Polyploidy is a prominent process in plant evolution; yet few data address the question of
whether homeologous sequences evolve independently subsequent to polyploidization. We …

Of the many processes that generate gene duplications, polyploidy is unique in that entire
genomes are duplicated. This process has been important in the evolution of many …

Abstract 5S RNA genes and their nontranscribed spacers are tandemly repeated in plant
genomes at one or more chromosomal loci. To facilitate an understanding of the forces that …

Recent work has demonstrated that allopolyploid speciation in plants may be associated
with non-Mendelian genomic changes in the early generations following polyploid …

Polyploid formation and processes that create partial genomic duplication generate
redundant genomic information, whose fate is of particular interest to evolutionary biologists …

Polyploid formation has played a major role in the evolution of many plant and animal
genomes; however, surprisingly little is known regarding the subsequent evolution of DNA …

Molecular evolutionary rate variation in Gossypium (cotton) was characterized using
sequence data for 48 nuclear genes from both genomes of allotetraploid cotton, models of …

We employ a detailed restriction fragment length polymorphism (RFLP) map to investigate
chromosome organization and evolution in cotton, a disomic polyploid. About 46.2% of …

Abstract.—Experimental advancedgeneration backcross populations contain individuals
with genomic compositions similar to those resulting from interspecific hybridization in …

The most widely cultivated species of cotton, Gossypium hirsutum, is a disomic tetraploid (2
n= 4 x= 52). It has been proposed previously that extant A-and D-genome species are most …
