AFP — Phaseolus vulgaris

Summary

PHAVU_005G071400, symbol AFP and also known as PvAFP or PvDEFENSIN, encodes a plant defensin protein belonging to the Defensin_plant family, characterized by knottin and scorpion-toxin-like superfamily domains. In French bean (Phaseolus vulgaris) on chromosome 5, this gene is associated with defence response to fungi, killing of cells of other organisms, hyphal growth, sphingolipid anabolism, sulfate assimilation, sulfur metabolism, and NO storage. The product is localized extracellularly. The gene is also linked to amino acid content. Studies of related genes in other species connect this family to drought tolerance, water use efficiency, transpiration rate, stomatal resistance, root volume, root length, plant height, germination rate, proline content, and protein content, though these traits are not yet established for the French bean gene itself.
