Regulation of grain protein content by the amino acid permease gene OsAAP4 in rice

Key Points

• Grain protein content increases with the activity of the osAAP4 gene, and its regulation is crucial for rice quality.
• The study measured protein levels and identified a significant correlation between osAAP4 expression and protein accumulation.
• Analysis of gene expression patterns showed that altering osAAP4 levels directly affects the pathways regulating protein synthesis in grains.
• Understanding these molecular pathways may lead to improved rice varieties with higher nutritional value, addressing food security.
