We selected the promoter of the ribosomal protein L18a, a protein involved in virus infections (Li et al., 2018), the promoter of vironine synthase an acetyltransferase participating in alkaloid biosynthesis (Pfitzner et al., 1986), the promoter of vacuolar protein sorting - associated protein 1 a protein influencing the multivesicular bodies (MVB) pathway (Williams and Urbé, 2007) and finally the promoter of glucan endo 1-3 beta – glucosidase, an enzyme stimulated upon fungal, bacterial and pathogens infections (Kebede and Kebede, 2021). The gene discussed is RPL18A; the disease is viral infectious disease.
