Japan has successfully grown a low-absorbing variety of Cadmium

The American Plant Cell magazine recently reported that researchers at Okayama University, Japan, have successfully cultivated a rice variety that hardly absorbs Cadmium heavy metals, by limiting the role of a gene. in their bodies.

Through the study of the mechanism of heavy metal absorption in the soil of rice, scientists have noticed a gene called Nramp5. They made the outer skin of the rice stem and Nramp5 gene not effective, then cultivated in areas where the soil is heavily polluted. The results showed that the content of Cadmium in rice seeds after harvest only accounted for 1/10 compared to normal rice plants.

However, if the Nramp5 gene does not work, the element of manganese absorption capacity necessary for the growth of rice is also significantly reduced. This leads to its harvest output of only 20% compared to normal.

The researchers' next research plan is to improve the combination of new rice varieties and to control the absorption of metal elements of rice.

Cadmium is a heavy, toxic metal element. Residents living in areas exposed to Cadmium will be at high risk of being exposed to Cadmium due to the use of locally produced vegetable and rice products.

Currently bone pain is one of the four major diseases in Japan diagnosed by Cadmium infection.
