AFP3 — Brassica juncea

Summary

BJUB06G16200S (AFP3, also known as BjPR12, PDF1.1, LCR67, or PR12) in Indian mustard (Brassica juncea) on chromosome B06 encodes a plant defensin family protein, characterized by a Defensin_plant domain and knottin fold. The gene is associated with defense responses, including against Gram-positive and Gram-negative bacteria, fungi, and systemic acquired resistance, as well as killing of cells of other organisms. Its product is localized to the extracellular space. The gene is linked to stress response phenotypes. Studies of the Arabidopsis relative PDF1.1 connect the defensin family to resistance against Cercospora beticola and bacterial pathogens. Additionally, sequence similarity links related genes in other species to transpiration rate and salt response traits.
