As soon as we say apple, a sweet red fruit comes to our eyes. We have come to love green apples a little less. But did you know that environmental pollution has greatly increased the risk of extinction of these red apples?
Not only red or green, but also light yellow, striped apples can be found in the store. These are the hundreds of apples that started in what is now Kazakhstan. The mountains of this place draw the border of western China. The apple is still born in the place. People become food for animals. Makes the air fragrant. However, these wild apple trees have declined by 90 percent in the last 50 years.Why? Of course, as always, human development is behind this change. As a result, the future of this whole place and the wild apple is uncertain.
Why is the color of apple red?
Apples come in many colors. But why? And this is the red color of the apple, that is why it is made? According to scientists, the red color of apples is mainly due to some genes on its surface. David C., a geneticist at New Zealand's Plant and Food Research. Many enzymes work together to change the color of apples to red. This produces anthocyanins. You see, not just apples, but the sweet reddish color of sweet potatoes, the color of grapes and the color of palm fruit - these are the ingredients behind it all.
The amount of this enzyme determines the amount of a specific protein. Whose name is MYB 10. To put it bluntly, if there is more than 10 MYB somewhere, the skin color of other fruits including apples will become more red. Even in the case of apples whose skin you see red in some parts and green or yellow in others, the amount of MYB10 protein is comparatively higher in the reddish part.
Of course, in addition to all this, temperature also works behind color determination. According to David, for the apple to be completely red in color, the surrounding environment must be cool. This is because when the temperature rises above 40 degrees Celsius, the amount of MYB 10 and anthocyanin is destroyed. The expert spoke of Spain as an example. There, the reddish apple service turned pale after a warm July. As the temperature warms, the chances of the apples turning red also decrease.
