DIG3 — Solanum lycopersicum

Summary

SOLYC07G062970.3, also known as DIG3 or SlPIA1, encodes a protein serine/threonine phosphatase belonging to the PP2C and PPM-type phosphatase families. This tomato gene on chromosome 7 is associated with fruit abscission, organ growth, chlorophyll metabolism, zeatin and melatonin anabolism, response to boron, and oxidative phosphorylation. The encoded protein localizes to the chloroplast membrane, plastid, mitochondria, and stress granules. DIG3 is linked to fruit weight, fruit firmness, fruit size, sugar content, plant height, stem diameter, root weight, root hair density and length, seed longevity, germination rate, photosynthetic rate, stomatal resistance, drought tolerance, and salt tolerance. It is also associated with altered fatty acid ratios in plastidic lipids, viral resistance, defense gene expression, and heat stress response.
