Abstract
IT has been known for more than 10 years that there are two light-induced electron paramagnetic resonance (EPR) signals in plants. A recent review has summarized what is known about them1. My purpose here is to characterize in a preliminary way a hitherto unreported light-induced EPR signal in Anacystis nidulans, which I name signal III. This signal can readily be distinguished from the other two signals. I do not know why nobody has detected it before, but it is real, and its source is being investigated.
