• Genbank accession number
  • AB009665
• Key message
  • Partial silencing of the water channel genes, OsPIP1;1 and OsPIP1;3, reduced seed germination while over-expression of OsPIP1;3 promoted seed germination under water-stress conditions
  • OsPIP1;1 is one of the most abundant aquaporins in rice leaves and roots and is highly responsible to environmental stresses
  • Moderate expression of OsPIP1;1 increased rice seed yield, salt resistance, root hydraulic conductivity, and seed germination rate
  • Aquaporin OsPIP1;1 promotes rice salt resistance and seed germination
  • Exogenous NO stimulated the transcription of OsPIP1;1, OsPIP1;2, OsPIP1;3 and OsPIP2;8 in germinating seeds

  • OsPIP1;1~RWC1, RWC3~OsPIP1;3, The role of water channel proteins and nitric oxide signaling in rice seed germination, Partial silencing of the water channel genes, OsPIP1;1 and OsPIP1;3, reduced seed germination while over-expression of OsPIP1;3 promoted seed germination under water-stress conditions

  • LP2, OsPIP1;1~RWC1, Plasma membrane receptor-like kinase leaf panicle 2 acts downstream of the DROUGHT AND SALT TOLERANCE transcription factor to regulate drought sensitivity in rice, In addition, LP2 was identified as a functional kinase localized to the plasma membrane and interacted with the drought-responsive aquaporin proteins OsPIP1; 1, OsPIP1; 3, and OsPIP2; 3.
  • OsHIPL1, OsPIP1;1~RWC1, OsHIPL1, a hedgehog-interacting protein-like 1 protein, increases seed vigour in rice., Meanwhile, we found that OsHIPL1 interacted with the aquaporin OsPIP1;1, then affected water uptake to promote rice seed germination
