A research study is presented in which Arabidopsis thaliana, a model plant
widely used in genetic studies, is employed. The main objective was to obtain
transgenic plants with the genetic construct HEN4p::GFP-HEN4, which consists
of a transcriptional and translational fusion between the GFP gene from the
jellyfish Aequorea victoria and the HEN4 gene from Arabidopsis, whose
expression is controlled by the HEN4 gene promoter (HEN4p). This construct
gives rise to a GFP-HEN4 fusion protein, which is expected to exhibit the same
tissue and intracellular localization as the native HEN4 protein. GFP is a green
fluorescent protein, easily visible with fluorescence microscopes, while HEN4 is
a protein involved in regulating reproductive processes in Arabidopsis.
The construct was generated in pGreenII 0179 vector, using a cloning
technique based on DNA assembly. This method facilitated the hybridization of
overlapping sequences between the inserts and between the inserts and the
vector to form a recombinant circular plasmid that was used to transform
Arabidopsis plants via the floral dipping method. The presence of the construction
in the resulting transgenic plants was confirmed by the selection on hygromycin
and PCR. Additionally, root cells were visualized with a confocal microscope
observing fluorescence mainly in the nucleus.
This study demonstrates the efficiency of the cloning process via DNA
assembly, transformation, and the obtaining of transgenic Arabidopsis plants that
express genes of interest, such as the gene fusion obtained in this work, which
will serve to verify the localization of the fusion protein in the tissues and cells of
the plant and, consequently, the native HEN4 protein.
