Surprise new orchid revealed

چکیده

What is your greatest research ambition? I would like to contribute to improving the integration of understanding of the functioning of organisms, and of their interactions with the environment across large ranges of time and space. This would help in making post-genomic information more relevant to investigating environmental issues, and suggesting to those working at the molecular-to-cellular levels the most appropriate ways to address problems in Earth Systems Science. Life has survived many rapid and large amplitude environmental changes over billions of years, but we should not be complacent about the biological effects of current anthropogenic influences on the environment. At the most selfish level, we depend on the continued provision of 'ecosystem services' for our quality of life. Orchids are very well recorded in countries with many experts, so the confirmation of a new species in Britain has been met with delight. A new book, Britain's Orchids, by David Lang, describing the 50 or so native species in the country, includes a listing for the Lindisfarne helleborine (Epipactis sancta) which grows only in a patch of sand dunes on Holy Island, off the coast of northeast England. These orchids were thought to members of the dune orchid (Epipactis dunensis) species, but minor morphological differences had hinted at something unusual in this isolated population. New DNA studies confirm that the Lindisfarne helleborine is sufficiently distinct from the dune helleborine to deserve the new species name and many enthusiasts have been flocking to see the tiny population of around 270 specimens this summer.

Complete Citation: Dearnaley, John and Le Brocque, Andrew F. (2006). Molecular identification of the primary root fungal endophytes of Dipodium hamiltonianum

We have identified the primary root fungal endophytes of Dipodium hamiltonianum F.M. Bailey, a species of orchid endangered in Victoria and uncommon in New South Wales and Queensland. Genomic DNA was extracted from whole colonised root portions from four orchid individuals and PCR amplified with ITS1F and ITS4 primers. Cloning and sequencing of the main amplicons produced from the PCR analysis ...

The Effects of Hydro-alcoholic Extracts of Allium sativum L. and Orchismaculata L. on Spermatogenesis Index and Testosterone Level in Cyclophosphamide-treated Rats

Background:One of the most common side effects of cyclophosphamide (CP) is oligo-spermatozoa, azoospermia and elimination of spermatogenic cycles. This study was done to find the efficacy of simultaneous consumption of garlic (Allium sativum L.) and orchid (Orchismaculata L.) hydroalcoholic extracts on spermatogenesis and sex hormones in rats treated with CP. ...

A New Orchid Genus, Danxiaorchis, and Phylogenetic Analysis of the Tribe Calypsoeae

BACKGROUND Orchids have numerous species, and their speciation rates are presumed to be exceptionally high, suggesting that orchids are continuously and actively evolving. The wide diversity of orchids has attracted the interest of evolutionary biologists. In this study, a new orchid was discovered on Danxia Mountain in Guangdong, China. However, the phylogenetic clarification of this new orchi...

A Modified ABCDE Model of Flowering in Orchids Based on Gene Expression Profiling Studies of the Moth Orchid Phalaenopsis aphrodite

Previously we developed genomic resources for orchids, including transcriptomic analyses using next-generation sequencing techniques and construction of a web-based orchid genomic database. Here, we report a modified molecular model of flower development in the Orchidaceae based on functional analysis of gene expression profiles in Phalaenopsis aphrodite (a moth orchid) that revealed novel role...

Habitat-driven variation in mycorrhizal communities in the terrestrial orchid genus Dactylorhiza

Orchid species are critically dependent on mycorrhizal fungi for completion of their life cycle, particularly during the early stages of their development when nutritional resources are scarce. As such, orchid mycorrhizal fungi play an important role in the population dynamics, abundance, and spatial distribution of orchid species. However, less is known about the ecology and distribution of or...
