Plant genomes vary in size and complexity, fueled in part by processes of whole-genome
duplication (WGD; polyploidy) and subsequent genome evolution. Despite repeated …

Noncommercial varieties of potatoes (Solanum tuberosum L.) harbor genetic potential for
improvements of disease resistance and abiotic stress tolerance in commercial potato …

Polyploidization is an important speciation mechanism in the barley genus Hordeum. To
analyze evolutionary changes after allopolyploidization, knowledge of parental relationships …

Whole genome duplication (polyploidization) is a mechanism of “instantaneous” species
formation that has played a major role in the evolutionary history of plants. Much of what we …

Nicotiana, a member of the Solanaceae family, is one of the most important research model
plants, and of high agricultural and economic value worldwide. To better understand the …

Transcriptome sequencing or RNA-Seq is one of the most efficient and cost-effective
methods currently available for gene discovery in non-model organisms. Recent studies …

Allopolyploids, formed by hybridization and chromosome doubling, face the immediate
challenge of having duplicated nuclear genomes that interact with the haploid and …

Abstract Changes in chromosome structure and number play an important role in plant
evolution. This was investigated in the Neotropical epiphytic cacti: all Lepismium spp. and …

Background Forming a new species through the merger of two or more divergent parent
species is increasingly seen as a key phenomenon in the evolution of many biological …

Uncertainty in identifying Allocasuarina shrubs of the North Coast botanical region of New
South Wales and south-eastern Queensland prompted investigation of species limits using …
