AFP1 — Camelina sativa

Summary

CSA05G073660, also known as AFP1, CsLCR77, and several PDF1.2 synonyms, encodes a plant defensin family protein containing a knottin domain and 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 specific resistance to Rhizoctonia solani, Fusarium graminearum, Alternaria brassicicola, and Botrytis cinerea, along with 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 additional traits such as sugar, proline, starch, carotenoid, and protein content, as well as transpiration rate, stomatal resistance, and root length.
