Taiwanese scholars make promising discovery about corn reproduction

Taipei, Sept. 11 (CNA) Academia Sinica said Friday its scholars have identified a key protein function in corn reproduction, which may help improve crop quality. The findings were published in the latest edition of the scientific journal "The Plant Cell" under the names of Wang Chung-ju (???), an assistant research fellow at the Institute of Plant and Microbial Biology at Academia Sinica, and her research team. Wang and her research team found that a protein called DSY2 plays an important role in the reproduction of corn. The team discovered that DSY2, which is located on chromosome axes, is required during a specialized cell division to exchanges parts of DNA from paternal and maternal chromosomes to create a new combination. The recombination provides genetic diversity and is the molecular basis of crop breeding. By defining how DSY2 works during the reproduction, scientist can generate better DNA combinations to improve the quality of corn crops, generation by generation, according to Academia Sinica. The study could help address the food crisis across the world, as the corn is a staple for more than 1.2 billion people, it said. The study has won the recognition of the U.S. federally funded informatics service on maize, the MaizeGDB Editorial Board, which has nominated it as "noteworthy maize primary literature."
