Associate Prof. Sigal Savaldi-Goldstein



Main energy field:

The molecular underpinning of plant growth control in response to adverse environmental conditions. Our basic research is expected to open new avenues toward potential biotechnological means of improving plant performance and solutions for the worldwide agricultural production and food sustainability.
