I really enjoyed reading this review. Look at all the useful stuff that disordered regions of proteins can do - from stress signaling to molecular recognition.
"The plant protein families discussed above show that plant IDPs
possess crucial cellular functions to respond to changing
physiological conditions. The binding promiscuity and plasticity
of plant IDPs confer upon them a unique predisposition to play
critical roles in plant protein interaction networks and many, if
not most, biological processes."
