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.

Effect of gradual pollen presentation on pollination efficiency and reproduction of Vaccinium corymbosum Berkeley in two habitats

Frontiers in Ecology and Evolution
IntroductionGradual pollen presentation is a reproductive strategy for plants to improve the efficiency and accuracy of pollen export and acceptance as well as to promote outcrossing.

Simulation and Assessment of Possible Environmental Risks Associated with Release of Genetically Modified Peas (Pisum sativum L.) into Environment in Central Europe

Czech Journal of Genetics and Plant Breeding, 2005
Environmental risks connected with the release of genetically modified peas into the environment were studied in simulated field experiments. They included (1) an assessment of pollen transfer and the rate of natural outcrossing between commercial peas ...

Glomage: A Multimodal Platform for High‐Content Morphological and RNA Profiling of Glomeruli in Zebrafish and Mouse Models

Advanced Science, EarlyView.
Understanding how glomeruli, the kidney's filtration units, function in intact tissue remains challenging. Glomage enables rapid 3D imaging and quantitative analysis of entire glomeruli from zebrafish larvae and mice. This approach allows scalable cell quantification and detection of structural changes, advancing kidney disease research and ...

Characterization of Deleterious Mutations in Outcrossing Populations [PDF]

Genetics, 1998
Abstract Deng and Lynch recently proposed estimating the rate and effects of deleterious genomic mutations from changes in the mean and genetic variance of fitness upon selfing/outcrossing in outcrossing/highly selfing populations. The utility of our original estimation approach is limited in outcrossing populations, since selfing may ...

Pericentrosomal Redistribution of the Endoplasmic Reticulum Ensures Organelle Symmetric Inheritance and Mitotic Progression

Advanced Science, EarlyView.
Upon mitotic entry, RTN4 relocalizes to the pericentrosomal region, forming a more tubular ER network around centrosomes. CDK1‐mediated phosphorylation of RTN4 increases its interaction with Rab11 GTPase, facilitating dynein‐dependent transport of RTN4 to the pericentrosomal region.

Ovaries with different heterozygosity levels of their genotypes have equal chances to reach maturity on a buckwheat plant: Is it the main condition for the start of the evolution toward selfing?

Труды по прикладной ботанике, генетике и селекции
Background. Inbreeding depression (ID) usually reduces the competitive ability of an individual compared to one of outbred origin. Such competition could be especially clear between different ovaries developing on the same plant.

Population genetics of fungal diseases of plants

Parasite, 2008
Although parasitism is one of the most common lifestyles among eukaryotes, population genetics on parasites lag far behind those on free-living organisms.
