Comparative gene expression analysis in fruits of a tomato introgression line performing reduced ascorbic acid content

ABSTRACT: Ascorbic acid (AsA), important for plant cell protection against oxidative stresses, is useful for human health. Among vegetables, tomato is the most important specie due to its significant consumption at worldwide level. Although AsA metabolism has been characterized in detail, the genetic mechanisms controlling AsA accumulation in tomatoes are poorly understood. We used an introgression line (IL 10-1) containing a QTL inducing a reduced AsA accumulation in the fruit and carried out a comparative transcriptomic analysis in fruit tissues using a parental cultivar (M82) with normal fruit AsA levels as a reference. We identified 233 differentially expressed genes, indicating that AsA accumulation in IL 10-1 reflects modification in the peroxisomal metabolism and reduced glutathione biosynth
