Screening PYL transgenic lines for resistance to drought stress in Arabidopsis. (A) Drought-resistance screening of PYL transgenic Arabidopsis. Fourteen Arabidopsis PYLs and five promoters were used to generate 65 transgenic plants with different promoter-PYL combinations. Two-week-old plants were subjected to drought stress by withholding water for 20 d. Survival rates were calculated at 2 d after rehydration. –, No transgenic plants were obtained. (B and C) pRD29A::PYL9 transgenic plants exhibit improved drought-stress resistance with ABA treatment. Plants were subjected to drought stress after flowering. After water was withheld for 12 d, plants were treated once with 10 µM ABA. (B) Images of representative seedlings. (C) Soil water content during the drought-stress period. Error bars indicate SEM (n ≥ 4).
