Does the bending causes by the accumulation of auxin at the root tip and shoot tip remains evergreen. i.e., the plant will not be straight again at the night( in absence of sunlight) ??

or
the process is reversible whenever there is sunlight the auxin accumulates, performs its work and went off, in absence of sunglight the plant is able to come back to original shape or structre.?

Pls clear my doubt, I hope I am able to present the query in an understandable manner..!!

Thank you
