Problems solved by technology

For example, the researchers found that in red clover (Trifolium pratense) leaves, the expression of UBC2 and UBQ10 is the most stable; in the stem, the expression of UBC2 and YLS8 is relatively stable; in the root, the expression of EIF-4a and UBC2 is stable; and in various tissues In , the stability of GAPDH and SAND is low
In addition, traditional housekeeping genes such as Actin, ubiquitin, 18S rRNA, EF1α, TUB, and TUA have been applied to poplar real-time fluorescent quantitative PCR analysis, however, these genes still have many shortcomings in terms of systematic screening (Pettengill et al., 2012)

Embodiment 1

[0022] 1. Material

[0023] The methods used in this embodiment are conventional methods known to those skilled in the art unless otherwise specified, and the reagents and other materials used, unless otherwise specified, are all commercially available products.

[0024] 2. Method

[0025] 2.1 Screening of internal reference genes

[0026] 2.1.1 Collect gene chips related to poplar stress resistance gene expression, select the gene chips numbered GSE13990, GSE15242, GSE21171 and GSE23637 as specific screening chips; the gene chip data of GSE13990, GSE15242, GSE21171 and GSE23637 are from https: / / www .ncbi.nlm.nih.gov / gds / ? term = directly downloaded from the website.

[0027] 2.1.2 Use the normalized gene chip data processing software ExpressionConsle developed by Ang Fei Company to normalize the probes contained in the 4 gene chips. The steps include:

[0028] Step 1: Use the MAS5 algorithm that comes with Expression Consle software to calculate the P-Value of each probe in the gene c...

Abstract

The invention discloses a reference gene related to stress resistance gene expression regulation of populus trichocarpa and application thereof. The reference gene has a nucleotide sequence as shown in SEQ ID NO.1 which is shown in the description. Compared with a house-keeping gene of the populus trichocarpa, the reference gene disclosed by the invention has higher stability under abiotic stress, is more ideal and is related to the stress resistance gene expression regulation of the populus trichocarpa; the reference gene has an important significance in research on the expression level of the stress resistance gene of the populus trichocarpa and systematic stress resistance research on the populus trichocarpa, and has an important guiding function for further breeding high-quality stress-resisting plants.

Description

Technical field [0001] The invention relates to the technical field of genetic engineering, in particular to an internal reference gene related to poplar stress resistance gene expression regulation and its application. Background technique [0002] Poplar (Populus trichocarpa) is an important greening energy tree species, and vigorously developing the poplar industry is of great benefit to the abundance of forest resources and the improvement of the natural ecological environment. Poplars in my country are mainly distributed in arid and semi-arid regions such as North China and Northwest China. Drought will not only affect the photosynthetic rate of leaves, the growth rate of branches and the accumulation of dry matter, but also reduce the weight and volume of poplars, thus restricting the growth of poplars. Fast-growing and high-yield. Drought is often related to osmotic stress caused by high salinity, which affects the growth and yield of poplar trees. As an important woody m...
