Additional file 1: Table S1. of Interaction of plant growth regulators and reactive oxygen species to regulate petal senescence in wallflowers (Erysimum linifolium)

Primers used for RT-PCR. Figure S1. Ethylene production by whole isolated flowers at four developmental stages: stages in wallflower senescence: Stage 1 – fully open pale flowers; 4/6 anthers protruding; Stage 3 – petals held more loosely, beginning to wilt, darker; Stage 4 – petals limp and curled over, darker colour, wilting clearly evident; Stage 5 – clear petal deterioration; Figure S2. Effect of different NAA concentrations on progression of petal senescence in detached flowers. Flowers were detached at Stage 1 and treated continuously for 4 days. Figure S3. Effect of different CEPA concentrations on progression of petal senescence in detached flowers. (PPTX 356 kb)
