Fig. 1: Differentially expressed genes (DEGs) between ‘Concord’ and V. vinifera at veraison and ripening stages.

a DEGs with more than 5-fold higher (orange, n = 35) or lower (blue, n = 58) expression in ‘Concord’ than in four V. vinifera cultivars at both veraison and ripening stages (TPM >= 50). Expression profiles of AMAT-1 (Vitvi09g01895) (b), AAMT1-14 (Vitvi04g02122) (c), and one polygalacturonase (PG) gene (Vitvi08g02394) (d) at three berry developmental stages in ‘Concord’ and four V. vinifera cultivars
