Fig. 2: Expression patterns of different expressed transcription factors (DETFs) were shown in two cultivars.
From: Papaya CpbHLH1/2 regulate carotenoid biosynthesis-related genes during papaya fruit ripening

a Expression pattern of 27 DETFs from green (GRN), color break (CB) to ripeness in AU9 cultivars; b Expression pattern of 23 DETFs from stage 1 (S1) to stage 6 (S6) in SunUp cultivars. The cage of red to blue represents quite different expression level. The highly expressed transcription factors were selected for further analysis. Expression value presented as log2FPKM
