But it is obviously under 97.0% with other groups. With further comparing the rps3 gene of ribosomal protein gene for the CWB-YN strain,the results show that these strains shared highest homology (98.1% and 100%)with Aster yellows and Periwinkle yellows.

进一步比较CWB-YN株系核糖体蛋白基因rps3基因编码的氨基酸序列同源性，结果与16S rI–B亚组的翠菊黄化病植原体(Aster yellows，AY)和长春花黄化病植原体(Periwinkle yellows，PY)的同源性最高，分别达98.1%和100%。

Positive results of mutagenicity have been obtained with chrysophanol aloe-emodin emodin and chrysarobin in Salmonella /microsome assays.

致畸作用。沙门氏菌/微粒体中的致畸结果为阳性的有：大黄酚，芦荟-大黄素，大黄素，和驱虫豆素以上均为大黄的化学成份），大黄酸的结果为阴性。

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 above results suggests that the hydrolase and FMO in microsomes are involved in the formation of M1 and M2 respectively.

黄素单氧化酶的特异性抑制剂甲巯咪唑可以显著地抑制M2的形成，但对M1的形成无明显的抑制作用，且M1在肝微粒体中的形成为NADPH非依赖性，上述结果提示参与M1和M2代谢的酶分别为肝微粒体中的水解酶和黄素单氧化酶。

Methods: Determination of total ginkgo flavones and phenol red in rats by HPLC and UV.

采用大鼠在体胃肠循环装置，以银杏总黄酮为考察指标，采用UV法和HPLC法检测总黄酮和酚红在大鼠在体胃、肠循环的含量。

The spore germination and gametophyte development of 21 ferns are studied. It indicates that :① the development period of prothallium and young sporophyte of the same species is different due to seeding time of spores;② the optimal temperatures of spores germination and gametophyte development of 21 ferns are about 15 -24 ℃;③ the rate of spore germination of rare ferns is much lower than the ferns which occur large populations in nature;④ the treatment with GA 3 can accelerate the germination of the spores;⑤ the prothallium changes from large to small, green to yellow when young sporophyte comes out. The prothalliums of all 21 ferns die away after the appear of the 3rd leaf of sporophytes;⑥ shapes of the 1st and 2nd leaves of the young sporophyte are different from those emerged later;⑦ spores cultured in dark can not germinate;⑧ a prothallium can develop only one young sporophyte though it has many archegoniums, and the spore propagation with leaf mould substrate is an economical method.

摘 要：以腐叶土为培养基质，对 21 种蕨类植物进行了孢子萌发和原叶体发育的研究，结果表明：①不同时期播种的同种蕨类的孢子，发育出原叶体和幼孢子体所历经的时间长短不同；②孢子萌发和配子体生长发育的适宜温度约为 15 ～ 24 ℃；③稀有蕨类的孢子萌发率低，而在野外能形成较大种群的蕨类的孢子萌发率高；④用 GA 3 处理孢子可以促进萌发；⑤当原叶体上长出幼孢子体时，原叶体由大变小，由绿变黄， 21 种蕨类的原叶体都在幼孢子体上长出第 3 片叶时消失；⑥幼孢子体上长出的第 1 、 2 片叶在形态上与以后长出的叶不同；⑦孢子萌发需要光；⑧ 1 片原叶体尽管有多个颈卵器，但仅发育出 1 株幼孢子体；⑨利用腐叶土进行蕨类孢子繁殖是一种经济实用的繁殖方法。

There has been the report such as the male agaric fruiting body can restrain the tumour, gallbladder fibrosis, lipide overoxidation and so on. But both here ahd abroad have no report about male agaroc mycelium amylose could decrease bllod pressure and protect liver fuction.

有关桑黄子实体多糖抗肿瘤、抗肝纤维化与抗脂质过氧化作用活性及桑黄菌丝体多糖抗肿瘤活性的研究已有报导，但国内、外有关桑黄菌丝体多糖的降血糖、保护肝功能作用等生物活性的研究至今尚未见报告。

The international nutrient value assessment method was applied to the overall assessment of the protein nutrient value of Pholiota adiposa mycelia. The assessing result showed that the total essential amino acid in Pholiota adiposa mycelia was very high, making up to about 40.0% of the total amino acids.

相对黄伞子实体的栽培而言，通过液体发酵技术生产黄伞菌丝体具有产量高、周期短、不受气候变化的影响、条件易于控制等优点，因此，对黄伞菌丝的液体发酵工艺和菌丝体的营养价值进行研究具有重要的实际意义。
