RSH3 — Solanum lycopersicum

Summary

SlRSH3 (Solyc12g017390) on tomato chromosome 12 encodes a protein with serine/threonine kinase activity, 3-phosphoinositide-dependent protein kinase activity, and protein kinase activator activity, and it also exhibits blue light photoreceptor activity and phosphatidate binding. The protein localises to the plasma membrane, cytoplasm and nucleus. SlRSH3 is associated with sepal formation, ethene metabolism, TOR signalling, response to carbohydrate, and tryptophan breakdown. It has been linked to fruit firmness, fruit colour and shape, flower abortion, leaf chlorophyll content, net photosynthetic rate, water use efficiency, drought tolerance, plant height, stem diameter, root length, and sodium content. Associations with pollen germination, male fertility, auxin transport, and vascular development have also been reported.
