- Abstract:
- Evolution generally proceeds via step-by-step changes in form or structure, this occurring at both an organismal and molecular level. Eventually this process leads to individuals that are ever more diverged from their ancestors. Overtime, and through isolation mechanisms, these differences can become so great that the organisms can be considered as a new species. Thus the tree of life is usually thought to arise through the acquisition of ever more derived characters in a step-wise manner over hundreds (if not thousands) of generations. This view of evolution is severely challenged when we consider speciation in many plant groups (and increasingly it appears in animal groups). This is because different plant species regularly hybridise between themselves, relinking previously separate lineages. This process has many genetic consequences, in particular, it is associated with the duplication of all their chromosomes, a process known as polyploidy. The function of this proposal is to address deficiencies in knowledge relating to interspecific hybridisation and associated polyploidy. Understanding evolution in polyploids is central to a proper appreciation of plant speciation and the generation of biodiversity. It is also necessary if we are to exploit and conserve plant taxa. We will be targeting, in the plant genus Nicotiana, polyploids of widely different ages from recent (made by this team) to ancient (millions of years old). These plants will enable us to determine the long and short term genetic consequences of polyploidy on plant genome structure and evolution.
