GOSSYPIUM speoes, including the currently cultivated varieties, contain pigment glands in the leaves and flower buds, but gland-free strains have been produced by using two genes from McMichael’s (7) gland-free stock. Though cotton plants do not require pigment glands for growth and reproduction, the presence of these glands containing gossypol might be of evolutionary significance. Gossypol ( [2,2’-binaphthalene] -8, 8’ dicarboxaldehyde, 1,1’,6,6",7,7’-hexahydroxy, 5,5’-diiosopropyl-3,3’ dimethyl), is toxic when consumed by nonruminant mammals (17) and by certain laboratory-reared insects (3). Conceivably, glands and gossypol in the leaves, flower buds, and seeds might have been a factor in effecting a differential survival of cotton plants.
