Seeds are the largest source of human and animal nutrition on the planet, and seed sales are central to the agro-economy. Optimising seed performance is therefore a key goal for the seed industry, growers and food producers. Because seed vigour is highly contingent on the temperature during seed production, climate change is a major confounding factor for future production of resilient high quality seeds.
As seed biologists, we are interested in understanding how environmental sensing in seeds generates seasonal plant behaviour and crop seed performance. My group’s focus is on understanding how environmental information gathered by the mother plant is used to control progeny seed traits and life history, via seed dormancy and germination vigour.
Using this knowledge we are devising and testing strategies to engineer crop seeds to be less sensitive to the seed production environment. Working with industrial partners we are to taking novel germplasm through to field trials to evaluate potential for genetic seed quality improvement.
