查询词典 polymorphism

Methods 202 kinless subjects of the Chinese Han were investigated in this study, including 82 normal controls, and 120 cases diagnosed as CHD. The PPARδ+294T/C gene polymorphism was determined by polymerase chain reaction and restriction fragment length polymorphisms. The frequencies of PPARδ+294T/C genotypes and the "C"allele frequency were analyzed, to evaluate the risk for the CHD among variant genotypes.

In this context the wild mango germplasm at Lapuo County, Guangxi, China were studied by using their biological characteristics and the amplified fragments length polymorphism molecular marker. These wild mangoes were found morphologically similar to Mangifera indica; and the AFLP markers showed that at the similarity coefficient of 0.63, 92 mangoes including cultivars, Mangifera sylvatica Roxb., wild mangoes, Mangifera. Siamensis Warbg. were divided into 14 groups and that the wild mangoes at Lapuo were close to M. sylvatica Roxb. and M. siamensis Warbg., but remained to fall in the middle of the cultivars and could not be separated from them.

结果表明：那坡县野生芒果在形态学上与普通芒果较为相似；AFLP标记显示，包括部分栽培品种、林生芒果、广西百色那坡县野生芒果、泰国芒果等在内的92份芒果种质在相似系数0.63的水平上可分为14组，广西百色那坡县野生芒果虽然与林生芒果、泰国野生芒果等芒果属其它种较为接近，但仍处于栽培芒果的中间，不能与栽培芒果分开。
