IsiA protects cyanobacterial cells against iron stress.
Quoted textsource-backed
This protein protects cyanobacterial cells against iron stress.
Under iron starvation, blue light-induced nonphotochemical quenching in cyanobacteria involves the phycobilisome OCP-related energy dissipation mechanism and not IsiA.

IsiA initially protects iron-starved cyanobacterial cells by increasing the size of the photosystem I antenna.
Quoted textsource-backed
IsiA, however, does seem to protect the cells from the stress generated by iron starvation, initially by increasing the size of the photosystem I antenna.
IsiA subsequently converts excess energy absorbed by phycobilisomes into heat through a mechanism different from dynamic and reversible light-induced NPQ processes.
Quoted textsource-backed
Subsequently, the IsiA converts the excess energy absorbed by the phycobilisomes into heat through a mechanism different from the dynamic and reversible light-induced NPQ processes.
In iron-starved cyanobacterial cells, absence of IsiA does not affect induction or recovery of blue light-induced fluorescence quenching.
