Genes Controlling Plant Size

Bigger plants are better, right?  Not always. Control of plant or tree size can have many advantages, and genetic control of 'dwarf' phenotypes has been important in feeding a billion people. The problem is that the changes induced by dwarfing genes can have a negative effect on other aspects of plant biology, so identifying new genes to control size is an important goal.  Dr. Philippa Borrill is a group leader at the John Innes Center, and she recently discovered a gene that contributes to size control in wheat. The discovery establishes a new means to possibly develop more productive crop varieties.
