CNR2 — Solanum lycopersicum

Summary

SOLYC02G090730.3, also known as CNR2 or FW2.2, encodes a PLAC motif-containing protein with calcium channel activity and mRNA binding. In tomato, this gene is associated with fruit size and cadmium detoxification. It localizes to the plasma membrane, nucleus, cytoplasm, vacuole, and extracellular space. The gene is associated with numerous fruit traits such as weight, width, length, shape, firmness, sweetness, and color, as well as grain size, seed weight, plant size, and heterosis. Associations with zinc detoxification, zinc ion homeostasis, and zinc tolerance have also been observed. Studies of related genes in other species connect the family to heavy metal transport and cadmium stress responses.
