Gene expression study after 1 and 3 days of salt exposure in a Solanum tuberosum cultivar called PS3

ABSTRACT: The molecular response to salt exposure was studied in the leaves of a S. tuberosum clone using cDNA microarray. Differentially expressed genes were classified according to their known or predicted function and their expression ratio as compared to the control. The major changes upon a 150 mM NaCl exposure in potato leaves occurred in the photosystem apparatus and Calvin cycle: many transcripts coding for proteins belonging to photosystems I and II and chlorophyll synthesis were repressed. On the other hand, we observed the induction of various kinds of transcription factors implicated in osmotic stress response via ABA-dependent or ABA-independent pathways but also in plant defense pathways. This revealed a crosstalk between abiotic and biotic stress responses during salt exposure, which
