Malic acid peroxidase gene related to saline-alkaline stress tolerance and application of malic acid peroxidase gene

The invention belongs to the technical field of gene engineering, and particularly relates to a malic peroxidase gene related to saline-alkaline stress resistance and application thereof. The nucleotide sequence of the malic peroxidase gene (HVUL2H37793.2 gene) related to saline-alkaline stress tolerance is as shown in SEQ ID NO. 1 (sequence identifier number 1). The research finds that after saline-alkali stress, the HVEL2H37793.2 gene can obviously regulate and control the accumulation level of malic acid in a highland barley resistant variety, so that the saline-alkali tolerance of highland barley is improved. After the gene HVUL2H37793.2 is over-expressed in tobacco, the content of malic acid in tobacco leaves is remarkably increased, and the saline-alkaline tolerance of the tobacco is improved. Therefore, the gene HVUL2H37793.2 has important significance in the salt and alkali stress resistance of the plant. 本发明属于基因工程技术领域，具体涉及一种与耐盐碱胁迫相关的苹果酸过氧化物酶基因及其用途。与耐盐碱胁迫相关的苹果酸过氧化物酶基因(HVUL2H37793.2基因)的核苷酸序列如SEQ ID NO.
