A genetic approach to the species problem in wild potato
(Wiley, 2012-07)Wild potatoes are native to the Americas, where they present very wide geographical and ecological distribution. Most are diploid, obligate out‐crossers due to a multiallelic gametophytic self‐incompatibility (S) locus ... -
Introgression from local cultivars is a driver of agricultural adaptation in Argentinian weedy rice
(Wiley, 2024-04-27)Weedy rice, a pervasive and troublesome weed found across the globe, has often evolved through fertilization of rice cultivars with little importance of crop-weed gene flow. In Argentina, weedy rice has been reported as ... -
Phylogenetic relationships and intraspecific diversity of a North Patagonian Fescue: evidence of differentiation and interspecific introgression at peripheral populations
(2018-03)Peripheral sites usually offer suboptimal conditions for species with wide distributions, where expression of phenotypic variability and potential interspecific hybridization might be enhanced. The Patagonian steppe, the ... -
Phylogeography of two hybridizing southern beeches (Nothofagus spp.) with different adaptive abilities
(Springer, 2011-12-17)In phylogenetically related plant species, hybridization can influence their current genetic structure. Long-lasting hybridization may be related to persistence in shared glacial refugia, where the differential abilities ...
