Somatic genome‐doubling is the most parsimonious route to allopolyploidy

open access: yesNew Phytologist, EarlyView.
Summary The origin of a polyploid can hinge on a single errant cell division, a mistake in the cell cycle that leads to genome‐doubling and re‐writes the rules of chromosome pairing and segregation. In plants, the evolutionary significance of these errors is magnified by lack of an early sequestered germline, meaning somatic mutations can be heritable.

Diagnostic of Banana streak viruses (BSV) and study of their levels of prevalence and molecular diversity in Cuba [PDF]

open access: yes, 2011
Banana and plantain play a significant role in food security in Cuba, as reflected by the important surfaces (ca 101 000 ha) devoted to their culture. Interspecific triploid (AAB) and tetraploid (AAAB) plantain hybrids harbouring both the Musa acuminata (

Synthetic Raphanobrassica Genome Reveals Functional and Evolutionary Insights Into Clubroot Resistance Genes on Chromosome R5

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Clubroot, a severe soil‐borne disease caused by Plasmodiophora brassicae, poses a severe threat to global production of Brassicaceae oilseed crops and vegetables. To date, there has been a serious lack of clubroot‐resistant germplasms in Brassica napus (AACC), necessitating the urgent development of novel disease‐resistant germplasm.

Differential introgression and the maintenance of species boundaries in an advanced generation avian hybrid zone [PDF]

open access: yes, 2016
Background: Evolutionary processes, including selection and differential fitness, shape the introgression of genetic material across a hybrid zone, resulting in the exchange of some genes but not others.
