Quantitative analysis of the friabilin on the surface of water-washed starch granules showed that the integration of foreign puroindolines genes indeed affected the expression level of puroindolines and grain texture. 【Conclusion】In conclusion, PINA and PINB (Puroindoline) interact to form friabilin and affect wheat grain texture.
