We determined the mitochondrial DNA sequence of S. yangtsekiense and discussed the phylogenetic status of freshwater crabs in Brachyuran according to gene arrangement features and sequence data sets. We also sequenced regions of mitochondrial COI and ND5 genes in order to address the genetic structure of S.

本文以长江华溪蟹为代表，通过对线粒体基因组序列的测定，从基因序列和排列顺序2个方面探讨淡水蟹类在短尾类中的系统地位；并利用COI和ND5 基因的部分序列数据，对我国长江华溪蟹种群的遗传结构进行了初步研究。

PmMYB is a typical R2, R3-MYB transcription factor with its 2 typical DNA-binding domains (amino acid sites of 13-63 and 66-114).The multiple alignment of R2, R3 amino acid repeat regions of MYB genes among broomcorn millet, rice, corn, loblolly pine, Arabidopsis, capsicum, upland cotton, barley and aubergine indicates that R2, R3 repeat regions are very conserved. The phylogenetic analysis based on amino acid sequence shows that MYB genes are highly divergent with similarity ranging from 32% to 84%.

对其与水稻、玉米、火炬松、拟南芥、辣椒、陆地棉、大麦及茄子等9种植物的 MYB 基因的R2、R3重复区的氨基酸序列多重比较，表明R2R3重复序列在植物中具有较高的保守性；基于氨基酸序列的编码区系统进化树分析表明，不同植物的MYB基因遗传分化很大，序列相似性为32%~84%，其中糜子 MYB 基因与水稻的 MYB18相似程度最高(84%)，与大麦和玉米的相似性分别为46%和41%。

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。
