  "summary": "Aquaporins at the plant plasmalemma are divided into two highly conserved subclasses, PLASMA MEMBRANE INTINSIC PROTEINs 1 (PIP1) and PIP2. Arabidopsis thaliana encodes five PIP1 and eight PIP2 isoforms. Individual loss-of-function mutants had been employed for functional analyses. Here, we observe that the pip2;1 pip2;2 pip2;4 pip2;6 pip2;7 quintuple mutant defective of major PIP2 isoforms…",
