The pGreenII 62-SK is a plant expression vector or a type of plasmid used in genetic engineering for plant organisms. This high copy number vector can contain large fragments of foreign DNA, making it a prevalent tool in the field of gene cloning and gene function studies.
The vector measures 3347 base pairs, utilizing a Cauliflower mosaic virus (CMV) promoter to initiate the transcription process. The pGreenII 62-SK vector's resistance marker is kanamycin and puromycin serves as its selection marker. This is beneficial for researchers as it allows them to differentiate cells that have been transformed with this plasmid from those that haven't. Additionally, the pGreenII 62-SK vector is compatible with standard cell lines, including 293, CV-1 and CHO. Furthermore, pGreenII 62-SK possesses a constitutive expressional nature, implying that the gene of interest under the control of the promoter is continuously expressed without the requirement of particular stimuli.
Jasmonate (JA) is an important hormone that plays a role in plant defense. The cam1 and wrky53 mutants were more resistant to Spodoptera litura than the wild-type (WT) Arabidopsis group. Furthermore, the JA concentration was higher in cam1 and wrky53 mutants compared with the WT group. To explore how these two proteins influence resistance in Arabidopsis plants, the researchers used a yeast two-hybrid assay, firefly luciferase complementation imaging assay and in vitro pull-down assay confirming that calmodulin 1 (CAM1) interacted with WRKY53. This study shows that CAM1 and WRKY53 regulate the JA biosynthetic pathway through CAM1-WRKY53 dissociation, thereby negatively regulating plant resistance to herbivory, and then the released WRKY53 binds to the LOXs promoter and negatively regulates LOXs gene expression. This study reveals the insect-resistant mechanism of WRKY53 and provides new clues to the function of WRKY53.
In luciferase activity assays, WRKY53 pGreenII 62-SK interacted with the LOX3 promoter pGreenII 0800-LUC, and WRKY53 pGreenII 62-SK negatively regulated LOX3 pGreenII 0800-LUC expression. However, when CAM1 pGreenII 62-SK was added to the system, LOX3 pGreenII 0800-LUC expression returned to control levels.
