Flagship Project 2: Crop Sciences - Water Use and Photosynthesis

a) Improving Water Use and Yield Stability in Pearl Millet and Sorghum

In this part of the project, we aim to identify crops that use water more efficiently without compromising productivity. For every kilogram accumulated, crops can lose around one tonne of water. This is because for plants to grow they must lose water through pores in the leaf. Some crop varieties show more dynamic opening and closing of these pores in response to changing conditions, and thus lose less water per unit growth. Some crops show increased rates of photosynthesis for the same rate of water loss. Our aim is to use germplasm relevant to agriculture in India to identify crop accessions that save water.

b) Enhancing Photosynthesis

The aim is to enhance photosynthesis by identifying components of the algal Carbon Concentrating Mechanism (CCM) for expression in higher plants.
