REGULATION OF MATING AND MEIOSIS IN YEAST BY THE MATING-TYPE REGION [PDF]

open access: yesGenetics, 1976
ABSTRACT A supposed sporulation-deficient mutation of Saccharomyces cerevisiae is found to affect mating in haploids and in diploids, and to be inseparable from the mating-type locus by recombination. The mutation is regarded as a defective a allele and is designated a*. This is confirmed by its dominance relations in diploids, triploids,

Evolutionary dynamics of mating-type loci of Mycosphaerella spp. occurring on banana [PDF]

open access: yes, 2010
The devastating Sigatoka disease complex of banana is primarily caused by three closely related heterothallic fungi belonging to the genus Mycosphaerella: M. fijiensis, M. musicola, and M. eumusae.

Regulation of mating type switching by the mating type genes and RME1 in Ogataea polymorpha [PDF]

open access: yesScientific Reports, 2017
Abstract Saccharomyces cerevisiae and its closely related yeasts undergo mating type switching by replacing DNA sequences at the active mating type locus ( MAT ) with one of two silent mating type cassettes. Recently, a novel mode of mating type switching

Assortative roosting in the two phonic types of Pipistrellus pipistrellus during the mating season [PDF]

open access: yes, 1996
The European pipistrelle, Pipistrellus pipistrellus, consists of two phonic types that echolocate with frequencies of maximum energy (FMAXE) averaging 46 kHz and 55 kHz (named the 45 kHz and 55 kHz phonic types for simplicity).

The repeatability of mating failure in a polyandrous bug [PDF]

open access: yes, 2015
Funding: NERC DTG ABE1-NERC13Mating failure, characterised by the lack of production of offspring following copulation, is relatively common across taxa yet is little understood.

Genetic diversity and population structure of Ascochyta rabiei from the western Iranian Ilam and Kermanshah provinces using MAT and SSR markers [PDF]

open access: yes, 2010
Knowledge of genetic diversity in A. rabiei provides different levels of information that are important in the management of crop germplasm resources. Gene flow on a regional level indicates a significant potential risk for the regional spread of novel ...

No Detectable Fertility Benefit from a Single Additional Mating in Wild Stalk-Eyed Flies [PDF]

open access: yes, 2010
Background: Multiple mating by female insects is widespread, and the explanation(s) for repeated mating by females has been the subject of much discussion.

Stimulation Study of Gene Pyramiding in Animals by Marker-Assisted Selection

open access: yesJournal of Integrative Agriculture, 2012
This gene pyramiding strategy is based on the idea of efficiently pyramiding genes of interest by crosses and selection to obtain a population with favorable alleles from different breeds or lines, which is called an ideal population.

Evolution of Divergent Female Mating Preference in Response to Experimental Sexual Selection [PDF]

open access: yes, 2014
Sexual selection is predicted to drive the coevolution of mating signals and preferences (mating traits) within populations, and could play a role in speciation if sexual isolation arises due to mating trait divergence between populations. However, few
