Carotenoids are an abundant group of isoprenoid pigments present in all photosynthetic organisms and responsible for the typical yellow, orange, or red coloration exhibited by many flowers, fruits, and vegetables. Besides their many functions in plants, these pigments are also essential components in human and animal diet. Within the past three decades, genes encoding all of the enzymes required for the biosynthesis of these indispensable pigments have been identified and characterized in higher plants, primarily as a result of integration of comparative genomics, biochemical genetics, and molecular approaches in the model plant Arabidopsis thaliana and cyanobacterium Synechocystis PCC6803. Mutant analysis and transgenic studies in these and other systems have established a foundation for understanding the function, regulation, and evolution of individual genes and enzymes. The aim of this chapter is to review advances in the structure, function, and evolution of these genes and enzymes, as well as the molecular mechanisms regulating carotenoid biosynthesis in higher plants.

AB - A new structural gene, carG, involved in the biosynthesis of carotenoids in the fungus Mucor circinelloides was isolated by heterologous hybridisation, using a probe derived from the Gibberella fujikuroi ggs1 gene. Functional analyses in Escherichia coli showed that the encoded protein has geranylgeranyl pyrophosphate (GGPP) synthase activity. A comparison of the deduced protein with other GGPP synthases suggested that the carG gene might have evolved from other larger genes present in some fungi. The analysis of carG mRNA accumulation after blue light irradiation showed that the expression of this gene is up-regulated by blue light, as happens with the other structural genes involved in carotenogenesis in M. circinelloides. Analysis of the promoter region revealed the presence of several APE-like sequences, which participate in the blue-light regulation of the expression of different fungal genes. These sequences are also present in the above-mentioned Mucor genes and strongly support the idea that this gene plays an important role in the regulation of carotenoid synthesis, despite belonging to a more general metabolic pathway.
