“…During the elongation period, fiber cells elongate rapidly from three to five days post-anthesis (DPA), peak at around 10 DPA, and eventually grow up to 30 to 40 mm in length (Basra and Sukumar, 2000). Cotton fibers are among the longest cells characterized in the plant kingdom, and are not interrupted by cell division for a relatively long period; therefore, these fibers are used in the study of cell elongation and cell wall deposition (Cao, 2015;Deng et al, 2012;Lee et al, 2007;Li et al, 2015;Luo et al, 2007;Pei, 2015;Shan et al, 2014;Shi et al, 2006;Xiao et al, 2010;Yang et al, 2006;Yang et al, 2014;Zhang et al, 2011;Zhang et al, 2015).…”

Phytosterols play an important role in plant growth and development, including cell division, cell elongation, embryogenesis, cellulose biosynthesis, and cell wall formation. Cotton fiber, which undergoes synchronous cell elongation and a large amount of cellulose synthesis, is an ideal model for the study of plant cell elongation and cell wall biogenesis. The role of phytosterols in fiber growth was investigated by treating the fibers with tridemorph, a sterol biosynthetic inhibitor. The inhibition of phytosterol biosynthesis resulted in an apparent suppression of fiber elongation in vitro or in planta. The determination of phytosterol quantity indicated that sitosterol and campesterol were the major phytosterols in cotton fibers; moreover, higher concentrations of these phytosterols were observed during the period of rapid elongation of fibers. Furthermore, the decrease and increase in campesterol : sitosterol ratio was associated with the increase and decease in speed of elongation, respectively, during the elongation stage. The increase in the ratio was associated with the transition from cell elongation to secondary cell wall synthesis. In addition, a number of phytosterol biosynthetic genes were down-regulated in the short fibers of ligon lintless-1 mutant, compared to its near-isogenic wild-type TM-1. These results demonstrated that phytosterols play a crucial role in cotton fiber development, and particularly in fiber elongation. cotton fiber, phytosterols, gene expression, tridemorph, ligon lintless-1 Citation:Deng, S., Wei, T., Tan, K., Hu, M., Li, F., Zhai, Y., Ye, S., Xiao, Y., Hou, L., Pei, Y., and Luo, M.

“…It is a major resource of natural fiber in the textile industry, and also can provide a significant amount of oilseed for food and biofuel (Cao, 2015;Pei, 2015). In the previous proteomic studies, PLDs were proposed to be involved in cotton fiber development.…”

“…In the past years, great achievements have been made in sequencing the diploid (G. raimondii and G. arboreum) (Paterson et al, 2012;Wang et al, 2012) and tetraploid G. hirsutum and G. barbadense genomes (Cao, 2015;Zhang et al, 2015). These will greatly facilitate resolving the biosynthesis pathway and regulation mechanism of cadinene-type phytoalexins.…”

Sesquiterpenoids are a class of 15-carbon secondary metabolites that play diverse roles in plant adaptation to environment. Cotton plants accumulate a large amount of sesquiterpene aldehydes (including gossypol) as phytoalexins against pathogens and herbivores. They are stored in pigment glands of aerial organs and in epidermal layers of roots. Several enzymes of gossypol biosynthesis pathway have been characterized, including 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR) and farnesyl diphosphate synthase (FPS) that catalyze the formation of the precursor farnesyl diphosphate (FPP), (+)--cadinene synthase (CDN) which is the first enzyme committed to gossypol biosynthesis, and the downstream enzymes of CYP706B1 and methyltransferase. Expressions of these genes are tightly regulated during cotton plants development and induced by jasmonate and fungi elicitors. The transcription factor GaWRKY1 has been shown to be involved in gossypol pathway regulation. Recent development of new genomic platforms and methods and releases of diploid and tetraploid cotton genome sequences will greatly facilitate the elucidation of gossypol biosynthetic pathway and its regulation.cotton, secondary metabolism, gossypol, sesquiterpenoid Citation:
