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:Provided are transgenic organisms, such as plants and plant parts, cells, and related compositions and methods for producing and monitoring the genotype for enhanced production of montbretin A and/or its precursors. For example, provided is a transgenic organism comprising at least one heterologous nucleic acid operatively linked to a promoter, wherein the heterologous nucleic acid encodes at least one enzyme in a montbretin A (MbA) metabolic pathway. The organisms can be a plant, plant part, or plant cell, or a microorganism such as a yeast. Also provided is a method for producing at least one montbretin A (MbA) precursor and/or MbA, comprising permitting the expression of the at least one heterologous nucleic acid in the transgenic organism. The disclosure also provides isolated nucleic acid molecules that comprise sequence encoding at least one enzyme in a montbretin A (MbA) metabolic pathway and vectors comprising the nucleic acids.
