摘要

A genetic construct, recombinant vector, method of reduction of nitrate concentration in the leaves of a plant test, method of production of a transgenic plant that carries nitrate, transgenic plant, the use of an exogenous nucleic acid sequence coding a transport Worship of nitrate, host cell, the product of the spread of plant obtained from transgenic plant.The harvested leaf containing the lowest level of nitrate, tobacco product, article for the smoker. The present invention relates to constructos genes that can be used in the preparation of transgenic plants. The constructos may have the ability to reduce the concentration of nitrite in the plant, in particular in the leaves of the plant, and induce a senescence like phenotype.The invention extends to plant cells transformed with such constructos, and said transgenic plants. The invention also relates to methods for producing transgenic plants, and methods to reduce nitrate content in plants.The invention also relates to plant leaves collected from, for example, tobacco leaves, which had been transformed with the genetic constructos, and several articles of tobacco, such as articles for smokers, comprising such leaves of plant harvested.
