However, chloroplast matK genes are indispensable since in nonphotosynthetic parasitic plant, Epifagus virginiana and fren, Adiantum capillus-veneris which chloroplast genome has rearrangememt, the chloroplast matK is functional even being a free-standing from with dismissed trnK exons.The chloroplasts of Psilotum, moss and liverworts all have trnK5'-matK-trnK3' structure, but it is found that matK is a pseudogene in hornwort Anthoceros formosae. Little is known in other lower land plants, it is the purpose of this thesis to examine the presence of chloroplast matK gene is these taxa.

叶绿体trnK5'-matK-trnK3'的结构在高等植物相当一致，但先前研究发现两个matK脱离trnK而存在的例子，像是叶绿体严重退化的寄生植物Epifagus virginiana及因叶绿体基因重组而导致trnK外显子丢失的铁线蕨，它们的matK仍然具有完整的开读框，显示了matK的确十分重要而不可缺失，藓苔类和松叶蕨也被证实具有trnK5'-matK-trnK3'的结构，但是在角藓中却发现其matK是伪基因。

An area having a wet, spongy, acidic substrate composed chiefly of sphagnum moss and peat in which characteristic shrubs and herbs and sometimes trees usually grow.

沼泽，湿地底面为酸性和湿软的地带，主要由灌木、草类及一些树的水藓泥沼和泥煤构成

The forest communities with this species can be divided into six groups, which are Cyclobalanopsis stewardiana-Sinarundinaria nitida community, Cyclobalanopsis stewardiana + Quercus engleriana + Carpinus viminea-Sinarundinaria nitida community, Cyclobalanopsis stewardiana-Euryia brevistyla community, Rhododendron ririei + Cyclobalanopsis multinervis-Illicium simonsii community, Fagus lucida + Cyclobalanopsis multinervis + Cyclobalanopsis stewardiana-Sinarundinaria nitida community and Cyclobalanopsis stewardiana-Camellia cuspidata-Illicium simonsii community respectively.

通过使用双向指示种分析和无偏对应分析两种方法进行研究的结果表明，梵净山树干附生尖叶拟船叶藓在群落水平上的分布与森林群落类型相对应，其所在群落可以分成贵州青冈－箭竹群落、贵州青冈＋巴东栎＋雷公鹅耳枷－箭竹群落、贵州青冈－短柱柃群落、大钟杜鹃＋多脉青冈－野八角群落、亮叶水青冈＋多脉青冈＋贵州青冈－箭竹群落和贵州青冈－尖叶山茶－野八角群落6类树附生苔藓植物群落类型。

In this study, the exon2 fragments of CHS genes in ferns, gymnosperms and angiosperms, a total of 22 fragments from 12 systematic families, were amplified successfully by PCR, and then sequenced (PCR amplification of the exon 2 from musci is in process).

本实验用PCR方法从蕨类，裸子植物和被子植物，共12个科中均成功地扩增了22个CHS基因外显子2片段（从藓类中扩增CHS基因外显子2的工作正在进行）。

It is found that (1) the aquatic protozoa communities consists of thirty-six taxa in twenty-six genera and twenty-four families;(2) the groups of ecological function include: Photosynthetic autotrophs (P groups, 25%), Bactivores detritivores (B groups, 44.44%), Saprotrophs (S groups, 2.78%), Algivores (A groups, 11.11%), Nonselective omnivores (N groups, 11.11%) and Raptors (R groups, 5.56%);(3) according to the characteristics of karst water, substrates and mosses, four ecological types and eight sub-types of aquatic protozoa communities can be distinguished.

2水生原生动物群落含6个功能营养群。其中，原生动物光合营养群（P群，Photosynthetic autotrophs），占总数的25%；细菌取食者群（B群，Bactivores detritivores），占总数的44.44%；腐生营养类群（S群，Saprotrophs，占总数的2.78%；食藻者类群（A群，Algivores），占总数的11.11%；非选择性杂食者群（N群，Nonselective omnivores），占总数的11.11%；食肉者群，占总数的5.56%。(3)根据岩溶水流、基质和藓类植物特征，划分该区附生水生原生动物生态群落为4个类型和8个亚类型。

Naturally occurring terpenes constitute the largest group of natural products with complicated and variable structures and a great number of important biological activities.2-Methyl-D-erythreitol 4-phosphate pathway is a newly found and established biosynthetic route for terpenoids and all the enzymes involved in this pathway can be used as targets for the screening of new antibiotics.

萜类化合物构成了最大的一个天然产物家族，结构复杂多变，且有许多重要的生理活性。2-甲基-D-赤藓糖醇4-磷酸途径是近年来发现并建立的一条萜类化合物的生物合成途径，其中所涉及到的酶均可作为靶标来进行新抗菌素的筛选。
