Fig. 6From: Identification and functional analysis of cation-efflux transporter 1 from Brassica juncea L.Heavy metal tolerance of BjCET1 transgenic tobacco leaves. The healthy transgenic tobacco leaves were selected as control. The round blades were placed in ddH2O, 200 μM NiCl2, 400 μM ZnCl2, or 200 μM CdCl2. Ten independent pieces were placed in each Petri dish. The status of the leaves was observed after 5 daysBack to article page
