Survival of Arabidopsis plants to submergence. A, Wild-type plants (Col-0) and pgm mutant plants were submerged for 36 and 72 h. The pictures, taken immediately after the submergence treatment or after recovery (10 d), show the consequences of the submergence treatment. B, Iodine staining of starch of plants that were submerged for 36 and 72 h. C, Sugar content in rosette leaves of Arabidopsis pgm plants that were submerged at the end of the light period. Submergence was carried out in the dark. Sugars were quantified at the end of the day (Time 0) and after 4 and 12 h of darkness/submergence. Data are mean ± sd of five biological replicates, n = 3 for sugars (ANOVA, P < 0.05).
