Abstract

The invention discloses a nitraria tangutorum CBL-interacting protein kinase 9 (NtCIPK9) gene, expressed protein of the NtCIPK9 gene and application of the NtCIPK9 gene. The nucleotide sequence of the NtCIPK9 gene is shown as the SEQ ID NO.1, and the amino acid sequence of the NtCIPK9 gene is shown as the SEQ ID NO.2. According to the NtCIPK9 gene, a full-length gene related to stress resistance of nitraria tangutorum is cloned in a homological mode by using leaf blade tissue of the nitraria tangutorum on the basis of a part of existing transcriptome data according to the stress resistance characteristic of the nitraria tangutorum, and is named NtCIPK9 according to a homologous gene in arabidopsis. The function of plant salt tolerance of the NtCIPK9 gene is proved through analysis of salt tolerance of an NtCIPK9 gene homozygous arabidopsis plant, and resources are increased for a plant stress resistance gene pool.

Description

technical field

[0001] The invention belongs to the technical field of plant genetic engineering, in particular to a Nitraria tangutata NtCIPK9 Genes and their expressed proteins and applications. Background technique

[0002] Nitraria tangutica ( Nitraria tangutorum ) belongs to the genus Nitraria (Zygophyllaceae) of the family Zygophyllaceae ( Nitraria ), a strong xerophytic deciduous shrub, is a unique Nitraria species in my country, mainly distributed in the northwestern region of China. Nitraria tangut is resistant to drought, salt and alkali, wind and sand, and barrenness. It can improve saline-alkali soil, increase soil fertility, prevent wind and sand, maintain oasis, and protect ecological balance. Its berry-shaped drupe is rich in vitamin C, flavonoids, protein, 19 kinds of amino acids and 21 kinds of trace elements, and has edible value. In addition, its fruit also has medicinal value such as invigorating the spleen and stomach, lowering blood fat, lowering ...
