Effect on Soil Properties of BcWRKY1 Transgenic Maize with Enhanced Salinity Tolerance

Figure 4

Effects of NaCl stress on the SOD, POD, Pro, MDA, REC, and chlorophyll contents of WT maize and WL-73 transgenic maize plants. WT and WL-73 were treated with 0.5x Hoagland’s nutrient solution and either 0 mM NaCl (control) or 300 mM NaCl for 7 days; then, the SOD, POD, Pro, MDA, REC, and chlorophyll contents were measured. (a) SOD content; (b) POD content; (c) Pro content; (d) MDA content; (e) REC; (f) chlorophyll content. WT, wild-type maize LH1037; WL-73, LH1037 plant transformed with BcWRKY1. indicates a significant difference at 0.01 according to the LSD test (). The standard error is based on the average of three biological replicates. Note: the SOD, POD, Pro, MDA, and REC of WL-73 were significantly lower than those of WT (), while the chlorophyll content of WL-73 was higher than that of WT under 300 mM NaCl treatment for 7 days.
