Key Points

  • Promoting betalain levels can significantly enhance crop nutritional value and market appeal, supporting agricultural innovation.
  • The integration of eRUBY technology with TyrA arogenate dehydrogenase boosts betalain levels in rice endosperm.
  • The study employs a molecular genetic approach to assess the impacts of engineered enzymes on metabolite accumulation.
  • This advancement could benefit rice production; further exploration on real-world applications is recommended.

Abstract

eRUBY is a powerful visual reporter combining a feedback-insensitive TyrA arogenate dehydrogenase (ADHα) gene with original RUBY structure, and substantially promotes betalain biosynthesis in rice endosperm.
