NOR — Solanum lycopersicum

Summary

SOLYC10G006880.3, known as NOR, encodes a NAC domain-containing transcription factor on tomato chromosome 10. The protein localises to the nucleus and has sequence-specific DNA-binding activity. This gene is associated with a wide range of biological processes, including ethene metabolism, abscisic acid homeostasis, carotenoid metabolism, ascorbate biosynthesis, and pigment anabolism. It is linked to numerous fruit traits, such as ripening, colour, firmness, weight, shape, size, sugar content, and yield, as well as seed maturation, leaf senescence, and disease tolerance. Associations also include fruit cuticle formation, wax accumulation, glycoalkaloid accumulation, and susceptibility to Botrytis cinerea. Related genes in other species, including NAM-B1 and GPC-B1, connect the family to senescence and nutrient remobilisation, though these functions are not yet established in tomato.
