Interesting article.

bae mentioned in his response three techniques plants use:
dehydration
moving water to intercellular spaces
increasing solute concentration, for example by storing
monosacharides
in place of disacharides.

One more technique identified in the article was expression of a
polypeptide that decreased "the propensity of membranes to form
deleterious hexagonal II phase lipids upon freeze-induced
dehydration".

Just think what Lysenko would have given to know about all this :^)

Thanks.
