Embodiment 1

[0021] 1. Acquisition and cloning of ZmWRKY50 gene sequence

[0022] In the maizesequence database, the cDNA and protein sequences of the ZmWRKY50 gene were obtained.

[0023] The cDNA sequence of ZmWRKY50 gene was analyzed, and the primer W50F / R was designed. W50F: tatctagagacaaacacctcccaaccc; W50R: atgagctcctccctctttctacaaccttcttc;

[0024] Using the cDNA of maize inbred line 178 as a template, the ZmWRKY50 gene was specifically amplified.

[0025] The reaction system is:

[0026] Table 1 PCR reaction system

[0027]

[0028] The PCR reaction program is: 95°C for 3min; 95°C for 30sec, 60°C for 30sec, 72°C for 1.5min and 35cycles; 72°C for 5min. The PCR product was detected by 1.0% agarose gel electrophoresis, and the target band was recovered using the agarose gel recovery kit of Omega Company.

[0029] Amplification of the ZmWRKY50 gene

[0030] Use the specific primer W50F / R of ZmWRKY50 to amplify the cDNA of these two genes from maize inbred line 178, obtained th...

Abstract

The invention relates to the field of plant stress resistance, and particularly relates to an application of a ZmWRKY50 gene in improving the acid aluminum resistance of a plant. The result of RT-qPCR detection proves that the expression of the ZmWRKY50 gene experiences different degrees of induction and inhibition of AlCl3. Along with the continuously increasing AlCl3 concentration, the expression of the ZmWRKY50 gene is increased and then decreased. When the AlCl3 concentration is excessively high, severe toxic action is generated on the plant, and the expression of the ZmWRKY50 gene is correspondingly inhibited, thereby indicating that the expression of the ZmWRKY50 gene is induced in a proper range of AlCl3 concentration; and the acid aluminum stress on the plant is subjected to positive control so as to improve the acid aluminum resistance of the plant.

Description

technical field [0001] The invention relates to the field of plant stress resistance, in particular to the application of the ZmWRKY50 gene to improve the aluminum tolerance of plants. Background technique [0002] As an important food, feed and economic ternary crop in my country, corn is affected by various adverse external environments such as pests, drought, salt damage, cold damage, and high temperature during its growth, thereby inhibiting its growth and development. Applying modern molecular biology techniques to excavate important stress-resistant genes and carry out genetic transformation or aggregate them with other excellent traits through molecular marker-assisted selection is one of the effective methods to obtain maize varieties with strong stress tolerance and improve maize yield. one. Functional research on stress-related genes is a prerequisite for the development and utilization of these genes. WRKY transcription factors play an important regulatory role ...
