Betaine-aldehyde dehydrogenase from amaranth leaves efficiently catalyses the NAD-dependent oxidation of dimethylsulfonioproprionaldehyde to dimethylsulfonioproprionate
-
of special interest. Betaine aldehyde dehydrogenase catalyses the last step of glycine betaine synthesis. This paper, along with Trossat 1997 [36], shows that its substrate specificity is much wider. The enzyme can oxidise a number of physiologically-relevant aldehydes. The enzyme may, therefore, have been co-opted for synthesis of dimethylsulfonioproprionaldehyde (DMSP), a relatively uncommon compatible solute, whose synthesis may have evolved independently in a number of genera.

Expression of a betaine aldehyde dehydrogenase gene in rice, a glycinebetaine nonaccumulator, and possible localization of its protein in peroxisomes
-
of special interest. Betaine aldehyde dehydrogenase is expressed in rice, a species which does not accumulate glycine betaine. Suprisingly, it is localised in peroxisomes; it is a chloroplastic enzyme in glycine betaine accumulating plants. This may reflect a wider role for the enzyme [35,36]. Exogenous glycine betaine aldehyde was converted to glycine betaine, showing that the enzyme is functional and the resulting plants were reported to be more salt tolerant.

Expression of the yeast trehalose-6-phosphate synthase gene in transgenic tobacco: Pleiotropic phenotypes include drought resistance
-
of special interest. Trehalose is well-established as a desiccation protectant in microbes and animals. In vascular plants it occurs in a few species with desiccation tolerant leaves ('resurrection plants'). This paper shows that trehalose accumulation can be engineered by introduction of the yeast trehalose-6-phosphate synthase gene (TPS1). Trehalose was detected in the transgenic plants and there were pleiotropic effects: particularly stunted growth. This suggests that trehalose is not universally compatible. The transgenic plants also survived and recovered from severe drought better than wild type plants. The apparent increased drought resistance needs further investigation because the severe growth inhibition make the results difficult to interpret.

Inhibition of trehalase activity enhances trehalose accumulation in transgenic plants
-
of outstanding interest. Trehalose is well-established as a desiccation protectant in microbes and animals. In vascular plants it occurs in a few species with desiccation tolerant leaves ('resurrection plants'). This paper shows that trehalose accumulation in tobacco and potato can be engineered by introduction of E. coli genes ostA and ostB, which encode trehalose-6-phosphate synthase and trehalose-6-phosphate phosphatase. There were pleiotropic effects: particularly stunted growth. This suggests that trehalose is not universally compatible. Inhibition of endogenous trehalase activity by validamycin A increased trehalose accumulation in the transgenic plants and also to a smaller extent in wild type plants. Plants may, therefore, contain trehalase. Furthermore, ESTs with homology to ostA and ostB have been detected in Arabidopsis. This suggests that plants do have a capacity to synthesise and metabolise trehalose; however, its function needs to be determined.

Increased resistance to oxidative stress in transgenic plants by targetting mannitol biosynthesis to chloroplast
-
of outstanding interest. Mannitol, a compatible solute accumulated by some plants during drought, is also an effective hydroxyl radical scavenger in vitro (Smirnoff and Cumbes 1989, [44]). This paper shows that transgenic tobacco engineered to accumulate mannitol in its chloroplasts is more tolerant to photo-oxidative stress and contains lower levels of hydroxyl radicals. The results demonstrate the potential for mannitol to protect against hydroxyl radicals formed in vivo in chloroplasts as a result of oxidative stress.

An Arabidopsis photolyase mutant is hypersensitive to ultraviolet-B radiation

of special interest. This paper describes an Arabidopsis mutant (uvr2), which is highly sensitive to UV-B radiation. The mutant lacks the ability to repair cyclobutane pyrimidine dimers (CPDs) resulting from UV-B induced DNA damage. Extracts from the mutant leaves lacked CDP photolyase activity showing that this DNA repair enzyme is essential for survival of UV-B exposure.

An enzyme similar to animal type II photolyase mediates photoreactivation in Arabidopsis

PCR was used to clone the photolyase using primers based on animal type II photolyase.

Salinity and drought tolerance of mannitol-accumulating transgenic tobacco
-
of outstanding interest. This paper reports one of the first attempts to rigorously test the response to drought and NaCl of a transgenic plant engineered to accumulate a compatible solute. Transgenic tobacco expressing the mtlD gene in the cytosol (Tarczynski 1993, [42]) was not more tolerant to these stresses than the wild type in growth experiments. The interpretation of the results was complicated by slower growth rate of the transgenics. This paper highlights the difficulty in assessing tolerance to complex stresses like drought and underlines the need for more sophisticated analysis of transgenic plants.
