Mating system and role of pycnidiospores in biology of Polystigma amygdalinum, the causal agent of almond red leaf blotch

open access: yesPhytopathologia Mediterranea, 2016
Polystigma amygdalinum is a serious leaf pathogen of almonds. Ascospores are believed to be the only inoculum of this pathogen. Ascocarp initials develop in infected leaves in contact with, or in close proximity to, filimentous spore-bearing bodies ...

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

Plant Mating Systems Often Vary Widely Among Populations

open access: yesFrontiers in Ecology and Evolution, 2018
Most flowering plants are hermaphroditic, yet the proportion of seeds fertilized by self and outcross pollen varies widely among species, ranging from predominant self-fertilization to exclusive outcrossing.

Mixed mating system and variable mating patterns in tropical woody bamboos

open access: yesBMC Plant Biology, 2019
Background So far, little is known in detail about mating systems of woody bamboos. Paternity analysis of offspring improved our understanding of these systems, and contributed to their germplasm conservation and genetic improvement.

Mating system drives negative associations between morphological features in Schistosomatidae

open access: yesBMC Evolutionary Biology, 2010
Background Sexual morphological features are known to be associated with the mating systems of several animal groups. However, it has been suggested that morphological features other than sexual characteristics could also be constrained by the mating ...

A Comment on "Mate Recognition Systems" [PDF]

open access: yesEvolution, 1980
In a recent response to a note by Ringo (1977) on "Why 300 species of Hawaiian Drosophila?," Templeton (1979) introduced a new aspect to the discussion. This was the idea of the Mate Recognition System, or, as I now prefer to call it, the Specific-Mate Recognition System (SMRS), which I introduced in 1976.

On extending the Hardy-Weinberg law

open access: yesGenetics and Molecular Biology, 2007
This paper gives a general mating system for an autosomal locus with two alleles. The population reproduces in discrete and non-overlapping generations.

Mating system variation drives rapid evolution of the female transcriptome in Drosophila pseudoobscura [PDF]

open access: yes, 2014
This research was part funded by the Natural Environment Research Council, Grant Number: NE/I014632/1. The APC was paid through RCUK open access block grant funds.Interactions between the sexes are believed to be a potent source of selection on sex ...

Animal‐borne video systems provide insight into the reproductive behavior of the Asian black bear

open access: yesEcology and Evolution, 2021
Previous studies on the mating system of the Asian black bear (Ursus thibetanus) have been limited to observations of captive populations and estimations of multiple paternities. Hence, the mating system of wild bears remains poorly understood.

Genetic Basis of Self-Incompatibility in the Lichen-Forming Fungus Lobaria pulmonaria and Skewed Frequency Distribution of Mating-Type Idiomorphs: Implications for Conservation [PDF]

open access: yes, 2012
Fungal populations that reproduce sexually are likely to be genetically more diverse and have a higher adaptive potential than asexually reproducing populations.
