Abstract
The effects of light and of water stress in plant growth are well documented but less is known about their effects on plant enzymes. Chloroplast thylakoid membrane organization is particularly sensitive to light. The biosynthesis of galactolipids, the major acyl lipids of these membranes, is much investigated. However it is not known whether the enzymes involved are constitutive or inducible or are capable of being modulated directly by environmental factors. We wish to report some very preliminary data on UDPgalactosyl transferase (UDPgalT) activity (and thus indirectly on intergalactolipid transferase (IGT) activity) in plastids in relation to (1) the osmotic concentration (OC) of incubation media and (ii) the light regime in which plants were grown.
