Wit h continuous global warming,drought stress is increasingly becoming a serious threat to food production.Exploring the mechanism of resuscitation plants to withstand extreme drought stress and accumulating drought-related gene resources play an important role in basic research of plant adaptation to stress and sustainable agricultural development.B.hygrometrica is widely distributed in mountainous areas of China,and it is a representative species of resuscitation plants.And high quality whole genome sequence of B.hygrometrica is available for analysis.In this study,the early light-inducible protein(ELIPs)gene family in the B.hygrometrica genome was excavated and analyzed.The number of early light-inducible protein(ELIPs)genes in the B.hygrometrica genome was much higher than that of other plants(Arabidopsis,rice,pepper and tomato).Phylogenetic analysis showed that early light induced protein(ELIPs)gene sequences had high plant specificity.This might suggest that early light-inducible protein(ELIPs)genes would play an important role in the adaption of different plants to their respective growth environments.The gene expression analysis of the B.hygrometrica leaves in different degrees of drought showed that part of the B.hygrometrica early light induced protein(ELIPs)genes showed a strong response to drought treatment.Different early light-inducible protein(ELIPs)genes showed three different response patterns.These results might indicate that the early light-inducible protein(ELIPs)gene of B.hygrometrica was involved in drought stress response,and there were delicate regulatory mechanisms to control the expression contents of different early light-inducible protein(ELIPs)genes.
