Abstract: SUMMARYAquaporins facilitate water transport over cellular membranes, and are therefore believed to play an important role in water homeostasis. In higher plants aquaporin-like proteins, also called major intrinsic proteins (MIPs), are divided into five subfamilies. We have previously shown that MIP transcription in Arabidopsis thaliana is generally downregulated in leaves upon drought stress, apart from two members of the plasma membrane intrinsic protein (PIP) subfamily, AtPIP1;4 and AtPIP2;5, which are upre… Show more

“…In higher plants aquaporin-like proteins, also called major intrinsic proteins (MIPs), are divided into five subfamilies. The MIP-PIP subfamily was over expressed in genotype 10 and was supported by previous reports in Arabidopsis (Alexandersson, 2010). The plasma membrane intrinsic protein (PIP) subfamily generally upregulated in leaves upon drought stress.…”

“…The differences in low-roottemperature responses between the PIP1;4-and PIP2;5-overexpressing plants may reflect functional differences between the two aquaporins (Jang et al, 2004(Jang et al, , 2007Alexandersson et al, 2005;Wudick et al, 2009;Almeida-Rodriguez et al, 2010) or the differences in tissue distribution Suga et al, 2003;Da Ines, 2008;Alexandersson et al, 2010). However, they may also reflect possible differences in regulation mechanisms between PIP1;4 and PIP2;5 or in their water-transporting effectiveness, assuming no major differences in PIP1;4 and PIP2;5 membrane density in plants overexpressing the respective aquaporins.…”

“…Cycle time for all replicates was 95°C for 2 min followed by 40 cycles of 95°C for 15 s, 60°C for 15 s, and 72°C for 45 s. Data were analyzed by two-way ANOVA using Prism 4 (GraphPad Software) with outliers removed by Grubb's test (a = 0.05) utilizing the QuickCalcs online outlier calculator (GraphPad Software; http://www.graphpad.com/quickcalcs/Grubbs1.cfm). Aquaporin homolog primers were used are described (Alexandersson et al, 2010). All primer sets utilized are listed in Supplemental Table S2.…”
