Abstract:
Both the fruit flesh and seeds of sea buckthorn have multiple uses for medicinal and culinary purposes, including the valuable market for supplementary health foods. Bioactive compounds, such as essential amino acids, vitamins B, C, and E, carotenoids, polyphenols, ursolic acid, unsaturated fatty acids, and other active substances, are now being analyzed in detail for their medicinal properties. Domestication with commercial orchards and processing plants is undertaken in many countries, but there is a large need for improved plant material with high yield, tolerance to environmental stress, diseases, and pests, suitability for efficient harvesting methods, and high contents of compounds that have medicinal and/or culinary values. Applied breeding is based mainly on directed crosses between different subspecies of Hippophae rhamnoides. DNA markers have been applied to analyses of systematics and population genetics as well as for the discrimination of cultivars, but very few DNA markers have as yet been developed for use in selection and breeding. Several key genes in important metabolic pathways have, however, been identified, and four genomes have recently been sequenced.
摘要:
沙棘的果肉和种子都具有多种药用和烹饪用途,包括有价值的补充保健食品市场。生物活性化合物,如必需氨基酸,维生素B,C,E,类胡萝卜素,多酚,熊果酸,不饱和脂肪酸,和其他活性物质,现在正在详细分析它们的药用特性。在许多国家进行商业果园和加工厂的驯化,但是对高产的改良植物材料的需求很大,对环境压力的耐受性,疾病,和害虫,适用于有效的收获方法,和高含量的具有药用和/或烹饪价值的化合物。应用育种主要基于沙棘不同亚种之间的定向杂交。DNA标记已应用于系统学和群体遗传学的分析以及品种的区分,但是到目前为止,很少有DNA标记被开发用于选择和育种。重要代谢途径中的几个关键基因,然而,被确认,最近对四个基因组进行了测序。
