    摘要:

    菥蓂(Thlaspi arvense L.)属于十字花科菥蓂属,是一种兼具药食同源功效的草本植物,生态适应能力强,种子富含油脂,具备较高的资源开发利用价值。近年来,随着现代生命科学研究的不断进步,菥蓂的诸多优势得以被发掘,国内外已陆续开展了关于菥蓂的基础和应用研究。目前国内的报道多集中于菥蓂的功能活性物质提取及其在临床医疗上的作用,国外研究则偏向于探索菥蓂在农业生产循环中的生态价值与脂质代谢调控机制。大量研究表明,菥蓂具备开发生物柴油和补充油料生产的优异潜质,也是新型药物开发的良好备选原料。同时,得益于菥蓂全基因组信息的公布,对菥蓂开展分子育种改良已成为可能,例如通过基因编辑技术改变其种子脂肪酸构成以获得更符合食用油需求的品质,以及挖掘菥蓂的其他重要功能基因用于提高作物生产和抗逆性。利用代谢工程手段优化菥蓂的脂质特性以制备新型植物油甚至异源生产高价值脂肪酸(神经酸等)将潜力巨大,是菥蓂最具前景的开发方向之一。本文综述并展望了近年来菥蓂在资源开发利用和脂质代谢工程研究等方面的报道,以期为菥蓂在我国的基础研究和推广应用提供参考。

    Abstract:

    Pennycress (Thlaspi arvense L.) belongs to the Thlaspi genus of the Cruciferae family, which is a dual-role herb plant with both medical and food usages. Pennycress has strong ecological adaptability and can accumulate abundant oil in the seed, hence displaying great values in the resource development and utilization. In recent years, with the rapid progress made in the modern life science research, advantages of pennycress were broadly investigated, a variety of fundamental and application researches have thus been conducted. In this respect, the domestic reports about pennycress in China were mainly focused on the extraction of functional active substances and their clinical effects, while the studies developed abroad preferred to explore its ecological value in the agricultural production cycle and the lipid metabolism regulatory mechanisms. Numerous researches have both indicated that pennycress not only possess great potentials in the biodiesel preparation and support the oil supplement, but also could serve as a favorable candidate in the novel medicine development. Meanwhile, being benefited from the publishing of the whole genome information of pennycress, it has become possible to carry out the molecular breeding improvement. For example, the genome editing technology was successfully applied to alter the pennycress seed fatty acid composition to achieve a more desirable trait to meet the edible oil demand, not to mention the mining of other useful functional genes within pennycress that may assist the crop production and stress resistance amelioration. Metabolic engineering of the pennycress lipid property in order to develop novel vegetable oil, or even heterologously produce high-value fatty acid (e.g. nervonic acid etc.) has shown great prospect as one of the pennycress development directions. This paper therefore summarized and envisaged the recent progresses of the resource development and utilization and the lipid metabolic engineering on pennycress, aiming to provide reference for the study, popularization and application of pennycress in China.
