A yellow pigment found in the seed of cotton plant Gossypium arboreum L. (Malvaceae), from the woody stems and stem barks of Puerto Rico s Montezuma speciosissima Sesse and Moc. (Malvaceae) and from the bark and the flowers of Thespesiapopulnea (Malvaceae) found in Africa, Asia and Pacific Islands [302-304, 323], gossypol (57), m.p. 166-167 °C, is a symmetrically substituted hexahydroxy-2,2 -binaphthalenedialdehyde derivative [303-308].

The seeds of the Gossypium arboreum cultivar and a hybrid contained less Mo than did other cultivars of cotton (Bhatt and Appukuttan, 1982). Recent studies by Shivashankar and Hagstrom (1991) showed that peas contained much higher Mo concentrations than cereals and com. They also reported that the hybrid cotton-lucerne (alfalfa) combination resulted in 50% greater Mo uptake than when followed by the combination of groundnut Arachis hypogaea L.) and wheat or by cluster beans. Cereal grains contained much less Mo in unfertilized plots than in Mo-fertilized plots (Table 5.3). 

Meier et al (1981) have described studies upon the synthesis of pi,3 and Pl,4-glucans in intact cotton fibres (Gossypium arboreum), where the effects of injury are minimised. Radioactively labelled sucrose was supplied to the cut petioles of fruit capsules as a pulse of 20 minutes duration and its fate was followed for 40 hours. The fruit capsules were harvested into boiling 80 per cent (v/v) methanol to stop any response to injury as they were broken open and their contents were extracted with methanol and dimethyl sulphoxide in succession. Sucrose and other small precursors entered the methanol extract.

Class I terpene synthases are highly a-helical proteins containing conserved aspartate-rich motifs. These motifs bind divalent metal ions (Mg " ) via salt bridges to form a trinuclear metal cluster that complexes the polyisoprenoid for diphosphate abstraction. Like ( )-selective prenyltransferases, type I terpene synthases exhibit one conserved aspartate-rich DDXX(D,E) motif, but instead of a second DDXXD on the opposite side of the active center, a consensus sequence of (N,D)D(L,I,V)X (S,T)XXXE (also termed NSE/DTE triad) is found here. One exception is the (-l-)-5-cadinene synthase from Gossypium arboreum that like prenyltransferases contains two DDXXE motifs [195].
