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. Most...

CBF1 Drought Gene expression profiles High light Low temperature Potato Transgenic 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. Most transcriptional changes were specific to each condition, but genes involved in phenyl-propanoid biosynthesis were affected by all abiotic stresses evaluated.
