Abstract

The invention relats to rice hpfr gene, expression products and application thereof, belongs to biotechnology field for curepreventing plant diseases and insect pests and accelerating growthing and improving crop producibility. The invention is rice hpfr gene, which first discovering gene sequence with like function that of plant pathogenic bacteria hpfr gene in plant, coding product has exciton function and generating allergic reaction on tobacco plant, inducing palnt to generate disease resistance, accelerating vegetation and improving crop producibility, for the hpfr gene steming from plant, expression product hpfr protein can be generated by efficient expression carrier and microbe fermentation, which is a economical and environmental protection biological pesticide used in plowland and for curepreventing plant diseases and insect pests and improving crop producibility. The invention also provides wheat hpfw gene whose expression pfoduct hpfw protein having function of generating allergic reaction on tobacco plant, inducing palnt to generate disease resistance, accelerating vegetation.

Description

1. Technical field

[0001] The invention relates to rice hpfr gene, expression product and application thereof, belongs to the field of agricultural biotechnology, and is used for preventing and treating plant diseases and insect pests, promoting plant growth and increasing crop yield. 2. Background technology

[0002] The hrp gene is a gene in plant pathogenic bacteria that determines the hypersensitive response (hypersensitive response, HR) on non-host plants and pathogenicity on host plants [Lindgren P B, The role of hrp genes during plant-bacterial interaction.Annu Rev Phytopathol, 1997 , 35: 129-152]. Anaphylaxis is a localized and rapid form of programmed cell death (PCD) produced by plants. PCD can trigger one or more signal transduction pathways, endowing plants with various environmental stress resistance capabilities.

[0003] The hrp gene of plant pathogenic bacteria has been studied in detail at home and abroad. Wei et al. first discovered that a new protein en...
