According to the latest news of the Chinese Academy of Agricultural Sciences, the institute's bee genetics and breeding innovation team in the Study of the Chinese Bee (Middle Bee) population genomics, through the observation and analysis of the bee population in 18 regions of China, found that it has a higher genetic polymorphism, the degree of inter-group differentiation is high, some groups differentiation reached the subspecies level, breaking the original understanding of the international bee population as a type, and systematically revealed the group structure, evolution and adaptability of the middle bee.
related research published online in Molecular Biology and Evolution.
, the Chinese bee is widely distributed, covering a variety of climate areas and terrain, is an important genetic resources in China.
its group diversity has been seriously affected and needs to be protected.
and in the past limited by research methods, the knowledge of the middle bee population is very limited.
the team's analysis of the genetic structure of the middle bee population found that populations in islands and mountainous areas had higher genetic differentiation and lower genetic polymorphism, and there was a strong genetic flow in plain populations.
therefore, the protection of bees in plain areas should take into account the effects of gene flow. further research
found that terrain barrier promotes differentiation among its populations, while geographic distance has less influence on genetic differentiation.
, it is necessary to explore the more complex terrain areas such as the Qinghai-Tibet Plateau and explore the resources of bee species.
this study is of fundamental significance to further protect the genetic resources of bees in China.
the research has been supported by the Scientific and Technological Innovation Project of the Chinese Academy of Agricultural Sciences, the Bee Industry Technology System of the Ministry of Agriculture and Rural Affairs, etc.
