How plant roots know when to branch out

From ScienceDaily:

Root branches only form when in direct contact with soil moisture using an adaptive response termed ‘hydropatterning’. Professor Malcolm Bennett of the University of Nottingham, and Professor Ari Sadanandom from the Department of Biosciences at Durham University, discovered that hydropatterning is controlled by a branching master gene called ARF7. Their teams observed plant roots lacking ARF7 were no longer able to hydropattern. The researchers concluded that when roots are exposed to moisture ARF7 remains active and promotes root branching, but when exposed to air, ARF7 is modified and inactivated, blocking root branching.

Professor Sadanandom explained: “Plants are relatively immobile and therefore their growth and development is very much dependent on their environment. Our research has identified the particular protein which can modify, and even inactivate root branching, therefore limiting plant growth and development.

“This is hugely exciting as it opens up the possibility for us to adapt this protein interaction and potentially develop plants that could continue to branch roots even in challenging conditions such as water scarcity.” – Jane Icke, University of Nottingham More.

We keep discovering more information systems in plants and the amount of time for them to develop has been growing shorter. As the Darwinist becomes more urgent, his explanations grow less likely.

Those are millions of years of natural selection acting on random mutation (Darwinism) that these plants did not turn out to have. If Darwinism seemed unbelievable before, what do you think now?
