Abstract: Although genes that encode most enzymes
of the carotenoid pathway in higher plants have been identified, the
regulatory mechanisms that govern the synthesis and accumulation of
carotenoid pigments are still obscure. Recent findings relevant to two
aspects of carotenoid pathway control are reviewed: availability of
substrate and pathway branching. Experimental approaches that are likely
to enhance our understanding of carotenoid pathway regulation are also
described.
