Problems solved by technology

However, at present, the research on the EREBP subfamily of the AP2 gene is relatively thorough, including structure, binding sites, and participation. In comparison, there are relatively few studies on the role of the AP2 subfamily genes in plant flower development, and the research depth is not enough

Embodiment 1

[0023] Example 1: Acquisition of peanut growth and development gene Ah56

[0024] 1. Extraction of total RNA from peanut tissue

[0025] Experimental preparation: All utensils used need special treatment. High-temperature-resistant instruments and utensils were baked at 200°C for 8 hours, and other utensils were soaked in 0.1% DEPC for 12 hours, and then removed by autoclaving to remove DEPC. The solution reagents are treated with 0.1% DEPC (sterilized after 12 hours at 37°C), and the reagents that are not resistant to high temperature are directly treated with DEPC-H 2 O preparation. Total RNA was extracted according to the operation requirements of GIBCOL's Trizol Reagent, and the specific steps were as follows:

[0026] 1) Take the young peanut leaves and grind them into powder in liquid nitrogen, then add 1 ml of Trizol solution for every 50 mg of tissue to grind, and note that the total volume of the sample should not exceed 10% of the volume of the Trizol used.

Embodiment 2

[0071] Example 2: A method for detecting the function of peanut growth and development gene Ah56 using fluorescent quantitative PCR technology

[0072] Follow the steps below to check:

[0073] Total RNA extraction and cDNA synthesis

[0074] Extract the total RNA of peanut leaves, with reference to the test method in Example 1, reverse transcription process:

[0075]

[0076] The system was placed at 37°C for 15 minutes, and the cDNA product was stored at -20°C.

[0077] Drawing of standard curve

[0078] Design a pair of PCR primers according to the cloned gene fragment: Ah56f-4 and Ah56r-4, extract the total RNA of peanut seed coat, reverse transcribe it into cDNA, use it as a template, carry out PCR amplification, recover the amplified product, and convert the PCR product Connect with pMD-18, then transform Escherichia coli DH5α, after colony PCR identification, a large number of positive clones are amplified, the plasmid is extracted, the obtained plasmid is dil...

Embodiment 3

[0089] Example 3: A method for detecting the specific expression of peanut growth and development gene Ah56 by using fluorescent quantitative PCR technology

[0090] In order to detect the specific differential expression of peanut growth and development gene Ah56, two varieties, Zhongkai 111 and Zhonghua 4, were selected and carried out in a constant temperature culture room. After soaking the seeds of the above varieties in tap water overnight, they were planted in plastic pots of the same size, two in each pot, and the cultivation carrier was common soil, and 10 pots of each variety were sown. For normal culture, samples were taken at different growth stages of peanuts, and the sampling parts were roots, stems, and leaves, which were stored in a -80°C refrigerator after being treated with liquid nitrogen. Total RNA was extracted from peanut seed coat and reverse transcribed into cDNA. (method is with embodiment 1 and 2).

[0091] Adopt the detection method described in th...

Abstract

The invention specifically relates to a peanut development gene Ah56. The gene Ah56 participates in a certain response reaction during the period in which peanut transits from a seedling stage to a flowering stage and plays a critical role in development of peanuts. Furthermore, the invention also discloses application of the gene and a method of detecting the expression level of the gene by using fluorescent quantitative PCR.

Description

technical field [0001] The invention relates to the field of agricultural biotechnology, in particular to a peanut development gene Ah56. The invention also relates to the use of the peanut development gene and a method for detecting the expression of the gene by fluorescent quantitative PCR. Background technique [0002] Peanut is the main oil crop and economic crop in my country, and it is the most competitive export-earning agricultural product in China. It is mainly distributed in subtropical arid and semi-arid areas. Peanuts experience a variety of abiotic stresses during their growth and development, such as drought, high salinity, and extreme temperature. When the peanut senses the stress signal, it will finally start the expression of related genes through a series of signal transduction to help the peanut adapt to or resist adversity. Switch genes refer to their encoded products, including transcription factors for signal transmission and regulation of gene express...
