Effects of the repression of GIGANTEA gene StGI.04 on the potato leaf transcriptome and the anthocyanin content of tuber skin.

ABSTRACT:

Background

GIGANTEA (GI) is a plant-specific, circadian clock-regulated, nuclear protein with pleiotropic functions found in many plant species. This protein is involved in flowering, circadian clock control, chloroplast biogenesis, carbohydrate metabolism, stress responses, and volatile compound synthesis. In potato (Solanum tuberosum L.), its only role appears to be tuber initiation; however, based on findings in other plant species, we hypothesised that the function of GI in potatoes is not restricted only to tuberisation.

Results

To test this hypothesis, the expression of a GI gene in the commercial potato cultivar 'Désirée' was repressed, and the effects of repression at morphological and transcriptome level were investigated. Previously, two copies of GI genes in potat
