AFP1 — Camelina sativa

Summary

CSA05G073650 (AFP1, also known as CsLCR77 and PDF1.2) encodes a plant defensin family protein containing a Knottin domain and a scorpion toxin-like superfamily fold. The gene is associated with defence responses to both Gram-positive and Gram-negative bacteria, fungi, and insects, as well as with jasmonic acid/ethylene-dependent systemic resistance, wax anabolism, and cell killing. It has been linked to pathogen resistance, including against necrotrophic pathogens such as Botrytis cinerea, Fusarium graminearum, and Rhizoctonia solani, as well as to aphid and herbivore resistance, salt tolerance, and UV-C response. The encoded protein is localised to secretory vesicles and the extracellular space. Studies of related genes in other species connect the family to fungal disease resistance, insect resistance, and systemic resistance.
