TL;DR: Arabidopsis thaliana belongs to those plants that do not naturally accumulate glycine betaine, although its genome contains two genes that code for betaine aldehyde dehydrogenases, and it is hypothesized that these genes may serve as detoxification enzymes controlling the level of aminoaldehydes, which are produced in cellular metabolism under stress conditions.

TL;DR: Molecular genetic and biochemical analyses of selected Arabidopsis ALDH genes demonstrated an improved abiotic stress tolerance and Mutational approaches identified amino acid residues critical for coenzyme usage and enzyme activities.

TL;DR: The expression of selected Arabidopsis ALDH genes is induced in response to heat and stress combination, and ALDH mutant lines are more sensitive to heat stress and stress combinations.

TL;DR: The results suggest that a balanced expression of the betaine aldehyde dehydrogenase genes is important for early growth of A. thaliana seedlings and for salt stress mitigation in young seedlings.

TL;DR: A review of the research reports over the last decade on plant ALDHs is presented in this article, where newly discovered roles for these enzymes in metabolism, signaling and development have been highlighted and discussed.
