“…Immature fibers have relatively thin secondary cell walls that contain less cellulose than the cell walls of more mature fiber (Bradow et al, 1997). At mature stage (50 DPA), fiber in the normal sowed cotton had 7.8% greater cellulose content than that in late sowed cotton (Figure 2).…”

To study the effects of sowing date and boll position on fiber quality and the physiological mechanism, field experiments were conducted using two cotton cultivars (Kemian 1 and Sumian 15) with two sowing dates (normal sowing date 25 April, and late sowing date 25 May) at Nanjing (118°50′E, 32°02′N), Jiangsu, China, in 2006 and 2007. Cotton bolls were divided into three parts (low, middle and upper) according to the fruiting branch symbodial positions. Boll weight, fiber quality (bundle strength, span lengths, micronaire), and fiber physiological parameters (cellulose content, callose content, and sucrose transformation rate) were detected, respectively. Boll weight and fiber strength were affected by sowing date, boll position, and sowing date × boll position. Comparing to the normal sowing date, late sowing date declined boll weight, fiber strength, cellulose content, and sucrose transformation rate. The cellulose content and sucrose transformation rate changed with boll position, and consequently resulted in the change of boll weight and fiber strength. In normal sowing date, cotton boll in middle positional sympodial branch had the highest cellulose content, sucrose transformation rate, boll weight, and fiber strength. In late sowing date, cotton boll in low positional sympodial branch had the highest cellulose content, boll weight and fiber quality. The results indicated that the change of fiber yield and quality in sowing dates and boll positions were because the synthesis of cellulose, callose and sucrose were changed. Increasing the cellulose content and sucrose transformation rate can improve yield and fiber quality in late sowing date or sub-optimal environmental conditions.

“…Besides crop management, the physical environment had profound influence on cotton boll growth and development, which induced by fruiting sites (Davidonis et al, 2004). Bradow et al (1997) indicated that fiber length varied among fruiting sites. Wang et al (2009) indicated that fiber strength varied among the boll inserted location.…”

“…In the N1 condition, either the expression of the gene or the dynamics of the enzyme activity for SuSy and beta-1,3-glucanese were more optimized than that in N0 or N2, making the mass cellulose synthesis in N1 more stable and longer lasting ( Table 2 and Figure 5), matched with the request for high strength fiber development [1,2] . In the N1 condition, fiber strength increased most rapidly and finally the fiber strength was the highest.…”

“…Beta-1,3-glucanase activity in cotton fiber declined from 9 DPA till boll opening, and the beta-1, 3-glucanase coding gene expression also followed a unimodal curve in 12-24 DPA. In 240 kgN/hm 2 condition, the characteristics of enzyme activity and gene expression manner for sucrose synthase and beta-1,3-glucanase in developing cotton fiber were more favorable for forming a longer and more steady cellulose accumulation process, and for high strength fiber development.cotton (Gossypium hirsutum L.), nitrogen, fiber development, enzyme activity, gene expression, fiber strength Cotton (Gossypium hirsutum L.) fiber quality is determined by its genetic background and the growth environment [1,2] . The genetic backgrounds of most cultivars have been optimized.…”

To investigate the response of key enzymes to nitrogen (N) rates in cotton fiber and its relationship with fiber strength, experiments were conducted in 2005 and 2006 with cotton cultivars in Nanjing. Three N rates 0, 240 and 480 kgN/hm(2), signifying optimum and excessive nitrogen application levels were applied. The activities and the gene expressions of the key enzymes were affected by N, and the characteristics of cellulose accumulation and fiber strength changed as the N rate varied. Beta-1,3-glucanase activity in cotton fiber declined from 9 DPA till boll opening, and the beta-1, 3-glucanase coding gene expression also followed a unimodal curve in 12-24 DPA. In 240 kgN/hm(2) condition, the characteristics of enzyme activity and gene expression manner for sucrose synthase and beta-1,3-glucanase in developing cotton fiber were more favorable for forming a longer and more steady cellulose accumulation process, and for high strength fiber development.

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.
