Transcriptome Analysis, CmMYB1 Gene Clone From Cucumis Melo L. And Its Functional Roles Under Salt Stress
MYB TFs plays an important role in plant adaptation to abiotic stress, especially in response to salt stress. Preliminary research found that the stress resistance of the two melon varieties ‘M15’ and ‘baogua’ are quite different. To this end, we compared the transcriptomes of ‘M15’ and ‘baogua’. Transcriptome analysis found that the expression levels of 12 MYB transcription factors were significantly different between the two varieties.CmMYB1 gene was cloned from muskmelon (Cucumis melo L.), and the subcellular localization results showed that CmMYB1 was expressed in the cytoplasm and nucleus. Transform CmMYB1 gene into Arabidopsis thaliana, observe T3 phenotypes during the vegetative and reproductive growth periods.The results showed that the transgenic A. thaliana phenotype did not change significantly compared with the wild type . After treatment with 200 mM sodium chloride solution for 1 h and 3 h, the CmMYB1 expression increased significantly and began to decline after 6 h of salt stress, indicating that it functions in the early response to salt stress. These results provide a theoretical basis for the further study of the biological function of CmMYB1.
