Expression of drought-responsive genes in the wild-type and engineered Arabidopsis plants in response to drought treatment. Relative expression levels of RD29A, RD29B and DREB2A. Total RNA was isolated from rosettes grown with water withholding for 9 days and subjected to quantitative reverse transcription-polymerase chain reaction (qRT-PCR) analysis. Values show average ± SD (n = 3). Asterisks indicate significant differences from the wild type (t test, *P < 0.05; **P < 0.01)
