Abstract:

In order to study the characteristics of melon(Cucumis melo L.)GolS family genes and their responses to low temperature stress,members of the melon GolS family of genes were identified using bioinformatics. The chromosomal locations,evolutionary relationships,genetic structure,promoters,cis-acting elements,tissue-specific expressions and expression patterns under low temperature stress were predicted using bioinformatics. After exhaustive analysis,12 CmGolS genes were successfully identified and found to be unevenly distributed across nine chromosomes. The analyses of phylogenetic showed that these genes were divided into 5 groups. Physicochemical analysis showed that all CmGolS proteins were hydrophilic proteins. The CmGolS genes were highly conserved and they have 2-5 introns. These genes contain conserved motifs“DxD”“HxxGxxKPW”and many cis-acting elements,which related to stress and hormones such as gibberellin,auxin and abscisic acid. In addition CmGolS genes have tissue specific expressions,most of them are expressed in male flowers. And the relative expression of most of them show a significant up-regulation trend under low temperature stress that indicated CmGolS genes can actively participate in the processes of responding to low temperature stress.

Key words: melon, galactinol synthase, bioinformatics analysis, cold stress, expression analysis
