Diversity, genetic structure and evidence of outcrossing in British populations of the rock fern Adiantum capillus-veneris using microsatellites [PDF]

, 2001
Microsatellites were isolated and a marker system was developed in the fern Adiantum capillus-veneris. Polymorphic markers were then used to study the genetic diversity and structure of populations within the UK and Ireland where this species grows at ...

Phenotypic characterization of Arabidopsis thaliana mutants that alleviate root growth defects in a vitamin B6 biosynthesis mutant

The FEBS Journal, EarlyView.
Vitamin B6 is a critical molecule for plant metabolism and development. Rsr4‐1, a loss‐of‐function mutant in a vitamin B6 biosynthesis gene, has a distinct short root phenotype. Here we describe five novel suppressor mutants with an rsr4‐1 background that have normalized root growth and distinct phenotypic and molecular characteristics, representing a ...

Floret sterility and outcrossing in two spring wheat cultivars

, 1999
A tendency for higher outcrossing potential in Canadian semidwarf wheat (Triticum aestivum L.) cultivars compared with tall Canadian cultivars has been postulated by breeders and seed growers.

Circadian rhythms of metabolite abundance in Drosophila are largely driven by time of feeding

The FEBS Journal, EarlyView.
Circadian clocks exist in the brain and peripheral tissues such as the Drosophila fat body. Single‐nuclei transcriptomics reveal that the fat body clock generates time‐of‐day differences in metabolic gene transcription, which may also be indirectly controlled by brain clocks.

THE ESTIMATION OF OUTCROSSING IN NATURAL POPULATIONS

The Japanese Journal of Genetics, 1958
A new method for estimating the proportion of outcrossing was developed by the use of maximum likelihood method. Using a qualitative character which is monogenically inherited, the proportion of outcrossing can be estimated in one or two generations. A numerical example was also given.

Natural outcrossing in groundnut and its implications in groundnut breeding [PDF]

, 1993
Estimates of outcrossing in four groundnut (Arachis hypogaea L.) varieties belonging to different botanical types were made from a rectangular crossing design where the normal plants were surrounded in all directions by a 'Krinkle' dominant leaf marker ...

Predicting Outcrossing in Maize Hybrid Seed Production

, 2009
Controlling pollination of the female inbred is critical to achieve maximum kernel set and high levels of genetic purity in maize (Zea mays L.) hybrid seed production.

Thermogenesis‐derived spatiotemporal microclimates guide pollinator movement to ensure pollination

Journal of Integrative Plant Biology, EarlyView.
Alocasia odora's microclimatic heterogeneity guides Colocasiomyia fly movement within its inflorescence. During the female stage, midday heat in the upper spadix pushes flies down to the cooler female zone. During the male stage, nocturnal warmth in the upper part pulls flies upward and spathe constriction closes the lower female chamber.

Data from: Genetic variation for outcrossing among Caenorhabditis elegans isolates

, 2017
The evolution of breeding systems results from the existence of genetic variation and selective forces favoring different outcrossing rates. In this study we determine the extent of genetic variation for characters directly related to outcrossing, such ...

Conservation implications of the mating system of the Pampa Hermosa landrace of peach palm analyzed with microsatellite markers

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
