SummaryToxicity of ethanol on three different plant systems has been evaluated. The growth of Hehanthus tuberosus discs grown in vitro was inhibited more then 50 % by 8.5 mM ethanol. Induction of α-amylase by GA3 in barley aleurone layers was strongly reduced by 34 mM ethanol. Effects of ethanol on single protoplasts were observed using carrot cell cultures. While protoplast viability was only slightly affected by ethanol, the process of embryogenesis showed an high sensitivity to it being arrested at 10 mM concentration of ethanol. Results are discussed in relation to previous data reported in literature.

Review Effect of alcohol on cellular membranesD B Goldstein. Ann Emerg Med. 1986 Sep. AbstractEthanol disrupts the physical structure of cell membranes. The most fluid membranes, including those that are low in cholesterol, are the most easily disordered by ethanol. Although the membrane-disordering effect is small, there is pharmacological, temporal, and genetic evidence that it is important. Animals that are resistant to ethanol intoxication because of their genetic background or because of previous exposure to ethanol are found to have brain membranes that are not easily disordered in vitro. An exception is the increased behavioral sensitivity in aging animals, which is not matched by changes in their membranes. When animals are treated chronically with ethanol, their membranes become stiffer, a response that can be regarded as adaptive. Ethanol may favor the uptake of cholesterol or saturated fatty acids into membranes, thus reducing its own effect. Similar articles

Is ethanol good for plants?It turns out that a tipple may be just what plants need too. A peer-reviewed study published Thursday in the journal Plant and Cell Physiology suggests that ethanol -- or alcohol -- can help plants survive in times of drought, even for as long as two weeks without water.
Is ethanol toxic to cells?Ethanol and methanol showed non-toxic effects on those cell lines at the concentrations of 1.25%-0.15%. Some toxicity was tolerable when a control sample with solvent alone was used in experiments.
Can ethanol enter the cell membrane?Ethanol diffuses through cell membranes
The biological membrane structure allows small, uncharged molecules like ethanol, CO2 and H2O to pass directly through the membrane by the process of diffusion.
