How Do Our Forms Develop?

Roots find there way around obstacles, such as our forms, in much the same way that we navigate in the dark. In an as yet unpublished study a group at Norwich University have identified a self reinforcing cycle that facilitates forward march. The tips of the advance roots contain a hormone RHD2 , this creates free radicals that stimulate the uptake of calcium (Ca). Ca in tuen stimulates the activity of RHD2, therefore increased free radicals, increased Ca and so forth. When the root tip incounters an unpassable obstacle, the Ca uptake is halted, thus breaking the cycle. Growth will then start elsewhere until the obstacle is passed. Ah, nature! By creating a form through our interface, the user is selecting where these obstacles will be and therefore how the root mass will form.
