Gene expression of chlorophyll degradation pathway in <i>A</i>. <i>chinensis</i> var. <i>chinensis</i> ‘Hongyang’ outer pericarp during fruit development.

<p><i>CBR1</i>, chlorophyll <i>b</i> reductase; <i>PAO1</i>, pheophorbide <i>a</i> oxygenase 1; <i>PAO2</i>, pheophorbide <i>a</i> oxygenase 2; <i>PPH1</i>, pheophytin pheophorbide hydrolase 1; <i>PPH2</i>, pheophytin pheophorbide hydrolase 2; <i>PPH3</i>, pheophytin pheophorbide hydrolase 3; <i>SGR1</i>, stay-green 1; <i>CLH1</i>, chlorophyllase 1; <i>CLH2</i>, chlorophyllase 2. Error bars indicate standard error (n = 3). The asterisk (*) represents that the sample was used as reference in relative comparison. The different small letters for number in a same gene represent significant difference at 0.05 level. Heatmap were performed using the software of MEV. Color scale represents log2^{−ΔΔ<i>C</i>t} counts where blue indicates low level and red indicate high level.
