By analyzing the N-terminal amino acid sequence and searching in NCBI database, we found SBP117 is a member of proline-rich protein family and its function is unknown. The registered number is AAO72557.1. The composition of amino acids of this protein is similar with those proteins found in diatom and cucumber, but the sequence of amino acids is different. It means that SBPl 17 is a special protein for graminaceous plants to control the silica deposition.

通过N-末端测序和查询NCBI数据库，鉴定了SBP117是一种未知功能的富脯氨酸蛋白家族的成员，其蛋白质序列号为AAO72557.1，它的氨基酸组成与硅藻和黄瓜中发现的硅结合蛋白相似，但排列顺序明显不同，说明其可能是一种禾本科植物所特有的控制硅沉积代谢的蛋白。

At the experimental concentrations tested (00 u.g I/1), selenite and selenate did not significantly affect the accumulation of either mercury species by the green mussels. In contrast, selenomethionine significantly inhibited the uptake of MeHg and enhanced the uptake of Hgy the mussels, but it did not affect the assimilation from the ingested diatoms. We further examined the influence of tissue body burden of Se in the green mussels following pre-exposure to selenite and selenomethionine on the accumulation of Hg2 and MeHg from the dietary and aqueous phases.

实验结果表明，在实验设定的浓度范围内(00滩。L-l)，同时暴露，s犷和s产均不能显著影响翡翠贻贝刘榕解态和颗粒态H广和MeHg的累积。seMe育游显著抑制翡翠贻贝对溶解态MeHg的吸收，提高对溶解态H犷+的吸收，但不能影响翡翠贻贝对颗粒态Hg的同化效率；通过投喂载反少或女N贻的硅藻，对翡翠贻贝进行预暴露，组织Se的浓度随预暴露时间延长而增加。

Based on the molecular mechanisms guiding the biosilicification in marine organisms such as diatoms and sponges, cell wall template-mediated self assembly of nanostructured silica in plants and related morphogenesis, structures and functions of phytogenic silica are discussed. Understanding the templating and organic-inorganic bicomponent cooperation effects not only offers the clue for constructing silicon-based structures, but also recognizes the anomaly of silicon in plant biology, esp. in stress physiology.

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。
