IP21 — Solanum lycopersicum

Summary

SlIP21 (SOLYC03G020050.3) on tomato chromosome 3 encodes a protein with serine-type endopeptidase inhibitor activity, belonging to the protease inhibitor I20 family. The gene is associated with diverse biological processes including response to insects, induced systemic resistance, jasmonic acid and ethylene anabolism, gibberellin biosynthesis, nitrogen fixation, oviposition, syngamy, metabolic burst, chemoattraction, action potential, detoxification, and protein repair. It is linked to extracellular localisation and to traits such as leaf weight, leaf temperature, transpiration rate, ethylene sensitivity, and seed dormancy. Studies of related genes in other species connect the family to plant height, seed weight, germination rate, and potassium concentration.
