According to Science Network, on January 12, hosted by the Chinese Academy of Sciences and the Chinese Academy of Engineering, organized by the Working Bureau of the Faculty of the Chinese Academy of Sciences, the General Office of the Chinese Academy of Engineering, and China Science News, and voted by academicians of the Chinese Academy of Sciences and the Chinese Academy of Engineering, the 2022 China's top ten scientific and technological progress news and the world's top ten scientific and technological progress news were announced in Beijing on January 12, 2023
.
The research results of Professor Yan Jianbing and Professor Yang Xiaohong and Professor Li Jiansheng of China Agricultural University "Discover the key genes for increasing corn and rice yield" were selected as China's top ten scientific and technological progress news
in 2022.
This achievement is the only achievement
in the field of agricultural science that has been selected as one of China's top ten scientific and technological progress news.

Maize, rice and wheat are the three most successfully domesticated crops to date, providing more than 50% of humanity's energy intake
.
Due to their different domestication regions, ancestors, and morphological habits, whether their domestication process follows a common genetic law has long been debated
in the scientific community.
On March 25, 2022, Science magazine published online the research paper of the joint team of our professor Yan Jianbing and professor Yang Xiaohong / Li Jiansheng of China Agricultural University.
After three generations of scientists and 18 years, the research has found that the corn gene KRN2 and the rice gene OsKRN2 are selected for convergence and regulate the yield
of maize and rice through similar pathways.
The team further elucidated the genetic laws
of convergent evolution at the genome-wide level.
It is reported that this achievement not only reveals the mechanism of homologous gene convergence evolution of maize and rice to increase the yield of maize and rice, provides valuable genetic resources for breeding, but also provides an important theoretical basis
for the analysis and breeding application of key control genes for agronomic traits, as well as the rapid redomestication or de novo domestication of other excellent wild plants.

The annual selection has been held 29 times
so far.
After the selection results were widely reported by the news media, they had strong repercussions in the society, enabling the public to further understand the dynamics of scientific and technological development at home and abroad, and played a positive role
in popularizing science and technology.
