NIM1 — Solanum lycopersicum

Summary

SlNIM1 (SOLYC07G040690.3) on tomato chromosome 7 encodes a protein with oxidoreductase activity acting on a sulfur group of donors, salicylic acid binding, calmodulin binding, and DNA-binding transcription factor activity. It belongs to the NPR1/NIM1-like family, containing BTB/POZ domains. SlNIM1 is associated with regulation of systemic acquired resistance, response to microbial phytotoxin, nuclear transport, and signaling. In tomato, it has been linked to disease resistance against Pseudomonas syringae pv. tomato DC3000. The gene is also associated with drought tolerance, herbivore resistance, and jasmonic acid/salicylic acid hormonal crosstalk. Studies of related genes in other species link them to pathogen resistance, systemic acquired acclimation to high light stress, and salt stress tolerance.
