大豆叶片异黄酮含量与PAL基因相对表达量的关系
Relationship between the Contents of Soybean Isoflavanones and Relative Expression Quantity of PAL Gene
摘要
Abstract
The phenylalanine ammonialyase( PAL) is an access point enzyme and also one of isoflavone synthesis key enzyme in the phenylalanine pathways. In order to study the relationship between the contents of soybean isoflavanones and relative expression quantity of PAL gene, a sand culture experiment was conducted. Soybean leaves at different growth stage were sampled, and the isoflavone content were measured and the relative expression quantity of alanin ammonialyase ( PAL) gene were determined by RQ- PCR. There was a coordination fluctuation tendency between phenylalanin ammonialyase ( PAL) gene relative expression quantity and isoflavone content in soybean leaf. Soybean isoflavones content and relative expression quantity of phenylalanin ammonialyase( PAL) gene appeared a peak value at Rl stage.关键词
