Abstract

The invention relates a chrysanthemum drought-tolerant related gene OtMYB, and simultaneously relates to application of the OtMYB gene in improving chrysanthemum drought-tolerant capability. The chrysanthemum drought-tolerant gene has a nucleotide sequence shown in SEQ ID No.1. The gene has a DNA bond zone of two typical MYB transcription factors, belonging to a typical R2R3-MYB transcription factor. The OtMYB is related to the chrysanthemum drought tolerance, and the gene is transcribed to a common chrysanthemum variety through genetic transformation, so that the resistance of the chrysanthemum variety on drought stress can be effectively improved.

Description

Technical field

[0001] The invention belongs to the field of plant genetic engineering, and specifically relates to a chrysanthemum drought-resistance related gene OtMYB, and at the same time relates to the application of the OtMYB gene in improving the chrysanthemum drought resistance ability. Background technique

[0002] Taihang chrysanthemum (Opisthopappus taihangensis) is a plant of the genus Taihang chrysanthemum in the Compositae family. It is distributed in Hebei, Shanxi and other places in my country. It mostly grows on hillsides and cliff rocks at an altitude of 1,000m. It is a unique plant of the general chrysanthemum with high drought resistance in China And resistant species, and has a strong ornamental. Researching the stress resistance molecular pathways of Taihang chrysanthemum and discovering important stress resistance genes will lay a good theoretical foundation for the stress resistance genetic engineering of Chrysanthemum plants and provide excellent drought r...
