Fig. 2From: A dense SNP genetic map constructed using restriction site-associated DNA sequencing enables detection of QTLs controlling apple fruit qualityChanges of acid contents and expressions of candidate genes during fruit development in ‘Jonathan’ and ‘Fuji’. ‘Jonathan’ was chosen as a high acidity apple cultivar, while ‘Fuji’ as a low acidity cultivar. Expressions of three filtered candidate genes for fruit acidity were determined (showed in a-c). Since QTL on LG08 was linked to malic acid, citric acid and total acidity, d-f showed their dynamic changes during different periods of fruit developmentBack to article page
