Distinct metabolic pathways drive monoterpenoid biosynthesis in a natural population of Pelargonium graveolens.

abstract：:The composition of carotenoids, along with anthocyanins and chlorophyll, accounts for the distinctive range of colour found in the Actinidia (kiwifruit) species. Lutein and beta-carotene are the most abundant carotenoids found during fruit development, with beta-carotene concentration increasing rapidly during fruit m...
