DELT1 — Brassica napus

Summary

BnDELT1 (also known as BnRBOHD) on chromosome A06 of oilseed rape encodes a protein with NAD(P)H oxidase H2O2-forming activity, transmembrane receptor protein tyrosine kinase activity, and calcium ion binding, and contains EF-hand domains. The gene is associated with immune response-regulating signaling pathways, detection of bacteria, metabolic burst, reactive oxygen species (ROS) metabolic process, and PTI signalling. It is linked to chlorophyll breakdown, regulation of leaf senescence, and carbohydrate homeostasis. Agronomically, BnDELT1 is associated with grain yield trait, bacterial blight disease resistance, drought tolerance, salt stress tolerance, aphid response trait, aluminum response trait, root hair length, stomatal closure, flowering time trait, and seed growth and development trait. Studies of related genes in other species link the family to systemic signaling, apoplastic oxidative burst, and defence response.
