Fig. 4. — SpUSP overexpression enhances drought tolerance in tomato. (A) Drought tolerance tests for SpSUP-overexpressing (OE44, OE54, and OE69) and wild-type ZS6 plants grown in the same pot. The phenotypes under well-watered (‘Control’) and drought-stress conditions (‘Drought’) are shown.. (B) Effects of drought on the fresh and dry weights of the OE and wild-type lines. (C) Chlorophyll contents in plant leaves under drought stress (‘DS’) or normal condition (‘CK’). (D) Proline accumulation in plant leaves under drought stress. (E) Relative expression levels of P5CS1 in the OE and wild-type lines under drought stress via qRT-PCR. (F) Soluble sugar content in plant leaves under drought stress. (G) MDA content in plant leaves under stress (‘Drought’) or normal condition (‘Control’). The data shown are the mean ±SE (n=3). Single (*P <0.05) and double (**P <0.01) asterisks denote statistically significant differences between the transgenic and wild-type lines under drought stress.
