[Advances in the application research of bacterial ice nucleation active (ina) genes].

For recent years, the research has been focused on the ina gene application in the field of biological ice nucleation. This paper reviewed the application of ina genes in bacterial cell surface display, construction of reporter gene systems, killing insect pests through induced freezing, sensitive detection of pathogenic bacteria contaminating foods, breeding of cold resistant varieties. A brief introduction of the ina gene application in killing insect pests in China was also made in this review.
