Metabolic engineering of plants for osmotic stress resistance

Metabolic engineering of plants for osmotic stress resistance Curr Opin Plant Biol. 1999 Apr;2(2) :128-34. doi ... The next priority is therefore to engineer greater osmoprotectant synthesis without detriment to the rest of metabolism. This will require manipulation of multiple genes, guided by thorough analysis of metabolite fluxes and pool ...

Metabolic Engineering of Osmoprotectant Accumulation in Plants

2002-1-1  First-generation engineering work—much of it with single genes—has successfully introduced osmoprotectant pathways into plants that lack them naturally, and this has often improved stress tolerance. However, the engineered osmoprotectant levels are generally low and the increases in tolerance commensurately small.
