Gene expression during the early stages of fiber cell development and in allopolyploid crops
is poorly understood. Here we report computational and expression analyses of 32 789 high …

Background Cotton is the dominant source of natural textile fibre and a significant oil crop.
Cotton fibres, produced by certain species in the genus Gossypium, are seed trichomes …

Allopolyploidy is an evolutionary and mechanistically intriguing process, in that it entails the
reconciliation of two or more sets of diverged genomes and regulatory interactions. In this …

Allotetraploid cotton (Gossypium) species represents a model system for the study of plant
polyploidy, molecular evolution, and domestication. Here, chromosome-scale genome …

Background Modern allotetraploid cotton contains an “A” and “D” genome from an ancestral
polyploidy event that occurred approximately 1–2 million years ago. Diploid A-and D …

Little is still known about the developmental control of the long seed coat trichomes of cotton
(Gossypium hirsutum L.). In Arabidopsis, leaf trichome initiation is regulated by a group of …

MYB transcription factors have been implicated in regulation of the development of ovule
epidermal cells into the elongated seed fibres of cotton. An R2R3 MYB, GhMYB25‐like …

Cotton fibres are a subset of single epidermal cells that elongate from the seed coat to
produce the long cellulose strands or lint used for spinning into yarn. To identify genes that …

Polyploidy complicates transcriptional regulation and increases phenotypic diversity in
organisms. The dynamics of genetic regulation of gene expression between coresident …

Highlights•Seed trichome or fiber in cotton serves as an ideal model to study plant cell
