Molecular regulation and genetic improvement of seed oil content in

Wei HUA,Jing LIU,Hanzhong WANG

《农业科学与工程前沿（英文）》 2016年第3卷第3期页码 186-194 doi: 10.15302/J-FASE-2016107

摘要： As an important oil crop and a potential bioenergy crop, L. is becoming a model plant for basic research on seed lipid biosynthesis as well as seed oil content, which has always been the key breeding objective. In this review, we present current progress in understanding of the regulation of oil content in , including genetics, biosynthesis pathway, transcriptional regulation, maternal effects and QTL analysis. Furthermore, the history of breeding for high oil content in is summarized and the progress in breeding ultra-high oil content lines is described. Finally, prospects for breeding high oil content cultivars are outlined.

摘要： Screening of cost-effective soil amendments is important to develop “ ” remediation techniques for cadmium (Cd) contaminated soils. In this study, different soil amendments, including red mud, a by-product of the alumina industry, and acid-treated, nano-treated by nano-particle milling, nano and acid-treated red muds, zeolite, corn straw, and rape straw, were evaluated to immobilize Cd in two added levels (2 and 5 mg Cd·kg soil) in a calcareous soil by single and sequential extractions and by cucumber ( L.) pot experiments. Results indicated that cruciferous rape straw significantly decreased the concentrations of water soluble, extractable Cd in soils, and Cd in cucumber plants, and it was more effective than gramineous corn straw. Also, red mud generally decreased the extractability and bioavailability of Cd added to calcareous soils more effectively than zeolite. Furthermore, the efficiency of red mud could be increased by the treatment of nano-particle milling due to the increase in specific surface area of red mud. It is potential to use rape straw and red mud as soil amendments to develop a cost-effective and efficient “ ” remediation technology for Cd mildly contaminated calcareous soils.

通过遗传操作提高非典型油料植物作为生产三酰甘油生物工厂的潜力 Review

Xiao-Yu Xu,Hong-Kun Yang,Surinder P. Singh,Peter J. Sharp,Qing Liu

《工程（英文）》 2018年第4卷第4期页码 523-533 doi: 10.1016/j.eng.2018.07.002

摘要：

到2030 年，全球植物油需求量预计将翻番。然而目前的植物油生产平台，包括油棕和温带油籽却难以满足如此的增幅。因此，探索新型植物油来源对弥补未来的植物油的短缺变得越来越重要。植物油的主要形式是三酰甘油（TAG），最近通过基因工程在植物营养组织中生产TAG 引起了人们极大的兴趣。多学科的“组学”研究也愈发提高了我们对植物脂质生物化学和代谢的理解。鉴于此，生物化学途径鉴定及对脂肪酸生物合成、脂质组装和转换关键的基因的注释已得到有效更新。近年来，通过对TAG 生物合成涉及的关键基因和调节因子的遗传操作，高生物量植物营养组织和油籽中TAG 的积累得到了前所未有的迅速发展。本文总结了目前从单基因操作到旨在增加高生物量植物组织中TAG 积累的多基因叠加基因工程策略，讨论了可能有助于进一步缓解食用油和生物柴油潜在短缺的植物油生产的新方向和建议。
