Today we had the pleasure of hosting Prof. Jonathan Wendel from Iowa State University. Prof. Wendel explains the recent history of cotton domestication and the role that allopolyploidy (genome merging between related species) has played in this process. Cotton is an agronomically important plant that is intimately linked to many aspects of recent human history. Here we learn how diverse the Gossypium genus is in natural populations and how modern comparative genomics tools help us understand not only the history of genome duplication events but also the unexpected effects that allopolyploidy has on transcriptional programs in the hybrid offspring.
