A Preliminary Analysis of Phylogenetic Relationships in Cymbidium (orchidaceae) Based on nrITS Sequence Data

引用

Acta Botanica Sinica 2002年第5期44卷 588-592页

作者：张明永孙彩云郝刚叶秀粦梁承邺朱光华中国科学院华南植物研究所广州510650 密苏里植物园

The infrageneric classification currently in use for Cymbidium is based on gross morphology, with emphasis on the number of pollinia and state of fusion between lip and column. The sequences of nrDNA regions of 27 species and 3 cultivars of Cymbidium and 3 outgroup species ( Eulophia graminea, Geodorum densiflorum, Amitostigma pinguiculum) were analyzed using PCR amplification and direct DNA sequencing. The phylogenetic trees generated from maximum parsimony analysis, however, show that the existing division among three subgenera (subgen. Cymbidium , subgen. Cyperorchis and subgen. Jensoa ) should be evaluated with more data. Subgenus Cyperorchis was not a monophyletic group, with the unexpected nesting of C. dayanum (subgen. Cymbidium ) within it; subgenus Jensoa also appeared paraphyletic, with C. lancifolium being the sister group to the remainder of the genus; species of subgen. Cymbidium appeared polyphyletic, being split into several clades and intermixed with the main subgen. Cyperorchis and subgen. Jensoa clades, respectively. However, because of the insufficiency of informative characters of ITS sequences, some of the clades identified, especially the major lineages of Cymbidium , received relatively low support; sectional delimitations were also not clear within each subgenus. Further study is needed for achieving a robust phylogeny of Cymbidium .

The underground organ microbial complexes of moorland spotted orchid <i>Dactylorhiza maculata</i>(L.) Soó(orchidaceae)

引用

Advances in Bioscience and Biotechnology 2013年第7期4卷 35-42页

作者： Nina V. Shekhovtsova Oleg A. Marakaev Kseniya A. Pervushina George A. Osipov Academician Yu. Isakov Research Group Bakulev Scientific Center of Cardiovascular Surgery Moscow Russia Demidov Yaroslavl State University Yaroslavl Russia

This paper is focused on the first study of microbiota of a moderate climate orchid from Northern hemisphere—Moorland Spotted Orchid Dactylorhiza maculata (L.) Soó growing in its natural habitat. There have been obtained detailed data concerning bacterial communities from rhizosphere and inner tissues of young and old tubers. It was done using the biomarker analysis method where the markers were detected by gas chromatography—mass-spectrometry. It is shown that the number of bacterial genera and the bacteria amount (105 - 108 CFU per gram of dry weight) in D. maculata microbial complexes decreases from rhizosphere to old tuber to young. At the same time all three bacterial cenoses closely resemble each other in biodiversity. Their constant members are gg. Hyphomicrobium, Methylococcus, Nitrobacter, Pseudomonas and Sphingomonas (Proteobacteria), Bacillus and Clostridium (Firmicutes), Rhodococcus and Streptomyces (Actinobacteria). There were found differences peculiar to the taxonomic structure of each microbial complex. The rhizosphere is dominated by Actinobacteria while in inner tissues Proteobacteria are prevalent. The bacteria of gg. Ochrobactrum, Xanthomonas, Butyrivibrio, Corynebacterium, Mycobacterium, Propionibacterium, Sphingobacterium and specific iron reducers were shown to belong to rhizosphere community. Genera of Agrobacterium and Bifidobacterium were found only in the endophytic microbiota of the young tuber while g. Aeromonas
