发布时间：2021-04-03 00:08

　　Aromatic rice belongs to a small but important sub-group of rice, which is highly regarded for its excellent aroma and superior grain quality. Aromatic rice, especially Basmati-and Jasmine-type rice, is being traded at a high price in the local and global markets. Genetically, rice aroma is a phenotypical expression of spontaneous recessive mutations of the OsBadh2 gene（also known as fgr/badh2/osbadh2/os2AP gene）. These mutations inhibit the flow of γ-aminobutyraldehyde（GAB-ald） to γ-aminobutyri...
