Fig. 3From: A repeat region from the Brassica juncea HMA4 gene BjHMA4R is specifically involved in Cd2+ binding in the cytosol under low heavy metal concentrationsZn and Cd tolerance of BjHMA4-transformed yeast (YK44) cells. YK44 (ura3–52 his3–200, △ZRC, △Cot1, mating type a) lacks the ability to accumulate Zn/Cd in vacuoles, and pYES2-BjHMA4-transformed YK44 grows slightly better than the control in the presence of 200 μM ZnCl2 and 40 μM CdCl2Back to article page
