The results showed that the optimized content of Mg~(2+) was 5mmol/L; dNTP was 200μmol/L; Primer was 0.5μmol/L; Taq polymerase was lU/50ul in the PCR system. Only one fragment of about 270bp was amplified within the genome of 12 wild species and 23 cultivars of Mallus Mill., which indicated that Ty1-copia-like retrotransposons were archaic components of apple genome. The nested insertion of near and within the reverse transcriptase gene of Ty1-copia-like retrotransposons wasn\'t found in apple genome.2 The reverse transcriptase conservative region of Ty1-copia-like retrotransposons were amplified from Gala apple using the optimized PCR system. The amplification product was isolated, cloned and sequenced. Forty-five clones containing reverse transcriptase conservative region were obtained (accession number: AY849580 -AY849592 and DQ105035-DQ105066). Cluster analysis of these sequences showed a great heterogeneity among RT domains isolated from the same genotype.

从苹果属12个野生种和苹果23个栽培品种中都扩增到了约270bp的目的产物，且所有试材的扩增结果一致，均无目的条带以外的产物扩增，说明Ty1-copia类逆转座子在苹果属植物中广泛存在，且存在历史可能较为久远；从扩增结果看不出该逆转座子的逆转录酶基因或附近区域在苹果基因组内有嵌套行为的发生。2、利用优化了的PCR方法从嘎拉苹果基因组克隆了45条Ty1-copia类逆转座子逆转录酶保守序列(登陆号分别为AY849580-AY849592和DQ105035-DQ105066)，结果表明，同一基因组来源的这些序列存在高度的异质性。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
