Discussion

Genome-wide association study highlights candidate genes linked to anthocyanin under UVB exposure in black rice.

Distinct associations for anthocyanin content under UV and non-UV conditions were revealed through GWAS.
Three candidate genes, including OsBBX14 and OsMYB44, were identified as significant for anthocyanin biosynthesis.
Research utilized a diversity panel of 191 black rice accessions and 31,501 SNPs to elucidate QTLs.
Findings have implications for developing black rice varieties with enhanced nutritional value and UV resilience.

Nguyen et al. (2025) studied this question.
