Natural hybridization between divergent lineages in a selfing hermaphroditic fish [PDF]

Biology Letters, 2018
By definition, mating between individuals is infrequent in highly selfing organisms, and so too, therefore, hybridization should be rare between genetically divergent lineages in predominantly self-fertilizing species. Notwithstanding these expectations, here we report a remarkable case of natural hybridization between highly diverged phylogeographic ...

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

PLoS 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.

Automated Deep Lineage Tree Analysis Using a Bayesian Single Cell Tracking Approach

Frontiers in Computer Science, 2021
Single-cell methods are beginning to reveal the intrinsic heterogeneity in cell populations, arising from the interplay of deterministic and stochastic processes.

HYBRID SPECIATION AND INDEPENDENT EVOLUTION IN LINEAGES OF ALPINE BUTTERFLIES [PDF]

Evolution, 2013
The power of hybridization between species to generate variation and fuel adaptation is poorly understood despite long-standing interest. There is, however, increasing evidence that hybridization often generates biodiversity, including via hybrid speciation.

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

PLoS 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]

Applied 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

Assessment of Prunus Rootstock Accessions Using Chloroplast and Nuclear Microsatellites

Journal of the American Society for Horticultural Science, 2022
A rootstock collection of Prunus species and hybrids is maintained at the U.S. Department of Agriculture stone fruit breeding program at Byron, GA. We genotyped 66 Prunus rootstock accessions and clones using chloroplast and nuclear microsatellites in ...

Hybridization and gene flow in the mega-pest lineage of moth, Helicoverpa [PDF]

Proceedings of the National Academy of Sciences, 2018
Significance Helicoverpa armigera is a major agricultural and horticultural pest that recently spread from its historical distribution throughout much of the Old World to the Americas, where it is already causing hundreds of millions of dollars in damage every year.

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

PLoS 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.

Evidence of Natural Hybridization in Brazilian Wild Lineages ofSaccharomyces cerevisiae [PDF]

Genome Biology and Evolution, 2016
The natural biology of Saccharomyces cerevisiae, the best known unicellular model eukaryote, remains poorly documented and understood although recent progress has started to change this situation. Studies carried out recently in the Northern Hemisphere revealed the existence of wild populations associated with oak trees in North America, Asia, and in ...
