Evolution and diversification of the momilactone biosynthetic gene cluster in the genus Oryza.

ABSTRACT: Plants are master chemists and collectively are able to produce hundreds of thousands of different organic compounds. The genes underlying the biosynthesis of many specialized metabolites are organized in biosynthetic gene clusters (BGCs), which is hypothesized to ensure their faithful coinheritance and to facilitate their coordinated expression. In rice (Oryza sativa), momilactones are diterpenoids that act in plant defence and various organismic interactions. Many of the genes essential for momilactone biosynthesis are grouped in a BGC. We applied comparative genomics of diploid and allotetraploid Oryza species to reconstruct the species-specific architecture, evolutionary trajectory, and sub-functionalisation of the momilactone biosynthetic gene cluster (MBGC) in the Oryza genus.
