Genome-wide Identification and Expression Analysis of CHYR Gene Family in Rice
CHYR family,which is a group of genes containing CHY zinc finger domain and RING finger domain,are widely involved in plants response to adverse conditions.In this study,a total of 7 rice CHYR genes were identi-fied by using bioinformatics.Phylogenetic analysis depicted that the 7 rice CHYR genes could be further divided into 3 subfamilies.Furthermore,genes in different groups were conserved in term of gene structure and conserved motif.Chromosome location analysis showed that 7 OsCHYR genes were distributed on 5 different chromosomes.Further syntenic analysis revealed that rice and maize showed higher gene homology.Rice tissue expression data analysis in-dicated that OsCHYR genes were highly expressed in all rice detected tissues,and induced by salt,drought and cold stress.Protein-protein interaction analysis showed that OsCHYR may function by interacting with transcription fac-tors,ubiquitin building enzyme and ubiquitin ligase enzyme.
