DNA barcoding involves sequencing a standard region of as tool for species identification. However, there has been no agreement on which region(s) should be used land plants. To provide community recommendation plant barcode, we have compared the performance 7 leading candidate plastid regions (atpF-atpH spacer, matK gene, rbcL rpoB rpoC1 psbK-psbI and trnH-psbA spacer). Based assessments recoverability, sequence quality, levels discrimination, recommend 2-locus combination rbcL+matK...
Ranging from huge cacti and broadleaf trees to tiny arctic flowers, flowering plants are the most vital component of global biodiversity. They provide crops that feed us, medicines, oils, fibres, herbs, spices, dyes, beverages, timber habitats for countless animals. This updated revised successor a classic book, Flowering Plants World is an authoritative, fascinating introduction Earth's colourful flora comprising comprehensive accounts more than 500 plant families. Each entry describes...
Abstract We propose in this paper to use three regions of plastid DNA as a standard protocol for barcoding all land plants. review the other markers that have been proposed and discuss their advantages disadvantages. The low levels variation make necessary; there are no regions, coding or non‐coding, evolve rapidly mitochondrial generally does animals. outline two, three‐region options, (1) rpoC1, rpoB 1matK (2) matK psbA‐trnH viable plant barcoding.
A phylogenetic analysis of the monocots was conducted on basis nucleotide sequence variation in two genes (atpA, encoded mitochondrial genome, and rbcL, plastid genome). The taxon sample 218 angiosperm terminals included 177 41 dicots. Among major results are resolution a clade comprising four magnoliid lineages (Canellales, Piperales, Magnoliales, Laurales) as sister monocots, with deepest branch within between consisting Araceae, Tofieldiaceae, Acorus, Alismatales, that includes all other...
Dried plant herbarium specimens are potentially a valuable source of DNA. Efforts to obtain genetic information from this often hindered by an inability amplifiable DNA as is typically highly degraded. post-mortem damage may not only reduce the number template molecules, but also lead generation erroneous sequence information. A qualitative and quantitative assessment essential determine accuracy molecular data specimens. In study we present miscoding lesions in using 454-sequencing...
DNA barcoding promises to revolutionize the way taxonomists work, facilitating species identification by using small, standardized portions of genome as substitutes for morphology. The concept has gained considerable momentum in many animal groups, but higher plant world been largely recalcitrant effort. In plants, efforts are concentrated on various regions plastid genome, no agreement exists what kinds ideal, though most researchers agree that more than one region is necessary. One reason...
Abstract Parasitism is a successful survival strategy across all kingdoms and has evolved repeatedly in angiosperms. Parasitic plants obtain nutrients from other some are agricultural pests. Obligate parasites, which cannot complete their lifecycle without host, may lack functional photosystems (holoparasites), or have retained photosynthesis (hemiparasites). Plastid genomes often reduced but mitochondrial not been sequenced respiratory capacities largely unknown. The hemiparasitic European...
Abstract Past phylogenetic studies of the monocot order Alismatales left several higher‐order relationships unresolved. We addressed these uncertainties using a nearly complete genus‐level sampling whole plastid genomes (gene sets representing 83 protein‐coding and ribosomal genes) from members core alismatid families, Tofieldiaceae additional taxa (Araceae other angiosperms). Parsimony likelihood analyses inferred generally highly congruent within order, alternative partitioning schemes had...
Open access to sequence data is a cornerstone of biology and biodiversity research, but has created tension under the United Nations Convention on Biological Diversity (CBD). Policy decisions could compromise research development, unless practical multilateral solution implemented. Ensuring international benefit-sharing from without jeopardising open sharing major obstacle for other UN negotiations. Here, authors propose address concerns both developing countries life scientists.
• Premise of the study: The Asparagales, with ca. 40% all monocotyledons, include a host commercially important ornamentals in families such as Orchidaceae, Alliaceae, and Iridaceae, several crop species genera Allium , Aloe Asparagus Crocus Vanilla . Though order is well defined, number recognized families, their circumscription, relationships are somewhat controversial. Methods: Phylogenetic analyses Asparagales were based on parsimony maximum likelihood using nucleotide sequence variation...
The Global Genome Biodiversity Network (GGBN) was formed in 2011 with the principal aim of making high-quality well-documented and vouchered collections that store DNA or tissue samples biodiversity, discoverable for research through a networked community biodiversity repositories. This is achieved GGBN Data Portal (http://data.ggbn.org), which links globally distributed databases bridges gap between repositories, sequence results. Advances extraction techniques combined next-generation...
Genomic samples of non-model organisms are becoming increasingly important in a broad range studies from developmental biology, biodiversity analyses, to conservation. sample definition, description, quality, voucher information and metadata all need be digitized disseminated across scientific communities. This needs concise consistent today's ever-increasing bioinformatic era, for complementary data aggregators easily map databases one another. In order facilitate exchange on genomic their...
Santalales is an order of plants consisting almost entirely parasites. Some, such as Osyris, are facultative root parasites whereas others, Viscum, obligate stem parasitic mistletoes. Here, we report the complete plastome sequences one species Osyris and three investigate evolutionary aspects structural changes in gene content relation to parasitism. Compared with typical angiosperms plastomes, four plastomes all reduced size (10-22% compared Vitis), they have experienced rearrangements,...
Parasitic plants rely on their host to cover nutritional requirements either for entire life or a smaller part of it. Depending the level parasitism, proportional reduction plastid genome has been found. However, knowledge gene loss and evolution mitogenome parasitic is only available four hemiparasitic Viscum species (Viscaceae), which lack many mitochondrial genes, while remaining genes exhibit very fast molecular rates. In this study, we include another genus, Phoradendron, from...
Asparagales are a diverse monophyletic order that has numerous species (ca. 50% of monocots) including important crop plants such as Allium, Asparagus, and Vanilla, host ornamentals irises, hyacinths, orchids. Historically, have been interest partly because their fascinating chromosomal evolution. We examine the evolutionary dynamics genomes in an updated phylogenetic framework combines analyses seven gene regions (atp1, atpB, matK, ndhF, rbcL, trnL intron, trnL-F intergenic spacer) for 79...
Abstract All diploid species of Hordeum have been included in phylogenetic analyses four molecular data sets supposedly from three different linkage groups. Two stem the nuclear genome: partial DMC1 (disrupted meiotic cDNA1) sequences (chromosome 3 H. vulgare) and EF-G (elongation factor G) 2 vulgare). The other two are RFLP sequence data, rbcL (ribulose-1,5-bisphosphate carboxylase/oxygenase), plastid genome. Incongruence length difference tests show that sets, respectively, congruent,...
The order Alismatales is a hotspot for evolution of plant mitochondrial genomes characterized by remarkable differences in genome size, substitution rates, RNA editing, retrotranscription, gene loss and intron loss. Here we have sequenced the complete mitogenomes Zostera marina Stratiotes aloides, which together with previously from Butomus Spirodela, provide new evolutionary evidence size reduction, transfer to nucleus. mitogenome includes large portion DNA transferred plastome, yet it...
