This property is why it is a valued base for paints and varnishes, but this varnish is chemically closely related to the age pigment that forms "liver spots" on the skin, and similar lesions in the brain, heart, blood vessels, lenses of the eyes, etc. The image of "hard, white saturated coconut oil" isn't relevant to the oil's biological action, but the image of "sticky varnish-like easily oxidized unsaturated seed oils" is highly relevant to their toxicity.

这个属性是为什么它是一个有价值的基地，涂料，油漆，清漆，但这个是化学密切相关，年龄色素的形式"肝点"，对皮肤，和类似的病变，在脑，心，血管，镜头的眼睛等的形象，"硬，白饱和的椰子油"是不相关的石油的生物行动，但形象"粘研磨剂一样容易氧化的不饱和籽油"是高度相关的毒性。

Discussions are given of the fate of Ms2 during translocation in the hexoploid triticale, the exchange of the names for 4A and 4B chromosomes in common wheat and the possible expoitation of the new locus Ms2 (4BS), and the following speculations are made: In geneic genes of allopolyploid organisms the donor chromosomes tend to be intergenomically translocated to their phylogically and evolutionarily close chromosomes with the same order number and the same arm; it is cofirmed that the 7th International Conference of Wheat Genetics was right to exchange the names between chromosomes 4A and 4B of common wheat in 1988; and as a new genetic marker and a breeding tool for all the chromosome B-carrying species in the tribe of Tritceae, Ms2 (4BS) may have wide application in building and expanding the gene pool of germplasm resources of various species of wheat.

对 Ms2基因在六倍体小黑麦与原太谷核不育小麦远缘杂交中易位时的走向，普通小麦4A与4B染色体的互换更名以及 Ms2(4BS)新位点的开发利用进行了讨论：认为异源多倍体生物核基因的组间易位倾向于从供体染色体向进化亲缘关系较密切，且染色体序数与染色体臂相同的部分同源染色体易位；1988年第7届国际小麦遗传学会对普通小麦4A与4B染色体的互换更名是正确的； Ms2(4BS)作为一个新型的遗传标记，作为小麦族内所有携带B染色体组的物种的育种工具和在拓建各类小麦种质资源的基因库等方面均有广泛的用途。

TCM is closely related and promotes each other with Chinese traditional culture from cultural improvement;multi-science standard put forward by Polo.Sajade is defined to TCM from the angle of respecting science;TCM functions importantly to keep ecological balance and prevent land sandization from the angle of preserving multi-biology;TCM sponsors "beneficiary"for humane treatment;thus we are fully convinced to prove TCM's important social value and practical meaning.

To better understand the roles of LsrA protein in nodulation, a series of analyses of nodules using scanning electron microscopy, genetic and biochemical approaches have been carried out. Our analyses suggest that the lsrA1 nodules contain bacteroids in the invasion and establishing zone only. The lsrA gene expression is active early in the invasion zone and activated later than bacA genes. The lost of LsrA protein dramatically reduced the expression of nifA and fixK, and completely blocked the expression of the nifH gene for nitrogenase. LsrA protein functions early in the bacteroid development and it is essential for the development nitrogen fixing bacteroids.

前期的工作中，苜蓿中华根瘤菌Rm1021中90个候选LysR基因已经被定向插入突变，并筛选在自生生长时期、共生生长时期的表型，以期寻找更多在自生状态或共生固氮中有功能的LysR转录因子。1 针对前期鉴定出的共生固氮必需的lsrA基因，我们应用了一系列扫描电子显微镜技术、生物化学、分子遗传学等方法，发现lsrA基因主要在根瘤侵染区开始表达，表达时序也在侵染阶段左右，但晚于bacA基因表达；LsrA蛋白缺失后根瘤固氮区中缺乏具有固氮能力的类菌体，nifA和fixK基因的转录水平降低，nifH基因的转录被完全阻断，因此LsrA蛋白为根瘤发育所必需，是新的根瘤发育信号传导途径成员。2 通过表型筛选我们鉴定了苜蓿中华根瘤菌的oxyR基因，并研究了它的调节特性。oxyR突变后，苜蓿中华根瘤菌对过氧化氢敏感性提高，适应性降低。

His scroll has, of course, been heavily charged withpunishments: he has known the muzzle, the leash, and the tether; he has suffered theindignities of the show bench, the tin can on the tail, the ribbon in the hair, hisauthority, his digestion ruined by the macaroons and marshmallows of doting women. The list of his woes could be continued indefinitely. But he has also had his fun, for he has been privileged to live with and study at close range the only creature with reason, the most unreasonable of creatures.

它得到了项圈，当然，是经过伤痕累累才换回来的：它体验过口络、皮带和狗绳的滋味，也体会过宠物秀上跑台子、尾巴上拴铁罐和皮毛中缠丝带的味道，连它和同类异性的交往也被老大的黑手死死控制着，它的消化器官也被那些溺爱狗狗的女人用饼干和软糖给毁掉了，但是它还是有自己的乐趣：因为它是如此的有幸，才能在和这世界上唯一讲道理，也是最不讲道理的生物的一起生活中，近距离的来研究他们。
