摘要:从拟南芥和甘蓝型油菜种子制得的总胆碱酯级分通过毛细管lc / Esi-Qtof-Ms和直接输注esi-Fticr-Ms进行分析.除了主要的芥子碱胆碱外,还可以基于精确的质量测量,碰撞诱导解离(cid)质谱的解释以及选定代表的合成,鉴定出30种酚类胆碱酯.迄今为止鉴定出的化合物包括取代的羟基肉桂酰基和羟基苯甲酰胆碱,各自的单己糖苷以及酚类胆碱酯和单木酚的氧化偶联产物.苯酚胆碱酯类可通过反相液相色谱很好地分离,并且可使用电喷雾电离质谱法以正离子模式灵敏地检测到.从分子离子获得的cid质谱图有助于表征此类化合物的类型和取代形式.因此,Lc / Esi-Ms / Ms是对该化合物类别进行全面定性和定量分析的宝贵工具.版权所有©2008 John Wiley&sons,Ltd.

标题 :Altering levels of anti-nutrient factors in plants

摘要:A method for reducing the level of one or more than one protein in a plant or a tissue within the plant, and plants with reduced levels of target proteins are provided. The method involves introducing a nucleic acid sequence into the plant, where the nucleic acid sequence comprises a regulatory region operatively associated with a silencing nucleotide sequence. The expression of the silencing nucleotide sequence reduces or eliminates the expression of two or more than two enzymes involved in the synthesis of the one or more than one protein. The reduced level of the one or more than one protein may be determine by comparing the level of the one or more than one protein in the plant, or a tissue of the plant, with a level of the one ore more than one protein in a second plant, or the tissue from the second plant, that does not express the nucleic acid sequence. Plants and seeds obtained from plants with reduced levels of target proteins, and reduced anti-nutrient factors are also provided

摘要:The present invention relates to plant cell wall synthesis, and to the synthesis of soluble compounds in plants commonly known as secondary metabolites or natural products. In particular, the present invention provides plant aldehyde dehydrogenases with a novel capacity of oxidizing hydroxycinnamaldehydes to hydroxycinnamic acids, and genes encoding the enzyme, as well as variants of the gene, and methods of using the genes and variants of the gene to modify plant chemistry. The methods of the present invention include reducing sinapine content of a seed, decreasing hydroxycinnamic acid content in a plant cell, and modifying lignin property in a plant cell wall by manipulating the activity of the novel plant aldehyde dehydrogenase in a plant cell.

摘要:This invention relates to isolated polynucleotides encoding enzymes consisting of a carboxypeptidase-like protein, a methyltransferase and a glucosyltransferase, involved in the biosynthesis of β-amyrin-derived triterpenes in plants and seeds. The invention also relates to the construction of recombinant DNA constructs comprising all or a portion of the isolated polynucleotides of the invention, in sense or antisense orientation, operably linked to at least one regulatory sequence.
