Research looks at growth and development in the model plant Arabidopsis thaliana, which is easy to grow, has a short life cycle, has a small genome, and produces thousands of seeds per plant. By making genetic mutants of Arabidopsis we are able to select for mutant plants in which processes that are known to be controlled by gibberellins are altered. An investigation into which biochemical processes have been altered or perturbed in a mutant can lead to a clearer understanding of how those processes operate in wild-type individuals.

Sub-cellular signaling pathways have been identified to track key players such as the stress activated protein kinases (SAPK), viability markers such as P38 and differentiation gene transcription factor RUNX2. By following pathways from outside the cell, through internal protein signaling and finally to the production of specific proteins by the cell, we can help explain the mechanisms responsible for implant rejection or successful long-term integration.
