AFP — Phaseolus vulgaris

Summary

PHAVU_005G071300, designated AFP or PvAFP, encodes a plant defensin belonging to the Defensin_plant family, characterised by a knottin fold and scorpion-toxin-like superfamily domain. 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 encoded protein localises to the extracellular space. The gene has also been linked to amino acid content. Studies of related genes in other species connect the family to drought tolerance, water use efficiency, transpiration rate, stomatal resistance, root volume, root length, plant height, germination rate, proline content, and protein content.
