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: High-quality de novo–assembled genomes of two cultivated allotetraploid cotton species and whole-genome comparative analyses provide insights into the evolution of cotton genomes and improvement of fiber quality and resilience to stress.

TL;DR: The genotype-by-sequencing method used to identify millions of SNPs between G. hirsutum and G. raimondii is reported, and the centromeric retro-element sequence of tetraploid cotton derived from the D subgenome progenitor might have invaded the A sub genome centromeres after allotetrapolyploid formation.

TL;DR: The present research reports the first observation of gene-mediated NATs and siRNA directly controlling fiber development in cotton and suggests that the bidirectional transcriptions of GhMML3_A12 form double-stranded RNAs and generate 21-22 nt small RNAs.

TL;DR: Characterization of target genes regulating fiber production has provided insights into the molecular mechanisms underlying cotton fiber development and has allowed the use of genetic engineering to increase lint yield by inducing more epidermal cells to develop into lint rather than fuzz fibers.
