He is an author of more than papers. My research interests include determining the regulatory networks that control abiotic stress tolerance mechanisms in plants, particularly drought, desiccation and nutrient deficiency. My research group is also interested in developing novel tissue culture-independent plant transformation methods, as well as designing strategies to integrate epigenetic changes in plant breeding.

Using the natural gene transfer system of the soil bacterium, Agrobacterium tumefaciens, we were able to generate a reproducible system to introduce genes into plants cells that could be regenerated into mature plants.

Using this system, we were able to identify DNA regulatory elements that allow plants to turn on genes in response to light stimuli and the protein sequence present in many of the corresponding gene products that allow their entry into the chloroplast, where they participate in the process of photosynthesis. More recently, my laboratory has shown that the release of organic acids into the soil plays an important role in making plants capable of utilizing insoluble nutrient forms.

We are currently investigating the molecular mechanisms that allow plants to sense nutrient availability and the genes involved in changing the architecture of the root system to allow plants the exploration of novel soil domains to facilitate nutrient acquisition. Developmental Cell 5 41 Malate-dependent Fe accumulation is a critical checkpoint in the root developmental response to low phosphate.
