器官形成

During the process of long-time adaptive evolution, wetland plants adopted a series of special strategies to acclimate to salt stress. The main strategies are: 1 life history adjustment, e. g., to adjust seed germination time, implement seed dormancy and viviparity, and change reproductive manner to escape from direct salt stress, 2 morphological adjustment, e. g., to adjust biomass allocation pattern, age stem, defoliate, and carnify vegetative organs to isolate the redundant Na(superscript +) to the inactive-metabolism shoots or exclude the Na(superscript +)from tissues; 3 anatomic adjustment, e. g., to sink stoma, develop aerenchyma, and thicken cuticle and phellogen to maintain normal photosynthesis and respiration; 4 physiological and biochemical adjustment, e. g., to exclude and excrete salt, compartmentalize ions, adjust osmosis, do selective absorption, regulate hormones, and induce antioxidative enzymes to maintain the osmotic equilibrium and eliminate the active oxygen in cell; and 5 molecular level adjustment, e. g., to start up many salt-induced genes to regulate the metabolic responses to salt stress.

在长期的适应进化过程中，湿地植物形成了多种适应盐胁迫的策略，主要有：1生活史方面，植物可通过种子萌发时间的调整、种子体眠、胎生、繁殖方式的改变等逃避盐度的直接伤害；2形态学方面，植物可通过生物量分配模式的调整、茎的老化、落叶及营养器官的肉质化等将多余的Na隔离到代谢不活跃的茎中或将其排出体外；3解剖学方面，植物可通过气孔下陷、发达的通气组织、增加细胞木栓层、角质层及栅栏组织的厚度等以维持植物正常的光合作用和呼吸作用；4生理生化方面，植物可通过离子区隔化、拒盐、泌盐、选择性吸收、渗透调节、激素调节及抗氧化物酶的诱导等来维持细胞内正常的渗透压，清除胞内活性氧分子；5分子水平方面，植物可通过多种与盐胁迫相关的基因来调控细胞内的多种代谢反应。

If you will try to form a notion of yourself, of the sort of a something that you suspect to inhabit and partially to control your flesh and blood body, you will encounter a walking bundle of superfluities: and when you mentally have put aside the extraneous things — your garments and your members and your body, and your acquired habits and your appetites and your inherited traits and your prejudices, and all other appurtenances which considered separately you recognize to be no integral part of you,— there seems to remain in those pearl-colored brain-cells, wherein is your ultimate lair, very little save a faculty for receiving sensations, of which you know the larger portion to be illusory.

如若你努力形成自己的意识，形成某种你认为占据并部分控制着你血肉之躯的东西，你就会碰上一连串的累赘；而当你心里把这些身外之物——你的衣物，你的器官，甚至于你的肉身和你业已养成的习惯，你的欲望，你与生俱来的品质，种种成见以及其他所属——弃之不顾，并区别对待时，你会发觉自己不再是个整体。似乎在你最终的栖身之地——那些珍珠色的脑细胞里，只有极少数具有接收感觉的能力，而其他的大部分，要知道，是虚幻的。

Besides playing an apparently key role in wall expansion, expansins have been implicated in an increasing number of processes including cell enlargement, seed germination, root hair formation, root growth, leaf primordium initiation,leaf growth, softening of fruits, fruit abscission and growth of the pollen tube of grasses through the stigma and the style.

目前认为扩张蛋白几乎参与了植物的整个发育过程：除具有增大细胞的功能外，扩张蛋白在细胞生长、种子萌发、根毛形成、根系生长、叶原基形成、叶子生长发育、果实成熟、器官脱离，以及花粉管生长方面起着重要的作用。

Language acts as not only a tool of thinking for human beings but also influences and restricts human beings" thought. The Sapir-Whorf Hypothesis originated in German linguistics tradition. In the eighteenth century, German scholar Herder once put forth that language was the tool, the content and the style of man"s thought. German linguist Humboldt further asserted that language was the formation organ of "thought", every language consisted of a peculiar view on the world. Boas created American descriptive linguistics by emphasizing on the description of language structure.

假说发端于德国语言学传统，德国学者赫尔得在18世纪就曾提出过&语言是人类思想的工具、内容和形式&，语言学家洪堡特发展其观点，指出语言是&思想形成的器官&、&每一种语言都包含着一个独特的世界观&。20世纪初，德裔美国语言学家鲍阿斯创立以语言的外部形式特征为重点的客观描写主义，并且首次阐述了不同语言是以不同方式对经验进行分类和划分的观点，为假说形成提供了的重要论据和研究的方法论基础。
