Ethylene Response Factor Sl-ERF.B.3 Is Responsive to Abiotic Stresses and Mediates Salt and Cold Stress Response Regulation in Tomato
Figure 5
Cold stress effect on wild type and Sl-ERF.B.3 antisense lines. (a) Photographs of both Sl-ERF.B.3 antisense transgenic tomato lines (AS25) and wild type (WT) were taken after 14 days of cold treatment (2°C) then three days of recovery (25°C). Control: plants were grown under normal growth conditions. (b) Electrolyte leakage means are assessed in two Sl-ERF.B.3 antisense transgenic tomato lines (AS25 and AS38) and in wild type (WT) treated or nontreated by incubation at 2°C temperature during 14 days. (c) Percentages of relative increase in electrolyte leakage between control (maintained at 25°C) and cold stressed (incubated at 2°C) plants of both wild type (WT) and Sl-ERF.B.3 antisense transgenic lines (AS25 and AS38). Data are means of three replicates ± standard error. Same letters and different letters indicate, respectively, nonsignificant differences and significant differences between data, according to Student’s -test.
