Anomalous secondary growth

Several dicotyledons show secondary growth that is different from normal  secondary growth. The deviating methods of secondary thickening are called  abnormal or anomalous secondary growth. 

e.g., Bougainvillea (Dicot)

In the dark, the maximum absorption of the FMN chromophore is around 450 nm. 

Blue light induces the formation of a covalent bond between FMN and a cysteine residue, shifting the absorption maximum to 390 nm via a LOV660 intermediate form. The reaction is reversible in darkness.
