【摘要】 亚麻荠(Camelina sativa L.Crantz)是一种新型的"低投入、环保型"工业油料作物。种子含油量达43%,其中α-亚麻酸>35%。种子油不仅可做食用油和动物饲料,亦可用于加工保健功能食品,以及生物燃油和高值油脂产品。我们实验室近年来开展了亚麻荠种子油脂代谢工程研究。本文重点分析亚麻荠主要农艺性状和优异油脂性状,论述应用基因工程技术对亚麻荠油脂品质的遗传改良研究,包括长链多聚不饱和脂肪酸、ω-7脂肪酸,中、短链脂肪酸和蜡酯生物合成.以及单一脂肪酸富集途径的代谢组装。分析和讨论了亚麻荠功能基因组学研究动向以及亚麻荠产业发展前景。更多还原

【Abstract】 Camelina sativa L.Crantz is a new and potential industrial oilseed crop with low input and environment-friendly.The seed yields 43%(WAV) oil with a-linolenic acid content over 35%.The seed oil can be used for edible oil and animal feed,health-promoting food,biofuel oil and high-valued oil chemicals.Our lab conducted a series of metabolic engineering for seed oil improvement in camelina in the past few years.Here,we characterize the important agronomic traits and the excellent oil properties of camelina.Particularly,we describe the genetic improvements of the seed oil quality by gene engineering,which include pathway assembly of long chain polyunsaturated fatty acids,ω-7 fatty acids,wax esters,mediumand short-chain fatty acids,and enrichment of single fatty acid.We also dissect and discuss trends in camelina functional genomics and the prospects for development of camelina commercialization as a new bioenergy oilseed in China.更多还原
