一种调控马铃薯和番茄中甾体糖苷生物碱含量的转录因子BSB2及其应用
By identifying and validating the transcription factor BSB2, a transcriptional complex with GAME9 and others was formed, which synergistically regulates the synthesis of steroidal glycoside alkaloids in Solanaceae crops. This solves the problem of incomplete regulation in existing technologies and improves crop quality and safety.

AI Technical Summary
Existing technologies are insufficient to fully understand and regulate the synthesis mechanism of steroidal glycoalkaloids (SGAs) in solanaceous crops, making it impossible to precisely improve their content and limiting the improvement of crop quality and food safety.
The function of transcription factor BSB2 was identified and verified. Through gene editing technology, the synthesis of steroidal glycoside alkaloids in potatoes and tomatoes was regulated to form a transcriptional complex with transcription factors such as GAME9, which synergistically regulates the synthesis pathway of SGAs.
It provides direct molecular targets for targeted improvement of steroidal glycoside alkaloid content in Solanaceae plants, thereby increasing breeding efficiency, ensuring food quality and safety, and expanding the applicability of the regulatory mechanism.
