Expression analysis of VcARF genes during fruit development. A Transcript profiling of VcARFs during fruit development. The transcriptome data from different developmental stages (pad, cup, mg, pink, ripe) were extracted from the previous study reported by Gupta et al. [45]. The color scale beside the heat map indicates gene expression levels, low transcript abundance indicated by blue color and high transcript abundance indicated by red color. B Photograph of fruits at five developmental stages [green pad (GPS), green cup II (GCS), light green/white (FWS), pink (FPS) and blue (FMS) fruits], the scale bar indicates 1 cm. C-E Expression patterns of VcARFs during fruit development. Total RNAs were extracted from fruit of the cultivar ‘Northland’ (V. corymbosum) at the five above-mentioned developmental stages. Data were normalized against VcACTIN, and the expression level at GPS stage was set as 1. Error bars indicate SE of three biological and technical replicates, and different letters indicate significant difference (P < 0.05)
