应用微卫星标记技术和可溶性蛋白质含量测定 ,对水稻品种粤香占及其由高压引起的变异材料粤压 1、2、3、4号进行分子生物学研究。结果表明 ,在选取的 88对微卫星引物中有 11对表现多态性 ,变异材料与原种的多态性频率介于 3 .4%～11.3 % ,多态性标记随机地分布于水稻染色体上 ,形态上与原种越相近的材料多态性位点数越少。此外 ,每一变异材料叶片可溶性蛋白质含量互不相同 ,均显著低于对照 The microsatellite markers and soluble protein content were used to study the molecular biology of Yuexiangzhan and its high pressure-induced variation material Yue pressure 1,2,3,4. The results showed that 11 out of the 88 pairs of microsatellite primers were polymorphic, the frequencies of the polymorphisms between the mutants and the original species ranged from 3.4% to 11.3%, and the polymorphic markers were randomly distributed in rice chromosomes On the morphological and the original species more similar material polymorphism less number of sites. In addition, the leaf soluble protein content of each mutant was different from that of the control
