Plants
immunity research and dates back many decades. Plants donot have an adptive immune system-
antibodies and
T cell responses in higher mammals- but they have an innate defense mechanism which could also be inducible.
Like
animals, plants can recognize PAMPs (
pathogen associated molecular pattern) using PRRs (pattern recognition receptors). plant PRRs are similar to
Toll like receptors in having a LRR (leu rich repeat) and TIR (toll Interleukin-1) domains. Plants also produce antimicrobial factors,
pathogenesis related (PR)
proteins being one of the well studied ones.
