Odontites
''Odontites'' is a genus of flowering plants in the family Orobanchaceae. Phylogeny The phylogeny of the genera of Rhinantheae has been explored using molecular characters. ''Odontites'' belongs to the core Rhinantheae. It is the sister genus to ''Bellardia'', and then to ''Tozzia'' and ''Hedbergia''. These taxa are closely related to the genus ''Euphrasia''. In turn, these five genera share phylogenetic affinities with ''Bartsia''.

Odontites Vernus
''Odontites vernus'', the red bartsia, is a wild flower from the family Orobanchaceae native to Europe and Asia and occurring as an alien in North America. The red bartsia is a common plant in low-fertility soils, where it lives partially as a parasite on the roots of grasses. The red bartsia has pinkish and red flowers from June to September. They prefer dry conditions and full sun light exposure and are pollinated by bees and wasps. Over the last 70 years, the red bartsia has disappeared from many woodland locations in the English county of Dorset. In Manitoba, Canada, the plant known as red bartsia is considered a weed. Etymology ''Odontites'' is derived from Greek and means 'tooth-related', a name which is in reference to Pliny the Elder Gaius Plinius Secundus (AD 23/2479), called Pliny the Elder (), was a Roman author, naturalist and natural philosopher, and naval and army commander of the early Roman Empire, and a friend of the emperor Vespasian. He wrote the encyclo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhinantheae
Rhinantheae is a tribe with less than 20 genera of herbaceous plants in the family Orobanchaceae. Phylogeny The phylogeny of the genera of Rhinantheae has been explored using DNA markers. Three assemblages can be distinguished in this tribe: * ''Rhinanthus'' is the sister genus to ''Lathraea'', and then to ''Rhynchocorys''. These taxa are closely related to the core Rhinanteae. * In the core Rhinantheae, ''Odontites'' sensu lato, including ''Bornmuellerantha'' and ''Bartsiella'', is the sister genus to ''Bellardia'', including ''Parentucellia'' and ''Bartsia canescens'' + ''B. mutica''. These taxa are closely related to ''Hedbergia'' (including ''Bartsia decurva'' + ''B. longiflora'') and ''Tozzia''. In turn, these genera share phylogenetic affinities with ''Euphrasia'', and then with ''Bartsia'' sensu stricto (''Bartsia alpina''). * ''Melampyrum'' occupies an isolated, deep-branching position. The median crown age of Rhinantheae was estimated to be ca. 30 Myr. Systematics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orobanchaceae
Orobanchaceae, the broomrapes, is a family of mostly parasitic plants of the order Lamiales, with about 90 genera and more than 2000 species. Many of these genera (e.g., ''Pedicularis'', ''Rhinanthus'', ''Striga'') were formerly included in the family Scrophulariaceae ''sensu lato''. With its new circumscription, Orobanchaceae forms a distinct, monophyletic family. From a phylogenetic perspective, it is defined as the largest crown clade containing '' Orobanche major'' and relatives, but neither ''Paulownia tomentosa'' nor ''Phryma leptostachya'' nor '' Mazus japonicus''. The Orobanchaceae are annual herbs or perennial herbs or shrubs, and most (all except ''Lindenbergia'', ''Rehmannia'' and ''Triaenophora'') are parasitic on the roots of other plants—either holoparasitic or hemiparasitic (fully or partly parasitic). The holoparasitic species lack chlorophyll and therefore cannot perform photosynthesis. Description Orobanchaceae is the largest of the 20–28 dicot fami ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear DNA
Nuclear DNA (nDNA), or nuclear deoxyribonucleic acid, is the DNA contained within each cell nucleus of a eukaryotic organism. It encodes for the majority of the genome in eukaryotes, with mitochondrial DNA and plastid DNA coding for the rest. It adheres to Mendelian inheritance, with information coming from two parents, one male and one female—rather than matrilineally (through the mother) as in mitochondrial DNA. Structure Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells. Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin. Each strand is a long polymer chain of repeating nucleotides. Each nucleotide is composed of a five-carbon sugar, a phosphate group, and an organic base. Nucleotides are distinguished by their bases: purines, large bases that include adenine and guanine; and pyr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chloroplast DNA
Chloroplast DNA (cpDNA) is the DNA located in chloroplasts, which are photosynthetic organelles located within the cells of some eukaryotic organisms. Chloroplasts, like other types of plastid, contain a genome separate from that in the cell nucleus. The existence of chloroplast DNA was identified biochemically in 1959, and confirmed by electron microscopy in 1962. The discoveries that the chloroplast contains ribosomes and performs protein synthesis revealed that the chloroplast is genetically semi-autonomous. The first complete chloroplast genome sequences were published in 1986, ''Nicotiana tabacum'' (tobacco) by Sugiura and colleagues and ''Marchantia polymorpha'' (liverwort) by Ozeki et al. Since then, a great number of chloroplast DNAs from various species have been sequenced. Molecular structure Chloroplast DNAs are circular, and are typically 120,000–170,000 base pairs long. They can have a contour length of around 30–60 micrometers, and have a mass of about 80â ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Transcribed Spacer
Internal transcribed spacer (ITS) is the spacer DNA situated between the small-subunit ribosomal RNA (rRNA) and large-subunit rRNA genes in the chromosome or the corresponding transcribed region in the polycistronic rRNA precursor transcript. ITS across life domains In bacteria and archaea, there is a single ITS, located between the 16S and 23S rRNA genes. Conversely, there are two ITSs in eukaryotes: ITS1 is located between 18S and 5.8S rRNA genes, while ITS2 is between 5.8S and 28S (in opisthokonts, or 25S in plants) rRNA genes. ITS1 corresponds to the ITS in bacteria and archaea, while ITS2 originated as an insertion that interrupted the ancestral 23S rRNA gene. Organization In bacteria and archaea, the ITS occurs in one to several copies, as do the flanking 16S and 23S genes. When there are multiple copies, these do not occur adjacent to one another. Rather, they occur in discrete locations in the circular chromosome. It is not uncommon in bacteria to carry tRN ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra Nevada (Spain)
Sierra Nevada (; meaning "mountain range covered in snow") is a mountain range in the Andalusian province of Granada in Spain. It contains the highest point of continental Spain:The highest peak in Spanish territory is Teide on the island of Tenerife in the Canary Islands, which is politically Spanish but geographically part of Africa. Mulhacén, at above sea level. It is a popular tourist destination, as its high peaks make skiing possible in one of Europe's most southerly ski resorts, in an area along the Mediterranean Sea predominantly known for its warm temperatures and abundant sunshine. At its foothills is found the city of Granada, and a little further south, AlmerÃa and Málaga. Parts of the range have been included in the Sierra Nevada National Park. The range has also been declared a biosphere reserve. The Sierra Nevada Observatory and the IRAM radiotelescope are located on the northern slopes at an elevation of .
