Rice Lines

Caption: Photos of two rice lines that are genetically identical except for the genes that control tolerance to submergence. Left panel: Two-week-old rice seedlings prior to submergence stress. Right panel: Four-week-old seedlings immediately after two-weeks of complete submergence. Pots labeled "T" contain the submergence tolerant line. These plants have suppressed growth and conserved carbohydrate fuel. They regrow and produce seed. Pots labeled "I" contain the submergence intolerant line. These plants have grown during the stress and exhausted their energy reserves. They do not recover from the stress.
