PIP1-1, PIP1-2, PIP1-3, PIP1-4, and PIP1-5 encode plant plasma membrane intrinsic protein (PIP1) aquaporins that are targeted predominantly to the plasma membrane, where they contribute to transmembrane movement of water and, for some isoforms, additional small neutral substrates such as CO2. Structurally, PIP1 proteins are typical major intrinsic proteins with six membrane-spanning helices, five connecting loops (including two half-helices bearing the conserved NPA motifs that meet in the membrane to form the pore), and cytosolic N- and C-termini; they assemble as tetramers in the membrane, with each monomer forming an individual channel whose permeability and trafficking can be tuned by post-translational regulation and by hetero-oligomerization with PIP2 aquaporins. Functionally, PIP1 isoforms act as key components of cellular and tissue hydraulic conductivity and can influence organ-level water relations and growth; for example, genetic disruption of PIP1-2 reduces root hydrostatic hydraulic conductivity, consistent with a role in pressure-driven water transport, and PIP1-4 has been implicated in plasma-membrane CO2 and H2O permeability with downstream effects on photosynthetic performance, illustrating that PIP1 channels can couple membrane transport capacity to physiological outputs such as gas exchange, carbon assimilation, and stress-responsive water management.
