Following corn, wheat, and rice, potato represents one of human’s most important crops. But despite its popularity it has its downsides which are the presence of toxic substance known as steroidal glycoalkaloids, mainly solanine and chachonine, which in some cases make the plants inedible. The researchers have discovered the cholesterol however in small amount is used to synthesis the glycoalkaloid toxins. Up to know there were many attempts to reduce such toxin substances but it has resulted in an increase in other substances that are equally dangerous.

As a result Japanese researchers have decided to reduce the cholesterol in potatoes which as contributed in synthesizing toxic substances in potatoes. They have discovered an enzyme called sterol side chain reductase 2 (SSR2) is responsible for the synthesis of cholesterol in potatoes which has opened a way for reducing cholesterol in them consequently making them less toxic. To verify the result, they have performed gene silencing in order to create a variety of potato without SSR2 gene, where they were able to reduce the levels of toxic glycoalkaloids by about 10 percent without affecting the harvest yield of the plants. The researchers will leverage their findings to determine whether the same enzyme could be targeted in other plants that produce toxic or beneficial substances derived from cholesterol.
