Real-time RT-PCR analyses of the expression of Arabidopsis genes that are newly induced in DEX:CaXEGIP1 transgenic plants. RNA was extracted from the leaves of 4-week-old transgenic Arabidopsis plants 24 and 48 h after mock or DEX treatment. The relative amount of the gene transcript was normalized against the expression level of the UBQ gene. PR5, Pathogenesis-related gene5 (AT1G75040); BGL2, β-1,3-glucanase2 (AT3G57260); GSR1, Gln synthetase (AT5G37600); GSR2, copper-ion binding/Glu-ammonia ligase (AT1G66200). Asterisks indicate significant differences, as determined by the two-tailed Student’s t test (P < 0.05).
