Genetic self-compatibility in a south american species of ourisia (scrophulariaceae)
(1990)
Controlled hand self- and cross-pollination and emasculations were performed on Ourisia poeppigii Benth. (Scrophulariaceae) from the Chilean Patagonia. Ourisia poeppigii is highly self-compatible and strongly autogamous. ...
Transitions between self-compatibility and self-incompatibility and the evolution of reproductive isolation in the large and diverse tropical genus Dendrobium (Orchidaceae)
(Oxford Univ Press, 2015-09-01)
Methods The role of SC and SI changes in reproductive compatibility among species was examined using fruit set and seed viability data available in the literature from 86 species and 2500 hand pollinations. The evolution ...
Self-Compatibility Not Associated with Morphological or Genetic Diversity Reduction in Oil-Rewarding Calceolaria Species
(MDPI Multidisciplinary Digital Publishing Institute, 2020-10)
One of the most common evolutionary transitions in angiosperms is the reproductive change from outcrossing to selfing, commonly associated with changes in floral biology and genetic diversity. Here, we aim to test whether ...
Self-incompatibility, inbreeding depression and crossing potential in five Brazilian Pleurothallis (Orchidaceae) species
(Academic Press LtdLondonInglaterra, 2001)
Grafting as a management tool to control Meloidogyne incognita in okra: Identifying rootstocks candidates
(2019-02-27)
The root-knot nematodes (RKN) challenge okra production (Abelmoschus esculentus L. Moench) worldwide and there are no reports of genetic resistance within the genus Abelmoschus. As an alternative, the compatibility for ...
Assessment of Mating System in Helianthus annuus and H. petiolaris (Asteraceae) Populations
(Institute of Field and Vegetable Crops, 2019-11-23)
Helianthus annuus subsp. annuus and H. petiolaris are wild NorthAmerican species that have been naturalized in central Argentina. They have asporophytic self-incompatibility genetic system that prevent self-fertilization ...
Pollen flow within and among isolated populations of two rare, self-compatible plant species from inselbergs of Northeast Brazil
(Springer, 2020-04)
Endangered species in isolated habitats (e.g., inselbergs) may escape mate limitation during patch colonization through autonomous self-pollination. After colonization, the higher the number of plants breeding randomly ...
Genetic relatedness of Brazilian Colletotrichum truncatum isolates assessed by vegetative compatibility groups and RAPD analysis
(Sociedad de Biología de Chile, 2010)
Self-pollination and its implication in invasiveness of Helianthus annuus ssp. annuus and H. petiolarisAutopolinización y su implicancia en la invasividad de Helianthus annuus ssp. annuus y H. petiolaris
(Sociedad Argentina de Genética, 2014-12)
Helianthus petiolaris and H. annuus are exotic invaders that have spread widely in central Argentina in the last 70 years. As other annuals of the same genus, these species are outcrossers bearing a sporophytic self-incompatible ...
