Nottingham scientists reveal genetic 'wiring' of seeds
Date:5/18/2011

adian government to work with Professor Mike Holdsworth on research into seed germination. He has since been awarded a prestigious Marie Curie International Incoming Fellowship.

Dr Bassel said: "To our surprise, the seed network demonstrated that genetic factors controlling seed germination were the same as those controlling the other irreversible decision in the life cycle of plants: the decision to start flowering. The induction of flowering, like germination, is highly responsive to cues from the environment."

Another key finding from SeedNet was that the same genes that leaves and roots use to respond to stress are used by seeds to stop their germination. Given that seeds were evolved long after plants developed their ability to withstand environmental stress, this indicated that plants have adapted existed genes to fulfil a different role. The work could lead to identifying important factors controlling stress response in seeds and the plant itself, contributing towards the development of new crops producing increased yields under extreme environmental conditions such as drought or floods.
