Inhibition of water channels by HgCl2 in intact wheat root cells

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
To assess the extent of water flow through channels in the membranes of intact higher plant cells, the effects of HgCl2 on hydraulic conductivity (LP) of wheat (Triticum aestivum L.) root cells were investigated using a pressure probe. The LP of root cells was reduced by 75% in the presence of 100 &mgr;M HgCl2. The K+-channel blocker tetraethylammonium had no effect on the LP at concentrations that normally block K+ channels. HgCl2 rapidly depolarized the membrane potential (Vm) of the root cells. The dose-response relationship of inhibition of LP and depolarization of Vm were not significantly different, with half-maximal inhibition occurring at 4. 6 and 7.8 &mgr;M, respectively. The inhibition of LP and the depolarization of Vm caused by HgCl2 were partially reversed by beta-mercaptoethanol. The inhibition of LP by HgCl2 was similar in magnitude to that caused by hypoxia, and the addition of HgCl2 to hypoxia-treated cells did not result in further inhibition. We compared the LP of intact cells with that predicted from a model of cortical cells incorporating water flow across both the plasma membrane and the tonoplast using measured values of water permeability from isolated membranes, and found that HgCl2 has other effects in addition to the direct inhibition of water channels.
