2.7.7.13 down expression is inhibited by dark 739330 2.7.7.13 down the expression of isoform VTC1-1 is inhibited by dark 743479 2.7.7.13 down the expression of OsVTC1-1 is inhibited in roots in the dark 739330 2.7.7.13 down the expression of OsVTC1-3 is inhibited in roots in the light 739330 2.7.7.13 down transcript abundance in all the organs of acerola examined, with the fruit having the highest expression. The relative transcript abundance of Malpighia glabra GDP-D-mannose pyrophosphorylase mRNA levels in the fruits changes as the ripening process progresses, with the unripe green fruits having the highest relative mRNA level, and the lowest is found in the fruits at advanced ripening stage 749007 2.7.7.13 up expression is induced by dark 739330 2.7.7.13 up expression is induced by light 739330 2.7.7.13 up expression is induced by the dark 739330 2.7.7.13 up the expression of isoform VTC1-1 is induced by light 743479 2.7.7.13 up the expression of isoform VTC1-3 is quickly induced by dark 743479
