“…Long lint fibers (>10 mm) can be easily separated from seeds through the ginning process. Recent studies indicated that both lint and fuzz fibers may share common developmental pathways at least in early differentiation, despite being under different genetic controls (Turley and Kloth, 2002;Wan et al, 2014Wan et al, , 2016Wu et al, 2018;Zhu et al, 2018). Fuzz fibers initiate ?3 to 5 DPA (Stewart, 1975;Wan et al, 2016) and stop elongating ?10 DPA.…”

“…Fuzz fibers are usually <5 mm in length and remain attached to the seeds after ginning (Zhang et al, 2007;Mauney, 2015). Currently, numerous naturally occurring cotton fiber mutants have been identified globally and characterized at the genetic, gene expression, and, more recently, genetic mapping (map-based cloning) levels (Rong et al, 2005;Hinchliffe et al, 2011;Kim et al, 2013a;Wang et al, 2014a;Naoumkina et al, 2015;Hu et al, 2016;Wan et al, 2016;Thyssen et al, 2017;Zhu et al, 2018). It is worth noting that it is difficult and often unpractical to differentiate fuzz fibers from extremely short (<6 mm) lint fibers before or after ginning.…”

“…An upland cotton mutant with the dominant N 1 locus was first reported in 1927 (Kearney and Harrison, 1927). A recent study indicated that the fuzzless phenotype in G. barbadense is mainly due to the presence of the n 2 gene (Zhu et al, 2018). A recessive n 2 locus was discovered in 1947 (Ware et al, 1947).…”

“…Rather than N 1 or n 2 , Turley and Kloth (2002) proposed a third locus n 3 controlling fuzzless trait when studying the genetic control of the fuzzless trait in cotton lines 143 and 243. However, a recent publication (Zhu et al, 2018) challenged this view. Musaev and Abzalov (1972) to be controlled by two loci, n 2 and li 3 , that regulate fuzz and lint fiber initiation, respectively (Zhang and Pan, 1991;Wu et al, 2018).…”

“…Virus-induced gene silence of GhMML3_A12 in cotton resulted in a fuzzless or reduced fuzz phenotype, but not a fiberless phenotype as seen in the transgenic cottons reported by Walford et al (2011). Recently, Zhu et al (2018) used G. barbadense ´ G. hirsutum interspecific populations to determine the tentative identity of the n 2 gene. The extremely low expression of GhMML3_A12 in N 1 is associated with NAT production driven by its 3¢ antisense promoter (Wan et al, 2016).…”

Cotton (Gossypium spp.) fibers are unicellular trichomes that differentiate from ovule epidermal cells. Cotton fiber development is divided into four distinct yet overlapping stages: initiation, elongation, secondary cell wall (SCW) biosynthesis, and maturation. There are numerous naturally occurring and man‐made fiber mutants that display aberrant phenotypes ranging from fiberless to extremely short fiber, and to immature fiber. These mutants have provided cotton researchers an excellent model system to study fiber growth and development. During the past two decades, much advancement in the understanding of fiber development has been achieved through comparative analyses of fiber mutants and wild‐type cotton lines using a variety of technologies such as transcriptomic analysis and genetic mapping. The causative genes of five mutations related to fiber initiation, elongation, or SCW assembly have been identified. Lint and fuzz fiber initiations are regulated by MYBMIXTA‐like transcription factors along with many other genes. Cytoskeleton actins play a critical role in fiber elongation. Genes that are involved in biological processes such as transporting osmoticum or loosening cell walls are highly expressed during the elongation stage. Production of large amounts of cellulose at the SCW stage requires a sustainable supply of energy and carbohydrate precursors. Plant hormones affect fiber development. In this paper, we review progress in the elucidation of fiber development mechanisms based on analyzing fiber mutants and summarize genes and mechanisms that are critical to fiber development. We identify research gaps that should be future research priorities and provide a future perspective.

Upland cotton (Gossypium hirsutum L.) is the main source of natural fiber for the textile industry. Cotton fibers are unicellular trichomes that emerge from the epidermal cells of the seed. In cultivated cotton species, seed trichomes differentiate into two distinct types, spinnable lint, and short fuzz. The main priority for cotton growers is fiber yield, whereas the textile industry also demands better fiber quality characteristics, such as length, uniformity, strength, maturity, and optimal fineness. However, it is a major challenge for breeders to improve fiber quality while maintaining yield, because of the observed negative correlation between yield and fiber quality traits. Recent technical advances in sequencing and bioinformatics have facilitated the assembly of reference quality genomes of multiple cotton species, bringing a new era for cotton genomics. Available genomic resources will help genetically dissect the agronomic and fiber quality traits of cotton and identify gene variants that can be used for cotton improvement through breeding or biotechnology. Here, we review recent progress in the sequencing of genomes of cotton species and approaches in molecular genetics and genomics for the improvement of cotton fiber quality traits.We discuss progress in the understanding of each stage of cotton fiber development and the remaining challenges.
