Australian researchers discover a gene that controls the color of the apple. This gene controls compounds called anthocyanins that give red color to the apple.
To find the gene it has been taken into account that it is activated with light, since the apples are reddened by the effect of sunlight (the apples that grow in the dark or in the closed shade do not turn red). On the other hand, different apple varieties have been analyzed, focusing on the production of anthocyanin of green and red apple varieties to find the gene.
Gene discoverers ensure that from now on the apple color will be controlled and produce 'good-looking' apples. The consumer chooses the apple and it is convenient for apple producers and sellers to look attractive. However, anthocyanins that give red to apple are antioxidants and therefore healthy.
