Drought response mechanism of the Tartary buckwheat (Fagopyrum tataricum) variety ‘Dingku1’: multiple regulation of flavonoid biosynthesis by FtMYBs

Puntos clave

• Flavonoid biosynthesis is significantly regulated by the FtMYBs during drought conditions, highlighting the importance of these genes.
• A total of 12 different flavonoid compounds were identified in the plant under stress, showcasing its metabolic response.
• Metabolomic analysis revealed increases in key metabolites directly linked to stress tolerance during drought.
• The findings indicate the need for further research into how these regulatory mechanisms function in other crops.
