Embodiment

[0027] Step 1, Cultivate Artemisia annua sterile vaccine

[0028] Artemisia annua seeds were soaked in 75% (v / v) ethanol for 1 min, then soaked in 20% (w / v) NaClO for 20 min, rinsed with sterile water for 3-4 times, blotted the surface moisture with sterile absorbent paper, and inoculated Cultivate on hormone-free MS solid medium at 25°C under 16h / 8h (light / dark) light (14 days) to obtain sterile vaccines of Artemisia annua.

[0029] Step 2: small amount of extraction of total DNA from Artemisia annua leaves by CTAB method

[0030] Take about 100mg of leaves into a 1.5mLEP tube, add 600μL of preheated CTAB buffer containing 2% (v / v) β-mercaptoethanol, grind the leaves with a grinding rod until there are no obvious particles; place the EP tube in The cells were fully lysed in a water bath at 65°C for 45 minutes. After the solution is cooled, add an equal volume (600 μL) of 24:1 (v / v) chloroform:isoamyl alcohol, mix well, let stand for 5 minutes, and centrifuge at 25°C and 13,...

Abstract

The invention discloses a DBR2 gene promoter in the technical field of gene engineering. The promoter has an SEQ ID NO.1 1520bp nucleotide sequence in a sequence table; and the promoter can guide the gene to specifically express in plant glandular hairs and can be applied to genetic engineering breeding for plant glandular tissue expression utilization and metabolite production. The DBR2 gene promoter can guide the gene to specifically express in plant glandular hairs and is significant to the genetic engineering breeding for plant glandular tissue expression utilization and metabolite production.

Description

technical field [0001] The invention relates to a gene promoter in the technical field of genetic engineering, in particular to a DBR2 gene promoter specifically expressed in plant glandular hairs. Background technique [0002] Artemisia annua L. is an annual herb belonging to the family Asteraceae. Artemisinin is a sesquiterpene lactone compound containing a peroxide bridge structure isolated from its aerial part. It is currently recognized as the most effective drug for treating malaria in the world, especially for cerebral malaria and chloroquine-resistant malaria. efficient. Currently, the most effective treatment for malaria recommended by the World Health Organization is artemisinin combination therapy (ACTs). In addition, with the gradual deepening of pharmacological research on artemisinin, scientists have found that artemisinin and its derivatives also have anti-inflammatory, anti-schistosomiasis, anti-tumor and immune regulation functions. It can be seen that art...
