Elucidation of the potential mechanism of tannase in removing the astringency of hickory nuts and its effect on flavor profile utilizing wide-targeted metabolomics, E-nose, and HS-SPME-GC-MS.

Hickory (Carya cathayensis Sarg.) is a unique economic tree species in China, and its nuts are rich in nutrition. However, its seed coat harbors abundant astringent compounds including phenolic compounds, flavonoids, tannins, and others, necessitating their removal prior to consumption.

WRINKLED1 Positively Regulates Oil Biosynthesis in .

Hickory ( Sarg.) is a kind of important woody oil tree species, and its nut has high nutritional value. Previous gene coexpression analysis showed that WRINKLED1 (WRI1) may be a core regulator during embryo oil accumulation in hickory.
