Virus induced PsPIP2;1 silencing led to reductions in leaf hydraulic conductivities. a Representative pressure-to-flow relationship measured in leaves of control plants and VIGS-PsPIP2;1 plants. J v represents the rate of exuded sap flow through leaves. b Leaf hydraulic conductivity at organ level. c Typical hydrostatic relaxation curves as measured by a cell pressure probe on leaf cells. d Leaf hydraulic conductivity at the cell level. Values are mean ± SD (n = 6–9 plants or 30–60 cells). Asterisks (*) represent a significant difference between control plants and VIGS-PsPIP2;1 plants at P < 0.05
