Flavonoid biochemical pathways, the end-products and their functions, molecular genetics, and the structural and regulatory genes in maize and teosinte are reviewed. Inadequate biochemical identifications and terminology problems are emphasized. Tissue-specific expressions of flavonoids in four tissues or organs of maize: anthers, pericarp, aleurone, and vegetative parts are discussed. Genes of the female inflorescence, considered critical in the evolutionary conversion of the teosinte vegetative body and floral structures into that of maize, have been studied. However, only a few genes of the C1 regulatory family controlling anthocyanin formation have been identified. Major biochemical and physiological data are still needed to understand this fascinating evolutionary sequence. |
