Nucleoside Triphosphates Rescue Arabidopsis Cells from FB1-Induced Death.

(A) Light-grown cell cultures adjusted to a density of 5% (w/v) were treated with either 0.014% methanol (control) or 1 μM FB1 mixed with 1 mM of the indicated compounds. Cells were harvested 120 h later, and viability was determined via the MTT assay.

(B) Cell cultures were treated with water (control), 1 mM AMP, or 1 mM UTP and ATP in the growth medium assayed by the luciferin–luciferase method. Data and error bars represent means ± sd (n = 3).
