Figure 6From: Arabidopsis WRKY2 transcription factor mediates seed germination and postgermination arrest of development by abscisic acidRNA levels of ABI5 , ABI3 , Em1 and Em6 in wrky2 mutants and wild type. RNA was extracted from seedlings on MS medium without ABA or with 1.5 μM ABA 4 d or 7 d after the end of stratification. Relative RNA levels of 4 genes were analyzed using gene-specific primers by real-time PCR. Three independent experiments are shown by reextracting RNA from other samples. Each experiment also was executed three times.Back to article page
