Plastid-expressed choline monooxygenase gene improves salt and drought tolerance through accumulation of glycine betaine in tobacco
J Zhang, W Tan, XH Yang, HX Zhang - Plant cell reports, 2008 - Springer
Glycine betaine (GlyBet), a quaternary ammonium compound, functions as an
osmoprotectant in many organisms including plants. Previous research has shown that over-
expression of enzymes for GlyBet biosynthesis in transgenic plants improved abiotic stress
tolerance, but so far no study on the effects of plastid-expression of choline monooxygenase,
the enzyme that catalyzes the conversion of choline into betaine aldehyde, has been
reported. In the present study, tobacco (Nicotiana tabacum L. cv Wisconsin 38) plants were …
