Abstract
Apple is characterized by its high adaptation to diverse growing environments.
However, little is still known about how different environments can regulate
at the metabolic or molecular level specific apple quality traits such as the
yellow fruit peel color. In this study, changes in carotenoids and chlorophylls,
antioxidants as well as differences in the transcriptome were investigated by
comparing the peel of “Golden Reinders” apples grown at different valley
and mountain orchards. Mountain environment favored the development
of yellow color, which was not caused by an enhanced accumulation of
carotenoids but rather by a decrease in the chlorophyll content. The yellow
phenotype was also associated to higher expression of genes related to
chloroplast functions and oxidative stress. Time-course analysis over the
last stages of apple development and ripening, in fruit from both locations,
further revealed that the environment differentially modulated isoprenoids
and phenylpropanoid metabolism and pointed out a key role for H2O2 in
triggering apple peel degreening. Overall, the results presented herein provide
new insights into how different environmental conditions regulate pigment
and antioxidant metabolism in apple leading to noticeable differences in the
apple peel color
