Photosynthesis is important for plant fitness. By producing sugar from light, water and carbon dioxide, photosynthesis provides the plant with energy to grow, produce seeds and survive. When photosynthesis is curtailed, plants remobilise stored resources which may become depleted. When growth is limited, reduced sink strength may feedback on photosynthesis. This dynamic relationship between photosynthesis, growth and sugar production is integral component of plant function. My thesis will focus on two sugar sensors in plants: Target of Rapamycin (TOR), Hexokinase (HXK). I will investigate how these sensors differentially regulate growth and photosynthesis of model C3 and C4 plants.
