NAM — Solanum lycopersicum

Summary

SlNAM (SOLYC07G062840.3), a tomato gene on chromosome 7, encodes a NAC-domain transcription factor with sequence-specific DNA binding, transcription cis-regulatory region binding, protein homodimerization, and protein binding activities. It is localized to the nucleus and endoplasmic reticulum. SlNAM is associated with leaflet morphogenesis, flower formation, fruit abscission, meristem initiation, organ boundary specification, and regulation of plant organ formation timing. It has been linked to pigment, ethene, oxygen, sucrose, and phospholipid metabolism, as well as lycopene and ATP anabolism. Trait associations include leaflet morphology, leaf margin serration, inflorescence branching, fruit size, seed yield, plant height, root length, drought tolerance, low temperature stress response, water use efficiency, stomatal resistance, proline and sucrose content, cellulose content, and respiration rate. Studies of related genes in other species link the family to cotyledon separation, embryonic shoot meristem formation, and leaf margin dissection.
