Antimicrobial peptides generally are cysteine-rich, cationic, and amphipathic. 

Because of their positive charge and amphipathic nature, they interact with acidic phospholipids in lipid bilayers, forming pores and disrupting the membranes of bacteria, fungi, parasites, and viruses.

In the bacterial genome, the minimum length of promoter that could provide an adequate signal is 12 bp.  The minimum length required for unique recognition increases with the size of genome, a problem in eukaryotic genomes.

A brief pulse of red light will induce a response, provided that the light is sufficiently bright, and conversely, very dim light will work if the irradiation time is long enough. 

This reciprocal relationship between fluence rate and time is known as the law of reciprocity
