Identification and Expressions of GRF Genes in Artemisia argyi
[Objective]Growth-regulating factor (GRF) genes in Artemisia argyi were identified and analyzed.[Method]Bioinformatic analysis on the physiochemical properties,structure,and evolution of the GRF genes,as well as their expressions in different tissues under stresses,of A.argyi was conducted using qRT-PCR.[Result]Seventeen AsGRFs were hydrophilic proteins in the phylogenetic evolutionary tree of 4 subfamilies.Those genes of same clade in the evolutionary tree contained a similar or same conserved motif.The members were randomly distributed on 11 chromosomes with promoters of multiple stress-and hormone-responsive elements and one that varied in the response to salinity.The tissue-specific expressions of the genes,including AaGRF05,AaGRF06,AaGRF11,and AaGRF14,peaked in 12h after being exposed to abscisic acid,indoacetic acid,salicylic acid,or methyl jasmonate.[Conclusion]The GRF genes associated with the growth and stress regulation of A.argyi were identified,and relevant bioinformatics obtained.
