Changes in gene transcription.

Real-time-qPCR expression values (n fold) relative to the expression value observed under control conditions of temperature (25/20°C) and water availability (WW), within each genotype. The values are for the entire experiment from leaves of Apoatã, Icatu, and Obatã genotypes, under well-watered (WW), mild drought (MD) and severe drought (SD) conditions, and submitted to temperature control conditions (25/20 oC), at the end of the acclimation period (13/8 oC), after 3 chilling cycles (3x13/4 oC), after 7 days under rewarming conditions (7x Rec Cold), and after a further 7 days period under rewatering conditions (7x Rec Drought). It were studied genes of the enzymes ascorbate peroxidases from cytosolic ascorbate peroxidase (APXc), membrane-bound ascorbate peroxidase (APXm), and stromatic ascorbate peroxidase (APXt+s), peroxidase (PX4), and violaxanthin de-epoxidase (VDE2).
