Term Monitoring Study

Plants, 2022
Long-term site-specific studies describing changes in the phenotypic variability of Phytophthora infestans populations allow quantitative predictions of pathogen spread and possible outbreaks of epidemics, and provide key input for regional resistance ...
