DS2 — Solanum lycopersicum

Summary

SlDS2 (SOLYC04G071610.4) on tomato chromosome 4 encodes an ABA/WDS-domain protein with nucleic acid, sequence-specific DNA and identical protein binding activities, and zinc binding. The gene is associated with a wide range of processes including carotenoid and glucose metabolism, pigmentation, petal development, and traits such as petal and flower colour, fruit size, anthocyanin and proline content, stomatal resistance and opening, root branching and length, stem diameter, drought tolerance, and salt tolerance. It is also linked to protein denaturation, macromolecule breakdown, N-glycan processing, fermentation, sexual reproduction, nuclear import, demethylation, the shikimate pathway, mitosis, vernalization response, and autotrophy. The product localises to the cytoplasm, nucleus, and macromolecular complexes. Studies of related genes in other species connect the family to tuber fresh weight and size.
