PagPB GENE REGULATING NITROGEN ABSORPTION AND UTILIZATION IN ROOT SYSTEM OF WOODY PLANT AND APPLICATION THEREOF

Abstract

A PagPB gene regulating nitrogen absorption and utilization in a root system of a woody plant is provided. The nucleotide sequence of the PagPB gene is shown in SEQ ID NO: 1. By silencing the PagPB gene, efficiency of the nitrogen absorption and utilization of a root system of poplar can be improved. In contrast, by overexpressing the PagPB gene, the efficiency of the nitrogen absorption and utilization of the root system of the poplar is reduced. This provides significant genetic resources for identification of key regulatory genes involved in the nitrogen absorption and utilization in the woody plant and holds important application value in the fields of forest genetic engineering and clonal forestry.
