Interpretive Summary: Cotton (Gossypium spp.) fibers are naturally soft, spinnable single-celled trichomes on the seed coat, which are economically and evolutionarily important to consider for scientific investigations Currently, there are more than 50 species of cotton. Two allotetraploid (G. hirsutum L. and G. barbadense L.) species are most widely cultivated commercially as sources of fiber (lint) for the textile industry and occupy the largest planting area throughout the world where cotton is grown. Cultivation of the two diploid (G. arboreum L. and G. herbaceum L.) species is confined only to a few Asian countries. Cotton is a source of dozens of products such as seed oil, seed meal, linters, and most important among these is the fiber, which is vital for textile manufactures. Since cotton has been domesticated for centuries, most of the cultivars have been developed for its valuable fibers but it is becoming increasingly difficult to improve the fiber quality using traditional breeding techniques. New approaches and technologies have been developed and used to improve fiber quality in many Gossypium species. A number of fiber trait-associated simple sequence repeat (SSR), expressed sequence tags-SSR (EST-SSR), and single nucleotide polymorphism (SNP) markers have been identified using cotton genome sequences and genetically tagged with DNA markers using experimental populations or germplasm resources. With the availability of genomic resources and advancements made in the past decade toward the characterization of cotton genomes, many novel genes, regulatory elements, including small and micro RNAs and their target genes, have been identified and novel genome manipulation tools developed. Current literature analysis indicates that RNAi (RNA Interference) and genome-edited (GE) technologies specific for improvement of fiber are being progressively investigated. In this chapter, emerging research approaches and efforts related to cotton fiber genomics are reviewed and discussed.
