... pattern of reticulate evolution was revealed with many diploid species and extensive polyploidy up to 20x. Altogether 11 groups of internal transcribed spacer (ITS) sequences can be distinguished. Sequences from 1-3 different ITS lineages were detected in polyploids. Cytogenetic data allow reconstruction...

... (Ultra-Lum). Asymmetrical meiosis Dogrose Interspecies hybrid Polyploidy rDNA Meiosis in polyploids has been investigated for a long time, revealing a number of ‘meiotic deviations' recently reviewed in Grandont et al. [2013]. Within the genus Rosa L., the section Caninae DC...

.... Polyploidy results from the union of 2 or more genomes in the same nucleus and is the major mode of plant genome evolution that can be artificially recreated. In Angiospermae, 30-70% of plant species have a polyploid origin, and almost all present species are considered to be paleopolyploids [Wendel, 2000...

...T.-L. Ashman; A. Kwok; B.C. Husband The evolutionary transition from hermaphroditism (combined sexes) to dioecy (separate sexes) is associated with whole genome duplication (polyploidy) in several flowering plant genera. Moreover, there is evidence for transitions in the opposite direction, i.e...

Since that time, considerable progress has been made in deciphering the cytological...

...M. Hegarty; J. Coate; S. Sherman-Broyles; R. Abbott; S. Hiscock; J.

However, research into the effects...
