Prof Alison Smith

Programme Leader (Molecules from Nature)
Metabolic Biology

Alison’s research is on starch and sucrose metabolism in the model plant Arabidopsis and in crops including cereals and potatoes.

Alison investigates the genetic and molecular control of starch degradation in leaves and storage organs, and how this is coordinated with plant growth over the day-night cycle and with germination and sprouting.

Her research also explores how starch granules are formed, and factors that determine the rate and amount of starch accumulation in cereal grains.

  • Starch synthesis and degradation in cereal seeds
  • Control of starch turnover in leaves
  • Relationship between starch turnover and the rate of plant growth

 

The expertise of the Smith lab is in primary metabolism in plants, particularly the metabolism of sucrose and starch. We aim to discover how plant growth and yield in different environments is coordinated with the assimilation and storage of carbon. 

They use biochemical, genetic and molecular biological techniques to study this question in Arabidopsis and in cereals. 

Research is done in close collaboration with colleagues who are experts on wheat genomics (Cristobal Uauy lab), chemical genetics (Rob Field lab) and mathematical modelling (Martin Howard lab).
