PIP1 — Sorghum bicolor

Summary

SORBI_3004G288700, designated SbPIP1, encodes a protein with aquaporin-like and MIP domains. The product exhibits channel activity, phospholipase D activity, and peptide receptor activity, among other molecular functions. SbPIP1 is associated with cellular water homeostasis, carbon dioxide transport, hydrogen peroxide membrane transport, and phosphatidic acid metabolism. It localizes to the plasma membrane region, plant-type cell wall, and chloroplast envelope. The gene has been linked to numerous agronomically relevant traits including drought stress response, cold stress response, photosynthetic rate, stomatal opening, root hair length, lateral root length, germination rate, flowering time, and disease responses to bacterial and fungal pathogens. Related genes in other species are associated with water transport, drought tolerance, and yield-related traits.
