From: Tomato SR/CAMTA transcription factors SlSR1 and SlSR3L negatively regulate disease resistance response and SlSR1L positively modulates drought stress tolerance

Figure 8

Silencing of SlSR1L led to reduced drought stress tolerance. Two-week-old tomato seedlings were infiltrated with agrobacteria carrying pTRV2-SlSR1L or pTRV2-GUS constructs and 3 weeks later the pTRV2-GUS- and pTRV2-SlSR1L-infiltrated plants were subjected to drought stress by stopping watering. (A) Phenotype of the pTRV2-GUS- and pTRV2-SlSR1L-infiltrated plants before and after treatment of drought stress. (B) Rates of water loss in detached leaves of the pTRV2-GUS- and pTRV2-SlSR1L-infiltrated plants. (C) Root system of the pTRV2-GUS- and pTRV2-SlSR1L-infiltrated plants. The intact root systems are shown from one representative pTRV2-GUS- or pTRV2-SlSR1L-infiltrated plant. (D) Dry weights of roots from the pTRV2-GUS- and pTRV2-SlSR1L-infiltrated plants. (E) Expression of some drought-responsive genes in the pTRV2-GUS- and pTRV2-SlSR1L-infiltrated plants before and after treatment of drought stress. Data presented in (B), (C) and (E) are the means ± SD from three independent experiments and different letters above the columns indicate significant differences at p?<?0.05 level.
