Evaluation of Antifungal Activity of Defensin (Tfgd2) Using Its Heterologous Expression in E. coli
Defensins are a superfamily of antimicrobial peptides that can inhibit the growth of a broad spectrum of fungi. To evaluate the antifungal activity of Tfgd2 gene of Trigonella foenum graecum, the coding region of this gene in the cDNA form was subcloned in the expression vector pET26b (+) and the co...
