Fig. 2

Trichome morphology of peach and nectarine accessions. From top to bottom panels, this figure illustrates phenotypes, genotypes (white bar represents 2 cm), accession names, photographs of mature fruit, X-ray micro-tomography (CT) of fruit surfaces (isometric and front view, white bar represents 50 μm), and scanning electron microscopy (SEM) of fruit surfaces (the minimum unit of the scale are 500 and 50 μm for X100 and X1000, respectively) in four accessions. Peach accessions include the GG allele 'Tainung No.11-XingTao' (TN11), the Gg allele 'Tainung No.7-HongLin' (TN7) and the Nectarine accessions encompass the gg allele 'Sunraycer' (Sr), and the Gg allele 'Maravilha Nectarine Mutant' (MN)
