PAT4 — Oryza sativa Indica Group

Summary

BGIOSGA003259 (PAT4, OiPAT4) on chromosome 1 of Indica rice encodes a protein-cysteine S-palmitoyltransferase (EC 2.3.1.225) belonging to the DHHC palmitoyltransferase family. This gene is associated with upregulation of the response to oxidative stress, fermentation, starch metabolism, protein membrane targeting, activation of the salinity response, chlorophyll breakdown, and signal transduction. It is linked to submergence tolerance, salinity tolerance, grain yield, panicle weight, and panicle length. PAT4 has been connected to root hair growth, pollen tube guidance, seed set, and nucleus positioning during root hair growth. The encoded protein localizes to the endomembrane system, endoplasmic reticulum, Golgi complex, mitochondria, plasma membrane, nucleus, and TGN transport vesicle. Related genes in other species are linked to root hair elongation and seed dormancy.
