Polymorphism in Rice Amylases at an Early Stage of Seed Germination |
|
| Abstract: | A polymorphism in rice amylases at an early stage of seed germination is analyzed by zymogram. In nonglutinous cultivars of rice, α-amylase isozymes are mainly confirmed in germinating seeds. However, in glutinous cultivars, β-amylase isozymes, which are not confirmed in nonglutinous cultivars, make up the major part of the total amylase activity and the expression of α-amylases are repressed. |
