Advances in non-coding RNA of caste determination and labor division in eusocial insects
Eusocial insects are one of the most representative subjects for the study of phenotypic plasticity.Due to their cooperation and labor division,the whole group can efficiently adapt to the variable environments and maintain the reproductive success of the population.Although sharing the same genome,eusocial insects always exhibit different caste structures and labor division,which are controlled by both environment factors and genetics.Epigenetic genetics has been recognized as the main mechanism for remodeling gene expression in response to environmental conditions.Non-coding RNA(ncRNA),one of functional RNAs that widely involved in organismal life activities,plays an important role on caste determination and labor division in eusocial insects.This article reviewed the research progress on the mechanisms of ncRNAs,including microRNA(miRNA),long non-coding RNA(IncRNA),circular RNA(circRNA),and PIWI-interacting RNA(piRNA)in honeybees,ants and termites.It deepens the understanding of the molecular basis in eusocial insects,and also provides new perspectives on pest control.
