摘要：

Many studies have showed plant VQ gene family plays an important part in response to abiotic and biotic stresses. At present, VQ protein family has been found successively in many plants, however, there have no detailed characterization and expression profiles of VQ gene family in muskmelon. Thus, the author probed into genome-wide identification, characterization and expression pattern under various hormones and abiotic stresses. Thirty CmVQ genes were classified ten groups according to orthologous of Arabidopsis VQ genes and dispersedly distributed on 11 chromosomes except for chromosomes 5 and 9. Majority of CmVQ members contained 300 amino acids or less, and were predicted to localize in the nucleus and had no intron. Many cis -elements in response to different stresses and hormones were found in the promoters of CmVQ genes. Gene ontology analysis displayed that 60% CmVQ genes participated in response to stimuli. Quantitative real-time PCR displayed that numerous CmVQ genes showed either positively or negatively regulated expression patterns under hormonal treatments and abiotic stresses. In summary, this research offers a general introduction to melon VQ genes and will contribute to the molecular breeding for resistance to stresses, as well as deeper inquiry on the biological functions of the VQ proteins.
