Heat-repressed unigenes in cold treated peach fruit.

<p>The relative-to-harvest (H) level of accumulation of 9 selected heat-repressed transcripts was determined in the peach fruit subjected to 3 (R3) or 5 days at 0°C (R5) followed by 2 days at 20°C (R5+2). Gene expression levels were normalized against <i>Arabidopsis thaliana rad50</i> (gb|AF168748.1|AF168748). Bars with at least one equal letter mean no statistically significant difference (α = 0.05). Cold-repressed transcripts are grouped in red and cold-induced transcripts in green. The transcript that was not modified by the cold treatment (R14) is in grey; while transcript R2, which resulted induced in R5 but repressed in R5+2, is in yellow.
