FIGURE 2.

Growth and TAG content of Arabidopsis thaliana cell cultures incubated 72 h in the presence of taxol, 5-fluorouracile (5-FU), MTX, MTX+Met or grown in a nitrogen-deficient medium. (A) Fresh weight after 72 h of treatments. The initial cell concentrations at t = 0 h were 0.3 g per 10 mL of culture in each conditions. (B) TAG content expressed as μg of fatty acid (FA) per mg of fresh weight. All the measurements were made after 72 h of treatment. The data are means ± SD of five (MTX and MTX+Met) or three (Taxol, 5-FU, and –N) independent biological repeats.
