Several genes coding for enzymes associated with osmotic adjustment are turned on (up-regulated) by osmotic stress and/or salinity, and cold stress. These genes encode enzymes such as the following;

I) ∆′1-Pyrroline-5-carboxylate synthase, a key enzyme in the proline biosynthetic pathway

II) myo-Inositol 6-O-methyltransferase, a rate-limiting enzyme in the accumulation of the cyclic sugar alcohol called pinitol

III) Betaine aldehyde dehydrogenase, an enzyme involved in glycine betaine accumulation
