Abstract：OST1 gene plays important roles in ABA signaling,abiotic stress response and growth and de-velopment of plant.However,the study on melon OST1 has not been reported at present.In this paper,two novel OST1 genes orthologous to Arabidopsis OST1 were identified through comparative genomics method. Their molecular features,evolution,and cis -elements were systematically analyzed.The results showed that these two melon OST1 genes were located on different chromosomes,and both had 9 introns.The sequence iden-tity of their encoded proteins was 80.38%,and they were highly conserved with the corresponding cucumber homologues.There were multiple cis -elements response to different hormones and stresses in their up -stream sequences,which suggested they might have multiple roles in biological process.This study laid a foundation for further functional dissection of melon OST1 genes in abiotic stress response,growth and development.
