The response to abiotic stress results in a dramatic change of the whole plant transcriptome. This regulation takes place mostly at thetranscriptional level for which the role of transcription factors turns out to be essential. Here we compile the knowledge acquired aboutthe participation of HD-Zip I and II transcription factors in the response to abiotic stress, such as water deficit, low temperature, osmoticstress and different illumination conditions. We finally analyze the effect of transgenic model plants that over express some of the HD-Zipmembers and infer their potential use as biotechnological tools for the obtaining of tolerant transgenic crops.
