{{DISPLAYTITLE:Specialized metabolism in Oryza}}Oryza is a genus in the Poaceae family of plants, of which Oryza sativa (cultivated rice) is a member. Oryza is a genus of 24 species, most of which are annual and some perennial grasses, which are found in tropical and swampy parts of Africa, Asia and Australia. Given its wide geographic range, there exists a substantial diversity of specialized metabolites (also called secondary metabolites) in the Oryza genus. Understanding this diversity can provide us solutions for mitigate crop losses due to disease and pest damage in rice, and boost agricultural production.[1]Anthocyanins and flavonols- Cyanidin 3-O-glucoside (I): Produced by purple pigmented rice
- Malvidin: Produced by purple pigmented rice
- Tricin
- Quercitin
- Kaempferol
- Apigenin
Carotenoids-- β-carotene (provitamin A)
- Lutein
- zeaxanthin
Hydroxycinnamic acids{{Empty section|date=December 2015}}Alkaloids- Benzoxazinoids
- Quinolone alkaloids
Phytoalexins- Sakuranetin: Increases rapidly under biotic and abiotic stress stimula including UV and pathogen attack.
- Naringenin
