Information
- Symbol: GSA1
- MSU: LOC_Os03g55040
- RAPdb: Os03g0757500
Publication
- UDP-glucosyltransferase regulates grain size and abiotic stress tolerance associated with metabolic flux redirection in rice, 2020, Nature Communications.
Genbank accession number
Key message
- GSA1 regulates grain size by modulating cell proliferation and expansion, which are regulated by flavonoid-mediated auxin levels and related gene expression
- GSA1 overexpression results in larger grains and enhanced abiotic stress tolerance
- GSA1 is required for the redirection of metabolic flux from lignin biosynthesis to flavonoid biosynthesis under abiotic stress and the accumulation of flavonoid glycosides, which protect rice against abiotic stress
- GSA1 encodes a UDP-glucosyltransferase, which exhibits glucosyltransferase activity toward flavonoids and monolignols
