AI Technical Summary

⚠Technical Problem

Existing cassava varieties have low levels of branched-chain amino acids, which affects their nutritional value as livestock and poultry feed. Furthermore, the amino acid synthesis mechanism is not clear, leading to a shortage of high-protein and amino acid-rich feeds.

⚗Method used

Overexpression of the MeBCAT1 gene in cassava, followed by construction of a recombinant vector and transformation of the host bacteria, increased the content of branched-chain amino acids and other amino acids, including valine, isoleucine, and leucine.

🎯Benefits of technology

It significantly increased the content of branched-chain amino acids and other amino acids in cassava leaves, enhancing their nutritional value as livestock and poultry feed and providing a new approach for cultivating new cassava varieties with high amino acid content.

Abstract

The application belongs to the technical field of biology and particularly relates to a cassava gene and application thereof. MeBCAT1 The application clones a cassava gene from cassava, overexpresses the gene in cassava, and can improve the content of branched-chain amino acids, valine, isoleucine and leucine in the transgenic cassava. MeBCAT1 In addition to improving the content of branched-chain amino acids, the gene can also improve the content of amino acids such as proline, lysine and glutamic acid in cassava. MeBCAT1 The experimental results provide a new way for improving the forage value of cassava and provide a new candidate gene for cultivating cassava varieties with excellent quality by using molecular means, which has great significance in cultivating new cassava varieties and breeding excellent cassava varieties.
