Gene expression of drought response genes. Expression levels of candidate genes for drought response and/or drought tolerance determined by real-time RT-PCR analysis using GADPH as standard gene for normalization in tolerant and sensitive Vicia greenhouse-grown 4-week-old plants under drought or control conditions. Values are the average (± standard deviation) of at least three assays. Asterisks show differences p < 0.05 (Student’s test) referred to control 521 tolerant plants
