Transcription profiling of Capsicum fruit ripening process

Pepper fruits at four different developmental stages were collected: early fruit [EF; 1 cm long; 7 days after pollination (dap)], mature green fruit (MG; 6-7 cm length; 20 dap), breaking or turning red fruit (BR; fruit are partially red; 35 dap), and red ripe fruit (RR; fully red; 40 dap). Tomato fruits at corresponding developmental stages were also collected: EF (less than 1cm; 7 dap), MG (40 dap), BR (50 dap), and RR (55 dap). For the monitoring of fruit-specific and fruit ripening-related genes, we did array hybridization by using the leaves as a common reference and each corresponding fruit developmental stage sample.
