    摘要: This disclosure describes genetically modified photosynthetic microorganisms, e.g., Cyanobacteria, that overexpress an acyl-acyl carrier protein reductase (acyl-ACP reductase). These microorganisms may optionally overexpress one or more fatty acid synthesis proteins such as ACP and ACCase, and/or one or more polypeptides associated with glycogen breakdown. Also included are photosynthetic microorganisms comprising mutations or deletions in a glycogen biosynthesis or storage pathway, which accumulate a reduced amount of glycogen under reduced nitrogen conditions as compared to a wild type photosynthetic microorganism. The modified photosynthetic microorganisms provided herein are capable of producing increased amounts of lipids such as fatty acids or wax esters and/or synthesizing triglycerides.
