An important problem in in biology is to understand how the characteristic final sizes of organs and organisms are set. In the flowering plant Arabidopsis we have identified a set of genes that normally function to set the final sizes of organs such as petals, seen here. The top left flower is a normal Arabidopsis and the others are single, and combinations of, mutants that disrupt the functions of these genes. We are working at the John Innes Centre on the Norwich Research Park to understand how these combinations of mutants function in setting organ size, and to see if similar mutants in crops can increase seed size and yield.
