“…In this study, all the interpecific hybrids [2(G. Content of TA vary among accessions of the same species and also by stage of plant growth, the environmental conditions (Stipanovic et al 1988;Altman et al 1989), and the organ type and size (Hedin et al 1991). The TTA content we measured for the three diploid species investigated and G. hirsutum are three-to ten-fold lower than the data obtained by Altaf et al (1999) for the same species.…”

“…High Performance Liquid Chromatography (HPLC) analysis results showed that gossypol is the main TA in seed but not in foliar glands. Hemigossypolone and the heliocides constitute up to 90% of the total TAs in leaves and up to 45% in flower buds (Altman et al 1989;Stipanovic et al 1988). …”

Expression of the “glanded-plant and glandless-seed” trait of Australian diploid cottons in different genetic backgrounds

et al. 2008

The expression of the "glanded-plant and glandless-seed" trait was assessed using High Performance Liquid Chromatography (HPLC) analysis methods in different Gossypium hybrids obtained by crossing Australian diploid cottons and various diploid and tetraploid species. Significant variation in the gossypol content in the seed was observed among the analyzed genotypes. HPLC data demonstrated that the gossypol synthesis repression mechanism in the Australian diploid species belonging to C and G genomes was dominant but did not confirm its preferential functioning against A genome species bearing GL 2 locus. About 10% of the produced seeds had total gossypol content lower than the limit imposed by the World Health Organisation (600 ppm) for the use of cotton flour in food and feed. HPLC analysis of the terpenoids aldehyde (TA) contents in the aerial parts of the hybrids showed important qualitative and quantitative variability. This result could indicate a certain separation between pigment gland morphogenesis and terpenoid synthesis mechanisms in cotton.

“…One reason has been the lack of assay methods to easily separate and quantify the TAs gossypol, HGQ and heliocides which are predominant in "green" tissues such as leaves, bracts, bolls, calyces and stems. High performance liquid chromatography (HPLC) based methods have been developed to separate and quantify TAs in "green" tissues and "white" tissues such as petals or roots [4] [22], and recent modifications to the original methods currently allow economical large scale screening for TAs in all plant tissues [12] [23].…”

Cotton (Gossypium hirsutum L.) has epidermal glands containing terpenoid aldehyde (TA) compounds that protect the plant from pests and diseases. One TA, gossypol, has two forms (+) and (−) that are present in varying amounts. This study evaluated the variation in roots for TA compounds and how environment affected the levels of these compounds. Similar to seed, gossypol was the predominant TA in roots. No heliocides were detected with only trace amounts of other TAs, such as hemigossypolone or hemigossypol, detected in a few lines. Among the glanded lines, there were significant differences in gossypol content. Percent plus gossypol was consistently 4% -10% higher in roots than seed. One line, "Mac7", had 12 -14 ug/mg gossypol in roots and 18 ug/mg in seed as well as >90% (+) gossypol in both roots and seed. Unlike other tissues in glandless cotton, the roots of glandless lines consistently produced detectable amounts of gossypol with 77% to 82% in the (+) form. Multi-year field tests showed that although gossypol levels in the roots were more affected by insect pressure or other environmental conditions than seed, there was selectable variation in upland cotton for root gossypol content. Unlike other parts of a glandless plant, the roots retained a functioning biochemical pathway for gossypol production.

RESUMO -Um experimento foi conduzido para verificar os efeitos da inclusão de três níveis (0, 8 e 12%) de farelo de algodão contendo 36% de PB (FA 36 ) e três níveis (0, 20 e 40 g/100 kg de ração) de sulfato de ferro (FeSO 4 Effects of feeding cottonseed meal with or without iron addition for starting piglets (15-30 kg)ABSTRACT -A trial was carried out to evaluate the effects of increasing levels (0, 8 and 12%) of cottonseed meal 36%(CM 36 ) and three inclusion levels (0, 20, and 40 g/100 kg) of ferrous sulfate -FeSO 4 (12% of CM diets) on the performance, plasma urea nitrogen (PUN) and hematological values of starting pigs (15-30 kg). Eighty pigs, barrows and females, averaging initial body weight of 14.81 ± 1.72 kg were allotted to a complete randomized block design with five treatments (0CM, 8CM, 12CM, 12CM+20FeSO 4 , and 12CM+40FeSO 4 ) and five replicates with two or three piglets per experimental unit. There was no effect of increasing CM 36 levels and ferrous sulfate addition on piglet performance.
