The hps1 mutant is hypersensitive to a decreased level of macronutrients. Five-day-old seedlings of the WT and hps1 mutant grown on glucose-containing MS medium were transferred to sucrose-containing MS medium with different strength of macronutrients. After transfer, the seedlings were grown for another 10 days. (A) Photographs of the WT and hps1 seedlings after growth on the MS medium with different nutrient strength. (B and C): Shoot and root fresh weight (FW) of the WT and hps1 seedlings shown in (A). Data represents means ± SE (n > 10). Values with different letters differ significantly (p < 0.01). Bar = 10 mm.
