PIP1 — Oryza sativa Japonica

Summary

OsPIP1 (OS07G0448800) on rice chromosome 7 encodes an aquaporin with water channel activity, belonging to the MIP (major intrinsic protein) family. It is associated with water transport, membrane transport, pore formation, and response to water, and localises to the plasmalemma and membrane. The gene has been connected to drought stress response in rice, as well as to grain moisture content, grain yield, water use efficiency, transpiration rate, stomatal resistance, photosynthetic rate, rubisco content, chlorophyll content, leaf drying, root volume, nitrogen content, drought sensitivity and tolerance, salinity and cold tolerance, days to heading, anthesis time, floral organ number and identity, and organ identity. Additional associations include protein heterotetramerization and homotetramerization, endocytosis, secretion, the ERAD pathway, the MAPK cascade, RNA processing, homologous recombination, stamen development, syngamy, and hypersensitivity.
