Mitochondrial differentiation, introgression and phylogeny of species in the Tegenaria atrica group (Araneae, Agelenidae) [PDF]

open access: yes, 2004
The relationships between the three members of the Tegenaria atrica group (T. atrica, T. saeva and T. gigantea) were examined with DNA sequence data from mitochondrial CO1, 16S rRNA, tRNAleu(CUN) and ND1 genes.

Phylogeny and new sectional classification for the Cape Clade of the genus Indigofera (Fabaceae: Indigofereae)

open access: yesTAXON, EarlyView.
Abstract The genus Indigofera in the Greater Cape Floristic Region (GCFR) comprises a diverse assortment of species. Almost 90% of the region's Indigofera species belong to the Cape Clade, while the remaining species are scattered among the other three globally distributed Indigofera clades.

Advanced Backcross QTL Analysis of Fiber Strength and Fineness in a Cross between Gossypium hirsutum and G. mustelinum

open access: yesFrontiers in Plant Science, 2017
The molecular genetic basis of cotton fiber strength and fineness in crosses between Gossypium mustelinum and Gossypium hirsutum (Upland cotton) was dissected using 21 BC3F2 and 12 corresponding BC3F2:3 and BC3F2:4 families.

Three previously characterized resistances to yellow rust are encoded by a single locus Wtk1. [PDF]

open access: yes, 2020
The wild emmer wheat (Triticum turgidum ssp. dicoccoides; WEW) yellow (stripe) rust resistance genes Yr15, YrG303, and YrH52 were discovered in natural populations from different geographic locations.

Eucalyptus was not the problem: A response to “The genus problem – Eucalyptus as a model system for minimising taxonomic disruption” by Nicolle & al.

open access: yesTAXON, EarlyView.
Abstract In a recent perspective paper in Taxon, Nicolle and coauthors advocate a broad circumscription of the Australian genus Eucalyptus (Myrtaceae), based on six “rules” for delimiting plant genera. The current consensus, established through the Australian Plant Census (APC), is a three‐genus classification system (Angophora, Corymbia, Eucalyptus ...

An introgressed wing pattern acts as a mating cue. [PDF]

open access: yes, 2015
Heliconius butterflies provide good examples of both homoploid hybrid speciation and ecological speciation. In particular, examples of adaptive introgression have been detected among the subspecies of Heliconius timareta, which acquired red color pattern

Introgressive Hybridization and the Evolution of Lake-Adapted Catostomid Fishes. [PDF]

open access: yes, 2016
Hybridization has been identified as a significant factor in the evolution of plants as groups of interbreeding species retain their phenotypic integrity despite gene exchange among forms.

Biological Flora of Britain and Ireland: Cytisus scoparius*

open access: yesJournal of Ecology, EarlyView.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.

What are the consequences of water stress on the development of late postzygotic reproductive isolation in an orchid hybrid zone?

open access: yesPlant Species Biology, EarlyView.
Hybrids vulnerable to drought may increase postzygotic isolation in hybrid zones. Drought experiments can reveal the influence of climate change on hybrid zones. Crassulacean acid metabolism in parental species and hybrids was negatively affected by drought.

Genetic Regulatory Perturbation of Gene Expression Impacted by Genomic Introgression in Fiber Development of Allotetraploid Cotton

open access: yesAdvanced Science
Interspecific genomic introgression is an important evolutionary process with respect to the generation of novel phenotypic diversity and adaptation. A key question is how gene flow perturbs gene expression networks and regulatory interactions.
