• GmCCD4 controls carotenoid content in soybeans

    9 days ago - By Wiley

    Summary
    To better understand the mechanisms regulating plant carotenoid metabolism in staple crop, we report the map‐based cloning and functional characterization of the Glycine max carotenoid cleavage dioxygenase 4 gene, which encodes a carotenoid cleavage dioxygenase enzyme involved in metabolizing carotenoids into volatile β‐ionone. Loss of GmCCD4 protein function in four Glycine max increased carotenoid content mutants resulted in yellow flowers due to excessive accumulation of carotenoids in flower petals. The carotenoid contents also increase three times in gmicc1 seeds. A...
