The biosynthesis of anthocyanins is still questionable in regulating the quantities of anthocyanins biosynthesized in rice seeds and the expression levels of transcription factors and the structural genes involved in the biosynthetic pathway of anthocyanins. We herein investigated the relationship between the accumulated anthocyanin contents and the expression levels of genes related to the biosynthesis of anthocyanins in rice seeds. Liquid chromatography/mass spectrometry-mass spectrometry analysis of cyanidin 3-glucoside (C3G) in rice seeds showed no accumulation of C3G in white and red rice cultivars, and the differential accumulation of C3G among black rice cultivars.

- * Analysis using ultra-performance liquid chromatography showed that I.526 had significantly higher levels of resveratrol and piceid compared to I.515, with peak concentrations occurring at different stages post-heading.
- * RNA sequencing and quantitative PCR revealed distinct differences in the expression of genes related to piceid and resveratrol biosynthesis between the genetically modified rice lines and their parent cultivar, indicating that the AhRS3 transgene impacts gene expression patterns in developing seeds.
