AFP1 — Camelina sativa

Summary

CSA16G023280 (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 is linked to pathogen resistance, including resistance to Rhizoctonia solani, Fusarium graminearum, Alternaria brassicicola, and Botrytis cinerea, and to aphid and herbivore resistance. The encoded protein is localised to secretory vesicles and the extracellular space. Associations with salt tolerance, UV-C response, and induced systemic resistance have also been noted. Studies of related genes in other species further connect the gene to fungal disease resistance, insect resistance, and systemic resistance.
