A research team led by Professor Murata of the Institute of Resources and Botany, Okayama University in Japan announced on the 25th that they have succeeded in artificially producing chromosomes with genetic information in plant cells. This result will help develop new crop varieties. The research team used Arabidopsis to use the "top-down analysis" method to manipulate the original chromosomes in the cells and adapt them to produce circular artificial chromosomes smaller than the usual chromosomes. Even self-pollinated seeds have inherited more than 40% of this artificial chromosome. The research team said that it is the first time in the world to use plants to create artificial chromosomes that can be inherited by the next generation. By implanting specific genes into this chromosome, new plants and crop varieties that are resistant to pests and diseases can be cultivated. "This technology can also be used to implant pest-resistant and lodging-resistant genes during rice growth," Murata said. The papers on this achievement have been published in the British Journal of Botany.
