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.
