Activation energies (<i>Ea</i>) of water transport in <i>V. vinifera</i> aquaporins expressed in yeast. Farzana Sabir Maria José Leandro Ana Paula Martins Maria C. Loureiro-Dias Teresa F. Moura Graça Soveral Catarina Prista 10.1371/journal.pone.0102087.g005 https://plos.figshare.com/articles/figure/_Activation_energies_Ea_of_water_transport_in_V_vinifera_aquaporins_expressed_in_yeast_/1135411 <p>(A) Arrhenius plot of <i>P<sub>f</sub></i> at temperature range (9–37°C), where T is temperature in Kelvin. <i>Ea</i> was evaluated from the slopes. Strains expressing <i>Vv</i>TnPIP1;4, <i>Vv</i>TnTIP4;1 and empty plasmid (pUG35) showed steeper slope, while strains expressing <i>Vv</i>TnPIP2;1, <i>Vv</i>TnTIP1;1 and <i>Vv</i>TnTIP2;2 exhibited shallow slope. (B) Calculated <i>Ea</i> from the slope showed that <i>Vv</i>TnPIP2;1, <i>Vv</i>TnTIP1;1 and <i>Vv</i>TnTIP2;2 expressing strains exhibited lower <i>Ea</i>, while <i>Vv</i>TnPIP1;4, <i>Vv</i>TnPIP2;3 and <i>Vv</i>TnTIP4;1 expressing strains showed were almost equal to control strain (pUG35). Data are mean ± SD of three independent experiments with at least five traces (ten traces in case of <i>P<sub>f</sub></i> at 23°C) at each temperature.</p> 2014-08-11 03:38:13 agriculture biophysics biotechnology Applied microbiology Plant science Plant physiology Drought adaptation Solute transport energies aquaporins
