Fig. 2From: Genome-wide identification of ubiquitin proteasome subunits as superior reference genes for transcript normalization during receptacle development in strawberry cultivarsStages of strawberry fruit development. The receptacle samples were collected at eight visual developmental stages from strawberry ‘Ruegen’ (diploid) (Bar = 1 cm) (a) or ‘Monterey’ (octaploid) (Bar = 2 cm) (b).
