AI Technical Summary
Technical Problem
The low root biomass and natural rubber content of rubber grass limit its industrial application as a substitute for natural rubber.
Method used
By overexpressing the LTP1 gene in rubber grass to increase the content or activity of LTP1 protein, genetic modification can be carried out using nucleic acid molecules and expression vectors to enhance the root biomass and natural rubber content of rubber grass.
Benefits of technology
It significantly increases the diameter of the taproot and the weight of the dry root of rubber grass, improves the natural rubber content in the roots, and enhances the natural rubber yield of rubber grass.
