Sequencing of allotetraploid cotton (Gossypium hirsutum L. acc. TM-1) provides a resource for fiber improvement
TLDR
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. Expand
Repeated polyploidization of Gossypium genomes and the evolution of spinnable cotton fibres
TLDR
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. Expand
A detailed RFLP map of cotton, Gossypium hirsutum x Gossypium barbadense: chromosome organization and evolution in a disomic polyploid genome.
TLDR
The cotton map affords new opportunities to study chromosome evolution, and to exploit Gossypium genetic resources for improvement of the world's leading natural fiber, hence map-based gene cloning is feasible. Expand
Resistance gene candidates identified by PCR with degenerate oligonucleotide primers map to clusters of resistance genes in lettuce.
TLDR
The use of PCR with degenerate oligonucleotide primers is an efficient method to identify numerous RGCs in plants and demonstrates the existence of clustered multigene families for each of the four RGC sequences. Expand
Dispersed repetitive DNA has spread to new genomes since polyploid formation in cotton.
TLDR
The discovery of A-genome repeats in G. gossypioides adds genome-wide support to a suggestion previously based on evidence from only a single genetic locus that this species may be either the closest living descendant of the New World cotton ancestor, or an adulterated relic of polyploid formation. Expand
Accumulation of genome-specific transcripts, transcription factors and phytohormonal regulators during early stages of fiber cell development in allotetraploid cotton.
TLDR
The results suggest general roles for genome-specific, phytohormonal and transcriptional gene regulation during the early stages of fiber cell development in cotton allopolyploids. Expand
Chromosomal assignment of microsatellite loci in cotton.
TLDR
A protocol for high-throughput genotyping of cotton SSRs is provided that improves the efficiency of genetic mapping and marker-assisted programs utilizing SSR markers. Expand
Genetic mapping and QTL analysis of fiber-related traits in cotton (Gossypium)
TLDR
A genetic map in an F2 population derived from interspecific hybrids between G. hirsutum L. cv. Expand
Development of a 63K SNP Array for Cotton and High-Density Mapping of Intraspecific and Interspecific Populations of Gossypium spp.
TLDR
The produced intraspecific genetic map is the first saturated map that associates into 26 linkage groups corresponding to the number of cotton chromosomes for a cross between two G. hirsutum lines. Expand
Genetic mapping of new cotton fiber loci using EST-derived microsatellites in an interspecific recombinant inbred line cotton population
TLDR
These new PCR-based microsatellite markers derived from cotton fiber ESTs will facilitate the development of a high-resolution integrated genetic map of cotton for structural and functional study of fiber genes and MAS of genes that enhance fiber quality. Expand
