铁线蕨

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。

All of the taxa have SC are belong to PT clade or AD clade in Pteridaceae, including Actiniopteris, Onychium, Pityrogramma, Pteris, Adiantum, and vittarioids.

重建特徵演化树的结果则显示凤尾蕨支与铁线蕨支之矽异形细胞应为不同起源，其中凤尾蕨支内的矽异形细胞亦可能为多次起源。

There were 69 species in the herb layer, where the dominant species were Miscanthus floridulus, Dicranopteris dichotoma, Lygodium japonicum, Woodwardia japonica, Ophiopogon japonicus, Lophaatherum gracile, Adiantum capillus-venevis and Cyrtococcum patens.

草本层植物有69 种，主要由蔓山莠竹、芒萁、海金砂、狗脊、土麦冬、淡竹叶、铁线蕨和弓果黍等组成。

The results of character evolution history reconstruction shows the SC in PT and AD clade might be a homoplasy character; also, the SC in PT clade might have multiple origins. SC in Pteridaceae has some special characteristics:(1) the cell long axes usually run parallel to the lateral veins;(2) Most of Pteris and Adianum species have VSC only in lower epidermis;(3) Species have ISC also have VSC.(4) Presence of spicular cells is highly correlated with the long veinal epidermal cells. Species have type III silica deposition type usually have longer and narrower veinal epidermal cell compared with ordinary epidermal cells; Species have type IV silica deposition type also have long epidermal cells, but not significantly different from ordinary epidermal cells.

本实验中亦发现凤尾蕨科之矽异形细胞具有几项特色：(1)矽异形细胞之长轴多与叶片侧脉方向平行(2)发现多数铁线蕨属以及凤尾蕨属植物仅下表皮具有脉上矽异形细胞；(3)具有脉间矽异形细胞的种类会同时具有脉上矽异形细胞；(4)长条形的侧脉上表皮细胞与矽异形细胞具有相关性，仅具脉上矽异形细胞的分类群之脉上表皮细胞均较一般表皮细胞细长；具有脉间矽异形细胞之物种之脉上表皮细胞亦为长条形但形态与一般表皮细胞常无明显形态差异。

For centuries, traditional Chinese physicians have used extracts from leaves of the maidenhair tree, Ginkgo biloba , to treat asthma, bronchitis, and brain disorders.

几个世纪以来，传统的中医师一直将铁线蕨和银杏叶等植物的提取物应用于治疗哮喘、支气管炎和大脑功能障碍等疾病。
