CBL7 — Solanum lycopersicum

Summary

SlCBL4 (CBL7, SlSOS3) on tomato chromosome 3 encodes a calcineurin B-like protein with EF-hand domains that binds calcium ions and kinases. The gene is associated with salt tolerance, calcium signaling, and the MAPK cascade, as well as stomatal closure, detoxification, and responses to stress. It has been linked to plastid localization, extracellular transport, and regulation of growth, including downregulation of growth. Associations with agronomic traits include fruit weight, plant height, root length, sepal and stamen length, relative yield, germination rate, net photosynthetic rate, quantum yield, chlorophyll content, anthocyanin and flavonoid content, sodium content, and salt tolerance. The product localizes to the plasmalemma and aleurone grain membrane and is connected to polyamine and sulfur metabolism, phenylpropanoid and flavonoid anabolism, and virus-induced PTGS.
