PIP2 — Pisum sativum

Summary

PsPIP2 (PSAT6G218680) on garden pea chromosome 6LG2 encodes a PIP2/PIPL1 family protein. The gene is associated with water transport, regulation of developmental and root development processes, defense responses to other organisms, innate immunity, cellular response to hypoxia, heat acclimation, response to auxin and heat, and virus-induced PTGS. The product localises to the apoplast and mitochondria. PsPIP2 is linked to water absorption by seed, photosynthetic rate, ethylene sensitivity, root hydraulic conductivity, and salt tolerance. Studies of related genes in other species connect the PIP2 family to drought tolerance and recovery, leaf water potential, transpiration rate, stomatal resistance and opening, cell membrane stability, chlorophyll content, leaf weight and size, root length and morphology, and salt response.
