摘要:(+)-Pisatin 由豌豆 (Pisum Sativum L.) 产生,是属于紫檀家族的异黄酮衍生物.这是第一个经过化学鉴定的植物抗毒素,随后的研究表明,大多数豆科植物产生具有相反立体化学的紫檀素.对(+)-Pisatin生物合成的研究表明(-)对映体化合物是(+)-Pisatin合成的中间体.然而,从(-)-7,2'-二羟基-4',5'-亚甲二氧基异黄酮[(-)-槐酚]中间体到(+)-6A-羟基槐素中间体的步骤尚未确定.使用硼氢化钠 (Nabh4) 对 (-)-槐酚进行化学还原,反应生成(-)-7,2'-二羟基-4',5'-亚甲基二氧基异黄醇 [(-)-Dmdi] 的两种异构体,其最佳紫外吸光度为 299.3 和分别为 300.5 Nm.相反,通过豌豆酶槐醇还原酶 (Sor) 酶促还原 (-)-槐酚仅产生 299.3 Nm (-)-Dmdi 异构体. 299.3 Nm (-)-Dmdi

摘要:The invention is related to compositions and methods that naturally protect plant tissues against ultraviolet radiation and temperature, thus giving protection against sunburn to plants, plant parts, fruits and/or flowers during their development. The invention is also related to compositions and methods to naturally improve the color of plants, plant parts, fruits and/or flowers by inducing the natural synthesis of flavonoids and anthocyanins present in plants. Likewise, the present invention is directed to improving the nutritional value of plants, plant parts, fruits and/or flowers by increasing the normal levels of polyphenolic compounds, especially flavonoids, present therein. Additionally, the present invention is related to compositions and methods that give more resistance to plants, plant parts, fruits and/or flowers against pathogens as bacteria and fungi. Finally, the present invention is related to plants, plant parts, fruits, flowers and/or propagating material treated with the compositions described in the present document.

摘要:The invention provides methods and compositions for making a dicotyledonous plant that is susceptible to Phymatotrichopsis Root Rot (PRR) more resistant to PRR, by metabolic engineering of the plant's flavonoid and isoflavonoid biosynthetic pathways. Thus, methods for increasing the synthesis and accumulation of medicarpin and/or 7,4′-dihydroxyflavone in plants such as alfalfa are provided.
