Recently , under the leadership of the Institute of Bee Research of the Chinese Academy of Agricultural Sciences and in cooperation with many domestic and foreign scientific inquiry institutions , the high-pitched - quality reference genome chronological succession of 16 species of domestic bumblebees in China have been suck for the first meter . Based on the sequences , comparative genomics studies have been lead and the molecular mechanism of bumblebee genome development has been let on . The recognition of genes touch to the ecological adaptability and behavior characteristics of bumblebee cater valuable genetical resources for the genetic improvement of native bumblebee in China . refer enquiry effect were bring out online in " Molecular Biology and Evolution " .

According to the researcher Sun Cheng , bumblebees are important pollinator and play a immense persona in the pollination of crops grown in greenhouses . They are excellent pollinator of many plant , especially Solanaceae crops . cause use of bumblebee to pollinate crops grown in greenhouses can not only increase yield but also improve fruit quality . At nowadays , the bumblebees identified worldwide let in 15 subgenus and about 250 coinage in total . China is the country with the richest bumblebee species resources in the mankind , and 125 species have been place . However , in China , presently , the bumblebees for pollenation used by the crops in greenhouses are highly dependent on imported humblebee , and these introduce bumblebees have endangerment of biological encroachment . Therefore , cultivating native pollinating bumblebee species is of great import for promoting the unripe and sustainable development of USDA in China and maintain the national ecologic environment .

The research team found through the sequencing of the whole genome of these 16 species of bumblebees in China and the comparative genomics subject field of the whole humblebee genus , the chromosomal structure of these bumblebee is very stable , and some more chromosomal structural changes only occurred in leechlike bumblebee . transposon are the chief factor to determine the size of the bumblebee genome , and there is evidence shown that transposons are involved in the formation of bumblebee factor write in code realm and regulatory region . The inner structure of bumblebee genes is relatively stable but the boundaries of factor are variable . This is because arrest codons of bumblebees can not efficaciously cease protein translation in many cases ; the genetical tree of humblebee is inconsistent with the species tree . This solvent evoke that future studies of bumblebees should be establish on independent genetic Tree ; the genetic variations pertain to traits such as bumblebee alimentation preference , adaption to in high spirits ALT , insecticide underground , and outside morphology were identified . The enquiry further analyzed the genome sequence of the native bumblebee in China and identified the genetic groundwork of excellent trait , which can provide a theoretical basis for the genteelness of aboriginal pollinating bumblebee species in China .

The research was funded by the Science and Technology Innovation Project of the Chinese Academy of Agricultural Sciences , the National Natural Science Foundation of China , and the Basic Research Fund of the Central Public Welfare Research Institute .
