AtCBF1 Overexpression Confers Tolerance to High Light Conditions at Warm Temperatures in Potato Plants

We characterized transcriptional responses of potato plants to multiple abiotic stresses and used this information to identify potential mechanisms through which over-expression of the stress related transcription factor CBF1 from Arabidopsis thaliana (AtCBF1) confers multiple stress tolerance.
