Changes in gene transcription.

<p>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 (<i>APXc</i>), membrane-bound ascorbate peroxidase (<i>APXm</i>), and stromatic ascorbate peroxidase (<i>APXt+s</i>), peroxidase (<i>PX4</i>), and violaxanthin de-epoxidase (<i>VDE2</i>).
