Ethylene Response Factor Sl-ERF.B.3 Is Responsive to Abiotic Stresses and Mediates Salt and Cold Stress Response Regulation in Tomato
Figure 3
Salt stress effect on root to shoot ratio of Sl-ERF.B.3 antisense transgenic lines (AS25 and AS38) and wild type (WT) tomato plants. (a) Photograph, taken at sampling time after six weeks of salt stress (regular irrigation by 200 mM NaCl solution), shows growth differences between wild type (WT) and Sl-ERF.B.3-antisense transgenic line (AS38). (b) Variation of root to shoot ratio mean under salt treatment (200 mM NaCl). (c) Relative increase rate of root to shoot ratio in response to sever salt stress treatment in wild type (WT) and Sl-ERF.B.3 antisense transgenic lines (AS25 and AS38). Pairwise comparisons were made between wild type plants and antisense transgenic plants with Student’s -test (a: , b: ). Data represent means and standard error of three replications.
