CXE17 — Nicotiana attenuata

Summary

A4A49_16899 (symbol CXE17, also known as NaHSR203J or HSR203J) on chromosome 2 of coyote tobacco (Nicotiana attenuata) encodes a protein with carboxylesterase, 2-hydroxyisoflavanone dehydratase, isomerase, lyase, and hydrolase activities, belonging to the alpha/beta hydrolase and carboxylest/Gibb_receptor domain families. The gene is associated with defense response, programmed cell death, hypersensitivity, systemic acquired resistance, immune response, MAPK cascade, metabolic burst, salicylic acid anabolism, isoflavonoid and flavonoid anabolism, alkaloid metabolism, virus-induced PTGS, signal transduction, nucleoside anabolism, and sporulation. It is linked to leaf necrosis and bacterial disease response. The protein localizes to the amyloplast, cytosol, and nucleus. Related genes in other species are linked to disease resistance.
