SUB1A plants exposed to complete
darkness for up to 18 d and recovered
under regular growth conditions for
14 d. B, Viability of plants treated with
18 d of complete darkness. The survival
of each genotype was evaluated
14 d after recovery. Plants were counted
as viable if new leaves appeared during
recovery. The data represent means 6
SD from three biological replicates (n =
75). Asterisks indicate significant differences
between the two genotypes (P
