Introgressive Hybridization between Anciently Diverged Lineages of Silene (Caryophyllaceae)

open access: yesPLoS ONE, 2013
Hybridization has played a major role during the evolution of angiosperms, mediating both gene flow between already distinct species and the formation of new species. Newly formed hybrids between distantly related taxa are often sterile. For this reason, interspecific crosses resulting in fertile hybrids have rarely been described to take place after ...

Geographic Range Dynamics Drove Ancient Hybridization in a Lineage of Angiosperms [PDF]

open access: yesThe American Naturalist, 2017
AbstractFactors explaining global distribution patterns have been central to biology since the 19th century, yet failure to combine dispersal-based biogeography with shifts in habitat suitability remains a present-day setback in understanding geographic distributions present and past, and time-extended trajectories of lineages. The lack of methods in a

Hybridization and the origin of new yeast lineages

open access: yesFEMS Yeast Research, 2020
ABSTRACTHybrids originate from the mating of two diverged organisms, resulting in novel lineages that have chimeric genomes. Hybrids may exhibit unique phenotypic traits that are not necessarily intermediate between those present in the progenitors. These unique traits may enable them to thrive in new environments.

A six nuclear gene phylogeny of Citrus (Rutaceae) taking into account hybridization and lineage sorting. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND: Genus Citrus (Rutaceae) comprises many important cultivated species that generally hybridize easily. Phylogenetic study of a group showing extensive hybridization is challenging.

Recent, independent and anthropogenic origins of Trypanosoma cruzi hybrids. [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2011
The single celled eukaryote Trypanosoma cruzi, a parasite transmitted by numerous species of triatomine bug in the Americas, causes Chagas disease in humans. T.

Phylogenetic and Chemical Diversity of a Hybrid-Isoprenoid-Producing Streptomycete Lineage [PDF]

open access: yesApplied and Environmental Microbiology, 2013
ABSTRACT Streptomyces species dedicate a large portion of their genomes to secondary metabolite biosynthesis. A diverse and largely marine-derived lineage within this genus has been designated MAR4 and identified as a prolific source of hybrid isoprenoid (HI) secondary metabolites. These terpenoid-containing compounds

Genetic basis for spontaneous hybrid genome doubling during allopolyploid speciation of common wheat shown by natural variation analyses of the paternal species.

open access: yesPLoS ONE, 2013
The complex process of allopolyploid speciation includes various mechanisms ranging from species crosses and hybrid genome doubling to genome alterations and the establishment of new allopolyploids as persisting natural entities.

No evidence of a hybrid origin of the ashy‐throated parrotbill Sinosuthora alphonsiana

open access: yesJournal of Avian Biology, 2023
This mini‐review is dedicated to a critical re‐appraisal of the putative hybrid origin of the grey‐cheeked populations of the ashy‐throated parrotbill Sinosuthora alphonsiana that was postulated based on the results of a clustering analysis using a set ...
