SUN — Solanum lycopersicum

Summary

Solyc10g079240.2, the tomato SUN gene on chromosome 10, encodes a protein containing an IQ motif EF-hand binding site and the DUF4005 domain. This gene is associated with a wide range of developmental and morphological processes, including fruit, seed, and organ morphogenesis, meristem determinacy, organ growth, and tissue morphogenesis. It is linked to microtubule dynamics, cytoskeleton organization, actin cytoskeleton organization, and microtubule-based movement, as well as calcium transport, cytokinin breakdown, and primary metabolism. The SUN gene is associated with numerous agronomically important traits, including fruit size, shape, weight, and elongation, seed size, weight, and shape, grain size, yield, and heterosis. It is also associated with leaflet morphology, stem thickness, pedicel length, carpel number, and floral organ identity, along with sugar, sucrose, flavonoid, and carotenoid content.
