Fig. 7.

Patterns of gene expression of actin (AC), HcBGAL1 (BG), HcXTH1 (XTH), HcAlkIN1 (AlkN), and HcSUS1 (SUS) in different organs of 45-d-old seedlings of H. courbaril. Gene expression was followed using semi-quantitative RT-PCR during 24 h by sampling every 6 h. White solid bars represent the dark periods and dashed lines the light periods during the experiment. After germination, developing seedlings were kept under continuous light or darkness for 20 d. Densitometry was performed for each gel and essentially confirmed the patterns observed in this figure.
