“…Several studies have been focused on the analysis of the composition of the cell wall extracts (Tokumoto et al 2002;Timpa and Triplett 1993;Meinert and Delmer 1977;Maltby et al 1979;Huwyler et al 1979;Gokani et al 1998). However, limited research has been conducted on intact fibers.…”

Cotton fiber maturity is a major yield component and an important fiber quality trait that is directly linked to the quantity of cellulose deposited during the secondary cell wall (SCW) biogenesis. Cotton fiber development consists of five major overlapping stages: differentiation, initiation, polar elongation, secondary cell wall development, and maturation. The transition period between 16 and 21 dpa (days post anthesis) is regarded to represent a major developmental stage between the primary cell wall and the SCW. Fourier Transform Infrared spectroscopy was used to investigate the structural changes that occur during the different developmental stages. The IR spectra of fibers harvested at different stages of development (10, 14, 17, 18, 19, 20, 21, 24, 27, 30, 36, 46, and 56 dpa) show the presence of vibrations located at 1,733 cm -1 (C=O stretching originating from esters or amides) and 1,534 cm -1 (NH 2 deformation corresponding to proteins or amino acids). The results converge towards the conclusion that the transition phase between the primary cell wall and the secondary cell wall occurs between 17 and 18 dpa in fibers from TX19 cultivar, while this transition occurs between 21 and 24 dpa in fibers from TX55 cultivar.

Universal attenuated total reflectance Fourier transform infrared (UATR‐FTIR) spectroscopy and thermogravimetric analysis (TGA) were used to investigate the structural changes of cotton (Gossypium hirsutum L.) fibers as a function of developmental programming. The presence of noncellulosic compounds (wax, protein, hemicelluloses, pectic substances, amino acids, etc.) was evident from FTIR spectra of fibers at 10, 14, 17, and 20 dpa (day postanthesis). The vibration corresponding to the noncellulosic compounds disappeared at 36 dpa. Furthermore, independent TGA analysis supported the results obtained with FTIR, showing that the transition from primary cell wall synthesis to secondary cell wall synthesis occurs at or around 20 dpa. This study is the first to report on the use of the UATR‐FTIR and TGA to elucidate structural changes during cotton fiber development. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci, 2008

“…In this study the optimal fiber production in vitro by G. barbadense resulted when the phytohormones were used at 10 times the phytohormone concentrations used for G. hirsutum by the Beasley and Ting protocol. While the endogenous levels of ovular and/or fiber phytohormones have been measured by several investigators (Chen et al, 1996(Chen et al, , 1997Dugger and Sachs, 1987;Gokani et al, 1998;Nayyar et al, 1989), there has never been a direct comparison of phytohormone levels between G. hirsutum and G. barbadense.…”

Nearly 30 years ago the conditions for culturing immature cotton ovules were established to serve as a working research tool for investigating the physiology and biochemistry of fiber development. Not only has this tissue culture method been employed to characterize the biochemistry of plant cell expansion and secondary cell wall synthesis, but ovule cultures have contributed to numerous other aspects of plant cell physiology and development as well. In addition to basic studies on fiber development, cotton ovule cultures have been used to examine plant-fungal interactions, to model low temperature stress responses, to elucidate the pathways responsible for pigment formation in naturally pigmented fiber and to probe how cytoskeletal elements regulate cell wall organization. Success in rescuing Gossypium interspecific hybrids was dependent on ovule culture media formulations that could support early embryo development in ovulo. As tissues produced in culture are analyzed by increasingly more sophisticated techniques, there appear to be some differences between ovule growth in planta and ovule growth in vitro. Discerning how ovule culture fiber development is different from fiber development in field-grown plants can contribute valuable information for crop improvement. Cotton ovule cultures are an especially attractive model system for studying the effects of gravity on cell elongation, cellulose biosynthesis and embryo development and are excellent targets for examining transient expression of introduced gene constructs. With only minor modification, the procedure originally described by C. A. Beasley and I. P. Ting for growing cotton ovules in vitro will continue to be a useful research tool for the foreseeable future.
