Grantee Description
Host institution: University of Cape Town, South Africa.
Area of research: Plant physiology
Research focus: Current research is on the role of transpiration-driven mass-flow on growth and nutrient delivery to roots of C3 and C4 crops, and consequences of changing atmospheric CO2 concentration.
This research evaluates whether the concentration mechanism of C4 (maize) alter nitrate and ammonia uptake relative to C3 (wheat). It also seeks to find out whether nutrient supply can be optimised to account for transpiration differences and hence mass flow differences between C4 and C3 crops. This work also seeks to understand how elevated atmospheric CO2 alters nitrate and ammonia uptake through mass-flow in C4 (maize) relative to C3(wheat).
