Silicon (Si) supplementation permits plants to better deter infection. Supplementing hydroponically-propagated with 1 mM potassium silicate (KSiO) reduced necrotic lesion development on detached leaves by both and . Previously, a family of Si-induced genes was identified in .

MerR family proteins are activator/repressor switches that regulate the expression of bacterial metal resistance genes and have been used in metal biosensors. Upon metal binding, a conformational change switches gene expression from off to on.
