Based on a study of the expression of chromoplast-specific carotenoid-associated genes from cucumber corolla (CHRC and CHRD), a working model is presented wherein two major regulatory factors control carotenoid sequestration within the chromoplasts: (i) floral tissue-specific transcriptional regulators of chromoplasto- genesis; and (ii) post-transcriptional regulators related to the amount/type of sequestered carotenoids.
This model is supported by the major role transcriptional regulation was found to play in the temporal and spatial expression of the CHRC gene, and by the fact that phytohormones such as gibberellic acid (GA3), abscisic acid and ethylene also acted as transcriptional regulators of CHRC expression.
