abstract = {Enhancing the dietary properties of rice is crucial to
contribute to alleviating hidden hunger and non-communicable
diseases in rice-consuming countries. Germination is a
bioprocessing approach to increase the bioavailability of
nutrients in rice. However, there is a scarce information on
how germination impacts the overall nutritional profile of
pigmented rice sprouts (PRS). Herein, we demonstrated that
germination resulted to increase levels of certain dietary
compounds, such as free phenolics and micronutrients (Ca,
Na, Fe, Zn, riboflavin, and biotin). Metabolomic analysis
revealed the preferential accumulation of dipeptides, GABA,
and flavonoids in the germination process. Genome-wide
association studies of the PRS suggested the activation of
specific genes such as CHS1 and UGT genes responsible for
increasing certain flavonoid compounds. Haplotype analyses
showed a significant difference (P < 0.05) between
alleles associated with these genes. Genetic markers
associated with these flavonoids were incorporated into the
random forest model, improving the accuracy of prediction of
multi-nutritional properties from $89.7\%$ to $97.7\%.$
Deploying this knowledge to breed rice with
multi-nutritional properties will be timely to address
double burden nutritional challenges},
