Little is known about the factors regulating carotenoid biosynthesis in flowers. Here, we characterized the REDUCED CAROTENOID PIGMENTATION2 (RCP2) locus from two monkeyflower (Mimulus) species, the bumblebee-pollinated species Mimulus lewisii and the hummingbird-pollinated species Mimulus verbenaceus. We show that loss-of-function mutations of RCP2 cause drastic down-regulation of the entire carotenoid biosynthetic pathway. The causal gene underlying RCP2 encodes a tetratricopeptide repeat protein that is closely related to the Arabidopsis (Arabidopsis thaliana) REDUCED CHLOROPLAST COVERAGE proteins. RCP2 appears to regulate carotenoid biosynthesis independently of RCP1, a previously identified R2R3-MYB master regulator of carotenoid biosynthesis. We show that RCP2 is necessary and sufficient for chromoplast development and carotenoid accumulation in floral tissues. Simultaneous down-regulation of RCP2 and two closely related paralogs, RCP2-L1 and RCP2-L2, yielded plants with pale leaves deficient in chlorophyll and carotenoids and with reduced chloroplast compartment size. Finally, we demonstrate that M. verbenaceus is just as amenable to chemical mutagenesis and in planta transformation as the more extensively studied M. lewisii, making these two species an excellent platform for comparative developmental genetics studies of closely related species with dramatic phenotypic divergence.
