Abstract：As important type of ceruloplasmin in organism，laccase plays important role in plant growth
regulation and resistance adv ersity．In this study，based on the genome and transcriptome of Amaranthus
tricolor L.，the laccase gene family members of Amaranthus tricolor L.（AtrLAC）were identifi ed．Online
software was used to predict the bioinformatics information．Meanwhile，the gene expression pattern was
analyzed according to TPM of transcrisptome data．The results indicated that a total of 19 LAC genes were screened from Amaranthus tricolor L. genome，the AtrLAC protein ranged from 118-1 191 aa in length，the molecular weight was in the range of 13.05-135.10 kD，and the isoelectric point was about 6.49-9.85．Most of AtrLACs were hydrophilic，alkaline and stable proteins．The subcellular localization was predicted that the most of AtrLACs were outside the cell membrane or on the plasma membrane．The 19 LAC members of Amaranth tricolor L. and the 17 LAC members of Arabidopsis thaliana were clustered into 6 groups according to the phylogenetic tree．The TPM analysis showed that the expression of AtrLACs was diff erent under diff erent treatments．Among them，AtrLAC7 might play an important role in betalain synthesis，hormone regulation and light condition in betalain．
