We used next generation sequencing to characterize and compare the genomes of the
recently derived allotetraploid, Nicotiana tabacum (< 200,000 years old), with its diploid …

Background Polyploidization is an important mechanism in plant evolution. By analyzing the
leaf transcriptomes taken from the allotetraploid Nicotiana tabacum (tobacco) and parental …

Nicotiana section Suaveolentes is an almost all‐Australian clade of allopolyploid tobacco
species including the important plant model Nicotiana benthamiana. The homology …

Nicotiana tabacum (tobacco, 2n= 4x= 48) is a natural allotetraploid combining two ancestral
genomes closely related to modern Nicotiana sylvestris and Nicotiana tomentosiformis. Here …

The nuclear cytoplasmic interaction (NCI) hypothesis of genome evolution and speciation in
plants states that newly formed allopolyploids pass through a bottleneck of sterility and the …

Allopolyploidy (interspecific hybridisation and polyploidy) has played a significant role in the
evolutionary history of angiosperms and can result in genomic, epigenetic and …

We review and extend data showing concerted evolution of parental 18–5.8–26S nuclear
ribosomal DNA (18–26S rDNA) gene families in three natural Nicotiana allotetraploids (N …

Abstract Background Nicotiana rustica (Aztec tobacco), like common tobacco (Nicotiana
tabacum), is an allotetraploid formed through a recent hybridization event; however, it …

Combining phylogenetic reconstructions of species relationships with comparative genomic
approaches is a powerful way to decipher evolutionary events associated with genome …

Nicotiana sect. Repandae is a group of four allotetraploid species originating from a single
allopolyploidisation event approximately 5 million years ago. Previous phylogenetic …
