摘　　要：利用边际土地种植能源植物对解决制约我国生物质产业发展的最大瓶颈——原料不足问题具有重要意义,提高抗逆植物种子含油量对发挥其能源价值尤为重要。文章综述了基因调控植物种子含油量的研究进展,包括反义PEP基因、脂肪酸合成基因、三酰甘油合成关键酶基因和影响甘油-3-磷酸水平关键酶基因等。根据滩涂能源植物海滨锦葵种子油品质特性、种子蛋白质和脂肪酸含量关系及基因调控种子含油量的发展趋势,提出了利用源汇基因强化技术提高海滨锦葵种子含油量的遗传改良策略。Energy plants is the important resource of bio diesel production, and the planting of energy plants in marginal land has important significance for resolving the problem of raw material shortage that restricts the development of bio-energy industry in China. At present, improvement of seeds oil content of some energy plants is especially important for exerting their energy value. We outline the status of genetic regulation for seeds oil content, including anti-PEP gene, genes involved in the biosynthesis of fatty acids for triacylglycerol assembly, key enzyme gene that controls the triacylglycerol biosynthesis and affects the level of the glycerol-3-phosphate. According to the quality characteristics of biodiesel from the seeds of K. virginica, relationship between protein content and fatty acid content in seeds, and status of genetic regulation for oil content control, we proposes the improvement strategy of increasing the oil content in Kosteletzkya through genetic enhancement technology.
