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。

However, yet the male agaric fruiting body is difficult to plant, but its mycelium could be planted on the artificial culture medium, and this myvelium does not have any request to the culture medium ,the mycelium grows vigorously on the culture medium.

ADVANCES OF STUDIES ON BACTEROID REPRODUCTION OF R trifolii Rhizobium leguminosarum , AND FAST GROWING SOYBEAN RHIZOBIUM

三叶草，豌豆和快生型大豆根瘤菌类菌体繁殖研究的进展

Parasitizing specially in the cytoplasma of small granular hemocytes, RLOs formed an inclusion body in host cell, in which, RLOs propagated in mass and caused the host cell swelling and disorganizing, subsequently released and infected other target histocytes, resulted in the arising of such symptoms as debility and shivering of limbs, etc..

RLOs专一性寄生于小颗粒细胞的胞质内，以包涵体的形式生长繁殖，随着RLOs的快速增殖，包涵体内RLOs数目显著增多，且多呈圆形，包涵体极度膨胀，将细胞核压向周边，最终细胞被胀破，释放出RLOs再去侵染其它组织和器官，造成颤抖、肌无力等全身症状。

Its main features are: algae body as a single cell or even into a variety of groups; cell walls composed of silica and pectin, but also by the structure of the shell and the shell under the combined set of the Cheng, vertical section view was "soap-box"-shaped; in the upper and lower shell surface of the shell are patterns arranged in patterns on both sides of the main mode of symmetry and radial symmetry is divided into two categories, for the classification of the most important basis; be able to campaign Type in the shell has a shell side seam, can not be changed no shell seam types; pigment body sheet or ribbon, 1 or 2, or for multiple small discoid, yellow green or brown, containing chlorophyll a, c, also contains fucoxanthin and silicon A flavin and other photosynthetic pigments; storage material mainly for oil droplets; reproduction mainly for cell division and cell division in diatoms obvious features are: each cell division, resulting from two sub-cells,, only one and the mother cell and so big, the other one is smaller.

其主要特征是：藻体为单细胞或连成各式群体；细胞壁由硅质和果胶质组成，而且在结构上都是由上壳和下壳套合而成，纵断面观呈&肥皂盒&形；在上下壳的壳面上有花纹，花纹排列的方式主要分为两侧对称和辐射对称两大类，为分类上的最重要依据；能运动的种类在壳面都有壳缝，不能动的种类均无壳缝；色素体片状或带状，1个或2个，或为多个小盘状，黄绿色或黄褐色，含叶绿素a、c，还含有墨角藻黄素和硅甲黄素等光合色素；贮藏物质主要为油滴；繁殖方式主要为细胞分裂，硅藻的细胞分裂的明显特点是：每次细胞分裂所产生的2个子细胞中，仅有1个和母细胞等大，另1个则稍小。

The numerous macro-plants during the Doushantuoian were branching and semi-floated and erected on seafloor. They advanced the photosynthetic efficiency and increase oxygen in water to improve in environment for metazoans; and they served as a primary producer in the paleoecosystem to provide an alternative and new food of metazoan.

陡山沱期的宏体藻类多分枝并直立固着于海底，提高了光合作用的效率，增加了海中水体中的含氧量，不仅改善了环境，为依赖一定氧而生活、生长和繁殖的后生动物给予了必要的支持，而且作为生态系统中的必要基础，为宏体后生动物的快速发展和演化提供了一个新的食物源。

The genetic study suggested that the carbendazim-resistance in these mutants could be steadily inherited by asexual and selfed reproduction, and the resistance was controlled by the same single major gene both in laboratory mutants and field resistant isolates, the different levels of resistance or the same resistant level in different strains maybe conferred by mutations at different sites or one site with different allelic mutations. The gene compensates for the sensitivity to MDPC was allelic to that governs the carbendazim resistance, but the mutation for increasing sensitivity to MDPC in this gene could get the pathogen highly resistant to carbendazim.

抗药性遗传研究表明，在所研究的抗药突变体中，抗药性在自交和无性繁殖后代中能稳定遗传；室內抗药突变体和田间抗药菌株对多菌灵的抗药性由同一个主效基因控制，但它们发生突变的位点不同或者同一碱基位点发生了不同的突变；对MDPC的敏感性也是由单个基因控制的，该基因与控制多菌灵抗性的基因是等位基因，当该基因发生对MDPC的敏感性增加的突变时会使病菌对多菌灵产生高水平抗性。
