Defensins are one the largest group of antimicrobial peptides and are part of the innate
defence. Defensins are produced by animals, plants and fungi. In animals and plants,
defensins can be constitutively or differentially expressed both locally or systemically which
confer defence before and a stronger response after infection. Immune signalling pathways
regulate the gene expression of defensins. These pathways include cellular receptors,
which recognise pathogen-associated molecular patterns and are found both in plants and …
