Gossypol biosynthesis in cotton revealed through
21 Gossypol plays an important role in defense mechanism of Gossypium species and the 22 presence of gossypol also limits the utilization of cottonseeds. However, little is 23 known about the metabolism of gossypol in cotton plant. Here, Detection on the 24 dynamic tendency of gossypol content illustrated that at the germination stage, the 25 main source of gossypol was cotyledon, and at the la...
متن کاملGossypol Content of Cotton Free Commercial Feed for Dairy Cows
Gossypol is a yellow pigment occurring in all parts of cotton plants, with the highest levels found in seeds, and it exhibits a variety of toxic effects. Few data are available on the content of gossypol in the commercial complementary feed and in feed raw materials. The present study was focused on the investigation of the presence of free gossypol in commercial complementary feed not containi...
متن کاملSpodoptera exigua modulates gossypol biosynthesis in cotton Gossypium hirsutum
Cotton plants induce high levels of gossypol in response to herbivore damage. However, little is known about the mechanisms by which insect herbivory modulates gossypol biosynthesis in cotton plants. Here, we report the mechanism by which herbivore damage or insect-originated elicitors modulate the biosynthesis of gossypol and jasmonic acid (JA) in plants. Spodoptera exigua larval-damaged (HD) ...
متن کاملInhibition of elicitor-induced phytoalexin formation in cotton and soybean cells by citrate.
Addition of an elicitor preparation from Verticillium dahliae to soybean or cotton cell suspension cultures induces the formation of the phytoalexins, glycelollin or sesquiterpene aldehydes, respectively. Recent work (PS Low, PF Heinstein 1986 Arch Biochem Biophys 249: 472-479) has shown that the induction of phytoalexin biosynthesis in these cells is preceded by rapid changes in the plant cell...
متن کاملStereoselective coupling of hemigossypol to form (+)-gossypol in moco cotton is mediated by a dirigent protein.
The terpenoid gossypol, a secondary metabolite found in the cotton plant, is synthesized by a free radical dimerization of hemigossypol. Gossypol exists as an atropisomeric mixture because of restricted rotation around the central binaphthyl bond. The dimerization of hemigossypol is regiospecific in cotton. In the case of some moco cotton, the dimerization also exhibits a high level of stereose...
