Fig. 3From: A subtracted cDNA library identifies genes up-regulated during PHOT1-mediated early step of de-etiolation in tomato (Solanum lycopersicum L.)Analysis by quantitative real-time PCR of expression of selected genes belonging to different functional categories. The data represent the average fold change of 3 independent biological replicates ± SEM. Normalization was done using the pp2ase gene as housekeeping gene. Fold change was calculated compared to the value obtained for the dark control sample. The non-parametric Mann-Whitney U test (Statistica 12) was used to determine the significance of the resultsBack to article page
