Capsaicinoids are responsible for the pungency in species. These are synthesized by the Capsaicin synthase (CS) encoded by the gene, which catalyzes the transference of an acyl moiety from a branched-chain fatty acid-CoA ester to the vanillylamine to produce capsaicinoids. Some gene copies have been identified on the genome.

Unlabelled: Lycopene cyclases (LCYs) are a key branching point in regulating the carotenoid biosynthesis pathway in plants. L. is characterized by the presence in its seed of bixin, an apocarotenoid of significant importance in the food, pharmaceutical, and cosmetic industries.

The genus includes species that are phytopathogenic fungi, which infect different species of Poaceae, such as rice and sorghum. However, few isolates have been genetically characterized in North America. The current study addresses this lack of information by characterizing an additional 57 strains of three grasses (, and ) from two distant regions of Mexico.

Diverse morphological, cellular and physiological changes occur during seed maturation in when the seed tissues form specialized cell glands that produce reddish latex with high bixin amounts. Transcriptomic profiling during seed development in three accessions (P12, N4 and N5) with contrasting morphologic characteristics showed enrichment in pathways of triterpenes, sesquiterpenes, and cuticular wax biosynthesis. WGCNA allows groups of all identified genes in six modules the module turquoise, the largest and highly correlated with the bixin content.
