PIP2 — Medicago truncatula

Summary

MTR_4G095002, designated MtPIP2, encodes a member of the PIP2/PIPL1 family. The gene is associated with water transport, macroautophagy, autophagy, regulation of developmental and root development processes, cold acclimation, defense response to other organisms, cellular response to hypoxia, nodulation, innate immunity, response to auxin, and response to thirst. It is linked to the apoplast and mitochondria. Associations with traits include specific leaf weight, leaf weight, photosynthetic rate, ethylene sensitivity, leaf size, and drought tolerance, as well as root hydraulic conductivity and salt tolerance. Studies of related genes in other species connect the family to water absorption by seed, cell membrane stability, drought recovery, leaf water potential, transpiration rate, stomatal resistance, and root length.
