Tracey is currently working with natural germplasm variants and induced mutants to investigate genes which affect seed composition and seed quality traits in pea.
Thier aim is to improve the protein quality in pea seeds for human and animal nutrition.
Protein variants have been identified from screening the germplasm collection and induced mutant populations.
As well as examining the changes in protein profile they will be assessing the effect of altering seed composition on plant growth, yield and plant/insect interactions.
