Diversity in Pisum seeds
Claire Domoney, Catherine Chinoy, Mike Ambrose, Andrew Davis
The composition of plant seeds is extremely important in supplying appropriate nutrition to human and animal diets. There is a wealth of unexplored variation within diverse germplasm, which can be exploited in the removal of anti-nutrients and in promoting the value of plant foods for human health. In this image (provided by the Domoney laboratory at the John Innes Centre on the Norwich Research Park) we see a sample of seed phenotypic trait variation within Pisum (pea), including wild relatives of cultivars. Variation in seed size, shape, testa and cotyledon colour is apparent, which is related to changes in seed composition, end-use and nutritional value.
