New Maize Varieties Producing Decomposable Mycotoxins on Day

Japanese researchers use genetically modified technology to cultivate new corn varieties that can "self detoxify" mycotoxins.
A toxin produced by a red mold found in molds can cause abnormalities in the reproductive system of livestock, resulting in abortions and stillbirths. This mold can infect major crops such as corn and wheat, especially affecting the reproductive system of pigs, and it is difficult to prevent and disinfect. Corresponding treatments require mold inspection and antidote. Researchers in the process of searching for mycotoxin-degrading enzymes found a catabolic enzyme on another mold, and then injected the genomic DNA of the degrading enzyme into the maize gene, and confirmed that the offspring of the GM corn were also decomposed. Toxin's ability. The researchers used a dose of toxin that was 5000 times higher than the naturally occurring mycotoxin concentration to test and found no mycotoxin in the harvested transgenic maize seeds. However, a high concentration of mold was detected in the same contaminated control corn seeds. toxin.
Researchers believe that the development of new technologies that can "self-detoxify" corn varieties is a simple and inexpensive method of preventing mild mold from animal feed, and is very easy to spread.
