Fig. 5. Uptake of 2,4-DNT and DNTS by control and transgenic
switchgrass plants. (A) 2,4-DNT concentration in 1/2 MS liquid culture
medium with time. The control and transgenic switchgrass plants at E2
stage were exposed to 1/2 MS liquid medium supplied with 20
mg·L-1 2,4-DNT, respectively. The blank was 1/2 MS
liquid medium supplied with 20 mg·L-1 2,4-DNT without
plants. (B) DNTS concentration in liquid culture medium with time. The
control and transgenic switchgrass plants at E2 stage were exposed to
1/2 MS liquid medium supplied with 1000 mg·L-1 DNTS,
respectively. The blank was 1/2 MS liquid medium supplied with 1000
mg·L-1 DNTS without plants
