Annotated Information
Function
- Carotenoids are a group of approximately 600 known organic pigments naturally found in plants; around 50 of these, including β-carotene, exhibit provitamin A activity[1].β-carotene is the most abundant source of provitamin A in the human diet.
- As a provitamin A compound, β-carotene has been the focus of many scientific studies and public health interventions. For example, many past and ongoing public health interventions have aimed to use β-carotene supplementation as a way of addressing vitamin A deficiency that causes symptoms ranging from night blindness to those of xerophthalmia and keratomalacia, leading to total blindness. In addition, due to β-carotene’s character as a highly active antioxidant, numerous scientific trials have focused on the potential for utilizing β-carotene in the prevention of cancer and other chronic diseases[2].
- Rice (Oryza sativa), a major staple food, is usually milled to remove the oil-rich aleurone layer that turns rancid upon storage, especially in tropical areas. The remaining edible part of rice grains, the endosperm, lacks several essential nutrients, such as β-carotene (provitamin A).
Expression
Rice is a staple food and no rice cultivar has the capacity to produce β-carotene （provitamin A） in the endosperm tissue(14). Histochemical reactions clearly revealed the accumulation of β-carotene in the endosperm of transgenic seeds of indica rice (Oryza sativaL.) in comparison with non-transgenic control where no β-carotene could be detected(Figure 1). Three genes, namely phytoene synthase (psy), phytoene desaturase (crtI), and lycopene cyclase (lcy) are involved in the biosynthesis of β-carotene。
