Abstract excerpt
D-amino acids are key components of the bacterial cell wall and play important roles in neural communication and inflammatory responses in animals. However, knowledge about D-amino acid metabolism and physiological functions in plants is limited. Here, we isolated and characterized a rice D-amino acid aminotransferase1, OsDAAT1, which maternally regulates rice grain chalkiness through map-based cloning and a...
