EDM1 — Nicotiana attenuata

Summary

A4A49_33738 (EDM1, SGT1) on chromosome 4 of coyote tobacco encodes a protein with Sgt1-like, TPR, CS and SGS domains and HSP20-like chaperone features, annotated with Hsp90 binding, ubiquitin ligase binding, SUMO transferase activity, and chaperone protein binding. The gene is associated with defense responses, including respiratory burst, hypersensitive cell death, and effector-triggered immunity, as well as responses to phenylalanine, humidity, cold, and auxin. It is linked to traits such as disease tolerance, insect damage response, photosynthetic rate, stomatal opening, flowering time, cadmium concentration, and temperature stress response. Localization evidence connects it to the nuclear matrix, SCF complex, stress granules, and vacuole. Related genes in other species link the family to basal defense, disease resistance, and heat tolerance.
