Biochemical Analysis and Sensing Techniques

A number of genes are known to be involved in the production of anthocyanin in maize aleurone. Thin layer chromatography has been used to detect specific flavonoids associated with the recessive forms of these genes. The results obtained so far indicate that the genes C 1 , C 2 , R and Pr all act before the formation of flavonol in the biosynthetic pathway, that A 1 acts between flavanonol and 'flavenol' and that A 2 acts between flavenol and anthocyanidin. Light substitutes for the action of the C 1 gene in certain conditions and can be used to 'force' the system, causing a buildup of intermediate and side products beyond the C 1 controlled step. The C 1 gene probably controls a step between the C 9 stage and flavanone.
