Long-distance insular dispersal is associated with divergence and speciation because of
founder effects and strong genetic drift. The cotton tribe (Gossypieae) has experienced …

Domestication in the cotton genus is remarkable in that it has occurred independently four
different times at two different ploidy levels. Relatively little is known about genome evolution …

The origin and monophyly of the polyploid cotton (Gossypium) species has been largely
accepted, despite the lack of explicit phylogenetic evidence. Recent studies in other …

Polyploidy (ie, hybridization between more or less divergent genomes, associated with
whole genome duplication) has been shown to result in drastic genome reorganization …

Clusterbean (C. tetragonoloba) is an important, leguminous vegetable and industrial crop
with vast genetic diversity but meager genetic, cytological and genomic information. In the …

Retrotransposon-based molecular markers were applied for the first time within the genera
Xanthosoma and Colocasia to assess intraspecific variability among 27 accessions of …

The cytoplasmic male sterility (CMS) system is ideal for exploiting heterosis in crops such as
cotton. However, CMS-D2, which is based on Gossypium harknessii cytoplasm, is still not …

Evidence accumulated over the last decade has shown that allopolyploid genomes may
undergo drastic reorganization. However, timing and mechanisms of structural diploidization …

Populus tomentosa, of section Populus, is distributed mainly in northern China. This species
has high resistance to many diseases and insects, and it plays key roles in shelterbelts and …

Retrotransposons and their remnants often constitute more than 50% of higher plant
genomes. Although extensively studied in monocot crops such as maize (Zea mays) and …
