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.

标 题:Nutrient and therapeutic compositions for the treatment of cancer
权利人:KOSBAB JOHN V
摘要:This invention relates to nutrient and therapeutic compositions for the treatment of cancer symptoms and conditions. Compositions of this invention contain a mixture of antioxidants, components that promote collagen maintenance and synthesis, components that regulate blood lipids, glucose and/or insulin, and lower homocysteine levels. Compositions also provide supplementation for nutrient (vitamin, mineral and cofactor) deficiencies to restore and maintain normal biochemical function. Cancer formulations, particularly those adapted for treatment of female cancers, can be combined with components that provide benefit in osteoporosis.

摘要:The purpose of the present invention is to provide a plant having an improved production amount of a useful substance. The present invention is a method for producing a useful substance by cultivating a plant or the like in which the expression of a granule bound starch synthase (GBSS) gene and/or a starch branching enzyme (SBE) gene, which is a gene involved in starch synthesis, is suppressed, and inducing a lipid-storing organelle into a cell.
