Nitrate transporter gene AtNRT1.5, and coding protein and application thereof
The invention belongs to the field of plant molecular biology, and specifically relates to functional verification of arabidopsis thaliana nitrate transporter gene AtNRT1.5. A function of the gene in efficient utilization of plant nitrogen is studied by inserting T-DNA of the AtNRT1.5 gene into a homozygous line of a mutant CS870797. Experimental results show that the growth of the mutant on a high-nitrogen (MS) medium is inhibited; the root system of the mutant is obviously shorter than that of the wild type; and in a low nitrogen condition, the growths of the root systems of the mutant and the wild type have no difference, but dry weight of the mutant is lower than that of the wild type. Determination results of nitrogen content show that the nitrogen content in the root system of the mutant is higher than that of the wild type while the nitrogen content in the shoot is significantly lower than that of the wild type; and the difference is more obvious on the high nitrogen (MS) medium. The results demonstrate that after mutation of the ATNRT1.5 gene, nitrogen uptake capacity of the root system is not affected significantly while transportation capacity of the nitrogen from roots to shoots is reduced significantly. Over-expression of the gene is expected to improve the nitrogen utilization capability of plants and has relatively large economic value in plant nitrogen nutrition efficient molecular breeding.

Through insertion of arabidopsis AtNRT1.1 gene T-DNA into a homozygous strain of a mutant salk_138710, functions of the AtNRT1.1 gene at aspects of plant low-nitrogen tolerance and efficient utilization of nitrogen are researched.

Under treatment condition of else addition of 0.1 nM and 5 mM of ammonium nitrate, the nitrogen content of the mutant root is higher than that of the wide type but the nitrogen content of the overground part is obviously lower than that of the wide type (P is equal to 0.0001), which shows the AtNRT1.1 gene has important regulation and control effects on nitrogen element absorption and transportation under different concentrations, and predicts that the silencing of the gene can raise plant low-nitrogen tolerance ability and has great economic value in plant nitrogen nutrition efficient molecular breeding.
