The aitr mutants are tolerant to drought treatment. Seeds of the Col wild type, the aitr256 triple, aitr1256 quadruple, aitr23456 quintuple and aitr123456 sextuple mutants were germinated directly and grown in soil pots in a growth room with sufficient watering for 30 days. The plants were subjected to drought treatment by withholding watering for 12 days. Watering was then resumed. Pictures were taken before (up panel), and after drought treatment (middle panel), and 2 day after watering was resumed (low panel). The experiments were repeated three times, and similar results were obtained.
