Species name: Datura metel
Datura metel is a plant possibly native to Asia. It is famous for the effects of its flower on the nervous system when ingested. All parts of Datura plants contain dangerous levels of tropane alkyloids (highly poisonous) and may be fatal if ingested by humans or other animals, including livestock and pets. In some places it is prohibited to buy, sell or cultivate Datura plants. In regulated quantities however, Datura has been traditionally used in Chinese and Indian medicines.

| Magnoliophyta | Also called Angiospermae. The ancestors of flowering plants diverged from gymnosperms around 245–202 million years ago, and the first flowering plants known to exist are from 140 million years ago. They diversified enormously during the Lower Cretaceous and became widespread around 100 million years ago, but replaced conifers as the dominant trees only around 60-100 million years ago. | These are seed plants like Gymnosperms, but can be differentiated by the presence of flowers, seeds containing endosperm and seeds that produce a fruit. Angiosperms are the most diverse and highly evolutionarily successful group of land plants. |

| Magnoliopsida | Magnoliopsida is the scientific name for dicots. This class contains about ~1,99,350 species of Angiosperms. Eudicots are a subset of Dicots. Based on chloroplast DNA sequences, the divergence date between monocots and dicots is estimated to be ~200 million years, with a 40 million years uncertainty. | Dicots are diverse in habit, with half of all the species being more or less woody-stemmed - a reflection of the usual presence of a vascular cambium in the class. Annuals, biennials, vines, epiphytes, aquatics, parasites, and saprotrophs are also well represented in dicots. Vascular bundles of the stem are usually borne in a ring that encloses the pith. Vessel elements present except in some putatively primitive woody or aquatic families. Most dicots have a primary root system derived from the radicle, although some have an adventitious root system commonly seen in the class of monocots. Cotyledons are usually 2, seldom 1, 3, or 4. Leaves are mostly net-veined. |

Pubmed Word cloud
This word cloud is obtained using the tool LigerCat by searching the Pubmed database. LigerCat builds the cloud from the most relevant Medical Subject Headings (MeSH) terms. Each term's relative size indicates how many times it appears in the PubMed search results. Click on a term to access the full LigerCat cloud, with live PubMed search capabilities. LigerCat has been developed for the Biology of Aging Project.

- If there is an error message below, it means that there is no retrievable information available on NCBI
- If the number of nucleotide sequences is less than 100, very little genomic work has been done on this species. A respectable number of nucleotide sequences is above 10000.
- Most of the nucleotide sequences may come from three sources:
- Studies on single genes, where people try to sequence genes such as some specific dehydrogenases important,say, for tannin production
- Sequences of Ribosomal Internal Transcribed Spacer, whose sequence is used for generating molecular phylogenetic trees to establish species relationships
- Expressed Sequence Tags (ESTs) which can tell about which genes are present and expressed in the species at a particular time in the given tissue
