Genes useful for biofortification through mobilisation of multiple nutrients and enhancement of physiological parameters in plants.

Gene	Transgenic Plant	Response	References
Suppression of DET1 (De-etiolated 1) by RNAi	Solanum lycopersicum	Improves both carotenoid as well as flavonoid content simultaneously	(Davuluri et al. 2005); (Wirth et al. 2009); (Song et al. 2014); (Ramireddy et al. 2018)
NAS (Nicotianamine synthase) and ferritin	Oryza sativa	Increase in mineral content of Fe and Zn
Alternanthera philoxeroides KUP3 (ApKUP3)	Oryza sativa	Enhanced K+ nutrition and drought tolerance in transgenic plants. Increased the net photosynthetic rate, activities of superoxide dismutase, peroxidase, and ascorbate peroxidase.
Cytokinin oxidase / dehydrogenase gene (CKX)	Hordeum vulgare	Improved nutrient efficiency, and biofortification. Improved tolerance against drought
