Is the insertion of frost resistant genes from Bacillus thuringiensis to boast plant resistance to insect pests a green or blue biotechnology?

The insertion of frost-resistant genes from Bacillus thuringiensis to boost plant resistance to insect pests falls under green biotechnology. Green biotechnology involves the use of biological systems and organisms to improve plants, animals, and microorganisms for specific agricultural purposes, such as pest resistance. Blue biotechnology typically involves the use of marine resources for various applications, which is not applicable in this case.
