A century of theories of balancing selection
Biological Reviews, EarlyView.ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

Genetics and Molecular Biology, 2015 Peach palm (Bactris gasipaes) is cultivated by many indigenous and traditional communities from Amazonia to Central America for its edible fruits, and is currently important for its heart-of-palm. The objective of this study was to investigate the mating

Optimization of the composition of crop collections for ex situ conservation [PDF]
, 2009 Many crop genetic resources collections have been established without a clearly defined conservation goal or mandate, which has resulted in collections of considerable size, unbalanced composition and high levels of duplication.

Natural outcrossing rate in Vernonia galamensis
Plant Breeding, 2004 Abstract Vernonia galamensis is a potential new industrial crop growing wild in Ethiopia. The seed oil is rich in vernolic acid, an epoxy fatty acid, which is of interest for oleochemical uses. Basic information on the reproductive system of Vernonia is still very limited.

OUTCROSSING IN NATURAL POPULATIONS. V. ANALYSIS OF OUTCROSSING, INBREEDING, AND SELECTION IN CLARKIA EXILIS AND CLARKIA TEMBLORIENSIS [PDF]
Evolution, 1976 Earlier papers in this series (Vasek, 1964b, 1965, 1967, 1968) have been concerned with the estimation of outcrossing for the purpose of comparing the breeding systems of closely related Clarkia species. Outcrossing estimates have been obtained for three populations of Clarkia exilis and one population of Clarkia unguiculata.

Mobile DNA, 2012 BackgroundTransposable elements (TEs) are major contributors to genome evolution. One factor that influences their evolutionary dynamics is whether their host reproduces through selfing or through outcrossing.

The FEBS Journal, EarlyView.midkine‐a (mdka), a pan‐injury response gene in vertebrates, is precisely regulated in the zebrafish telencephalon by a modular cis‐regulatory architecture. This control ensures proper expression during development, adult brain homeostasis, and regeneration.

Plants, 2019 Life histories and breeding systems strongly affect the genetic diversity of seed plants, but the genetic architectures that promote outcrossing in Oryza longistaminata, a perennial wild species in Africa, are not understood.

Gene flow of oilseed rape (Brassica napus)according to isolation distance and buffer zone [PDF]
, 2005 The introduction of genetically modified (GM) crops in the EU has raised questions concerning gene dispersal and co-existence with non-GM farming. Quantitative estimates of the gene dispersal from fields with GM crops to fields with conspecific non-GM ...

Journal of Applied Entomology, EarlyView.ABSTRACT Pollination is a key ecosystem service, yet most studies focus on diurnal interactions, often overlooking nocturnal pollinators such as hawkmoths and settling moths. In arid environments, nocturnal pollination plays a crucial role in maintaining native plant species of high biocultural value, as seen in the Caatinga dry forest.
