EJ2 — Solanum lycopersicum

Summary

SOLYC03G114840.3 (EJ2) on tomato chromosome 3 encodes a protein with MADS-box and K-box domains, possessing transcription regulator, DNA-binding, and protein dimerization activities. In tomato, EJ2 is associated with leaf and root development, flowering, sepal growth, and plant height. The gene is linked to diverse processes including serotonin metabolism, glycosaminoglycan breakdown, cellular water homeostasis, regulation of seed development and maturation, fruit abscission, and responses to biotic stimuli. EJ2 localizes to the nucleus, cytosol, plastid, and plasmodesmata, and is found in ISWI-type and INO80 complexes. Associations with traits include floral organ morphology, inflorescence branching, fruit ripening, seed coat color and hardness, plant male sterility, and osmotic adjustment capacity. Studies of related genes in other species link the family to seed pigmentation, endothelium development, and floral organ identity.
