The aitr mutants are tolerant to salt 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 then subjected to salt treatment by watering every other day with 150 mM NaCl for 10 times. Pictures were taken before treatment (up panel), and 1 day after the last salt watering (low panel). The experiments were repeated three times, and similar results were obtained
