Description

technical field

[0001] The invention belongs to the field of genetic engineering and relates to a plant promoter. In particular, it concerns a damaged, methyl jasmonate (MeJA)-inducible promoter isolated from Brassica juncea. Background technique

[0002] Because plants cannot move autonomously, they can only adapt to the environment passively. After long-term evolution, plants have established a set of protection mechanisms to resist unfavorable factors such as pests and diseases, such as forming physical barriers such as thick cell walls; and quickly start the expression of some genes to resist the attacks of diseases and pests , such as chitinase gene, protease inhibitor gene, and disease process protein gene. It has been found that hormones in plants, such as methyl jasmonate (MeJA), abscisic acid (ABA), salicylic acid (SA), etc., change significantly when pests and diseases occur. It is speculated that these hormones play a role in the process of plant resistance to p...
