Genes encoding critical steps in the synthesis of osmoprotectant compounds are now being expressed in transgenic plants. These plants generally accumulate low levels of osmoprotectants and have increased stress tolerance. 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 sizes.
编码渗透保护剂化合物合成关键步骤的基因目前正在转基因植物中表达。这些植物通常积累低水平的渗透保护剂,并具有增强的胁迫耐受性。因此,下一个优先事项是在不损害其余代谢的情况下,设计出更强的渗透保护剂合成能力。这将需要在对代谢物通量和库大小进行全面分析的指导下,对多个基因进行操作。
