TL;DR: Genomic signatures of selection and domestication are associated with positively selected genes (PSGs) for fiber improvement in the A subgenome and for stress tolerance in the D subgenomes, suggesting asymmetric evolution.

TL;DR: It is shown that an abrupt five- to sixfold ploidy increase approximately 60 million years (Myr) ago, and allopolyploidy reuniting divergent Gossypium genomes approximately 1–2 Myr ago, conferred about 30–36-fold duplication of ancestral angiosperm genes in elite cottons, genetic complexity equalled only by Brassica among sequenced angiosperms.
Journal ArticleDOI
Suppression of Sucrose Synthase Gene Expression Represses Cotton Fiber Cell Initiation, Elongation, and Seed Development
TL;DR: It is demonstrated that Sus plays a rate-limiting role in the initiation and elongation of the single-celled fibers and that suppression of Sus only in the maternal seed tissue represses fiber development without affecting embryo development and seed size.
Journal ArticleDOI
The Control of Single-Celled Cotton Fiber Elongation by Developmentally Reversible Gating of Plasmodesmata and Coordinated Expression of Sucrose and K+ Transporters and Expansin
TL;DR: This study provides an unprecedented demonstration that the gating of plasmodesmata in a given cell is developmentally reversible and is coordinated with the expression of solute transporters and the cell wall–loosening gene.
Journal ArticleDOI
Arabidopsis RAP2.2: An ethylene response transcription factor that is important for hypoxia survival
Manuela Hinz,Iain W. Wilson,Jun Yang,Katharina Buerstenbinder,Danny J. Llewellyn,Elizabeth S. Dennis,Margret Sauter,Rudy Dolferus +7 more
TL;DR: The results provide a new insight on the regulation of gene expression under low-oxygen conditions and show that lighting plays an important regulatory role and is intertwined with hypoxia conditions; both stimuli may act collaboratively to regulate the hypoxic response.
