Golden Rice Mutagenesis Top Journals

In Golden Rice, two genes are inserted into the rice genome by gene-splicing , which might not are possible by traditional breeding, to restart the carotenoid biosynthetic pathway resulting in the assembly and accumulation of β-carotene within the grains. The intensity of the golden color is an indicator of the concentration of β-carotene within the endosperm. Since a prototype Golden Rice was developed in 1999, new lines with higher β-carotene content are generated.The high selection pressure applied in rice breeding since its domestication thousands of years ago has caused a narrowing in its genetic variability. Obtaining new rice cultivars therefore becomes a serious challenge for breeders and developing strategies to extend the genetic variability has demanded the eye of several research groups. Understanding mutations and their applications have paved the way for advances within the elucidation of a genetic, physiological, and biochemical basis.
