Genlisea Tuberosa
''Genlisea tuberosa'' is a carnivorous species in the genus '' Genlisea'' (family Lentibulariaceae) that is endemic to Brazil and found only in ''campos rupestres'' vegetation. Lacking any roots, it has unpigmented bundles of "rootlike" subterranean organs, technically leaves, which attract, trap, and digest protozoans. This species is unique in the genus in its formation of tubers. As of 2014, ''Genlisea tuberosa'' has the smallest known genome of any flowering plant, at 61 Mbp, or 61,000,000 base pairs. Distribution and habitat ''Genlisea tuberosa'' is endemic to Brazil where it is found only in the ''campos rupestres'' vegetation in the Brazilian states of Bahia, Goiás, Distrito Federal, and Minas Gerais. It grows in fast-draining sandy soils in seasonally wet areas from altitude. It can be found growing in the presence of other species of ''Genlisea'', including '' G. aurea'', '' G. filiformis'', and '' G. violacea'', and among '' Utricularia'', '' Drosera'', ...

Federal District (Brazil)
The Federal District ( pt, Distrito Federal ) is one of 27 federative units of Brazil. Located in the Center-West Region, it is the smallest Brazilian federal unit and the only one that has no municipalities, being divided into 31 administrative regions. The federal capital of Brazil, Brasília, which is also the seat of government of the Federal District, is located in its territory. History From the first republican constitution there was already a device that foresaw the move of the federal capital from Rio de Janeiro, at that time in the former Federal District (1889-1960), to the interior of the country. In 1891 the Exploration Commission of the Central Highlands of Brazil was appointed, led by astronomer Luiz Cruls and composed of doctors, geologists and botanists, who made a study on topography, climate, geology, flora, fauna and other material resources of the region of the Central Highlands The area was known as Quadrilateral Cruls and was presented in 1894 to t ...

Genome Size
Genome size is the total amount of DNA contained within one copy of a single complete genome. It is typically measured in terms of mass in picograms (trillionths (10−12) of a gram, abbreviated pg) or less frequently in daltons, or as the total number of nucleotide base pairs, usually in megabases (millions of base pairs, abbreviated Mb or Mbp). One picogram is equal to 978 megabases. In diploid organisms, genome size is often used interchangeably with the term C-value. An organism's complexity is not directly proportional to its genome size; total DNA content is widely variable between biological taxa. Some single-celled organisms have much more DNA than humans, for reasons that remain unclear (see non-coding DNA and C-value enigma). Origin of the term The term "genome size" is often erroneously attributed to a 1976 paper by Ralph Hinegardner, even in discussions dealing specifically with terminology in this area of research (e.g., Greilhuber 2005). Notably, Hinegar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genlisea Margaretae
''Genlisea margaretae'' is a carnivorous species in the genus '' Genlisea'' (family Lentibulariaceae) native to areas of Madagascar, Tanzania, and Zambia. It has pale bundles of root-like organs up to about 20 cm long under ground that attract, trap, and digest protozoans. These organs are subterranean leaves, which lack chlorophyll. It had been known to possess the smallest known genome of any flowering plant as of 2006, but was later surpassed by the related species '' Genlisea tuberosa''. Characteristics ''Genlisea margaretae'' is a perennial herb that forms small, compact rosettes composed of nearly linear leaves about 2 mm wide. Leaves are typically 5–50 mm in length, but most of that length, including the petiole, is hidden beneath the soil. It has no true roots and instead has highly modified subterranean leaves that act as the carnivorous trapping mechanism.Taylor, Peter. (1991). ''Carnivorous Plant Newsletter'', 20(1): 20-26.

Base Pair
A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA. Dictated by specific hydrogen bonding patterns, "Watson–Crick" (or "Watson–Crick–Franklin") base pairs ( guanine– cytosine and adenine– thymine) allow the DNA helix to maintain a regular helical structure that is subtly dependent on its nucleotide sequence. The complementary nature of this based-paired structure provides a redundant copy of the genetic information encoded within each strand of DNA. The regular structure and data redundancy provided by the DNA double helix make DNA well suited to the storage of genetic information, while base-pairing between DNA and incoming nucleotides provides the mechanism through which DNA polymerase replicates DNA and RNA polymerase transcribes DNA into RNA. Many DNA-binding p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabidopsis Thaliana
''Arabidopsis thaliana'', the thale cress, mouse-ear cress or arabidopsis, is a small flowering plant native to Eurasia and Africa. ''A. thaliana'' is considered a weed; it is found along the shoulders of roads and in disturbed land. A winter annual with a relatively short lifecycle, ''A. thaliana'' is a popular model organism in plant biology and genetics. For a complex multicellular eukaryote, ''A. thaliana'' has a relatively small genome around 135 megabase pairs. It was the first plant to have its genome sequenced, and is a popular tool for understanding the molecular biology of many plant traits, including flower development and light sensing. Description ''Arabidopsis thaliana'' is an annual (rarely biennial) plant, usually growing to 20–25 cm tall. The leaves form a rosette at the base of the plant, with a few leaves also on the flowering stem. The basal leaves are green to slightly purplish in color, 1.5–5 cm long, and 2–10 mm broad, wit ...

Angiosperm
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ancestor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drosera
''Drosera'', which is commonly known as the sundews, is one of the largest genera of carnivorous plants, with at least 194 species. 2 volumes. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow. Various species, which vary greatly in size and form, are native to every continent except Antarctica.McPherson, S.R. 2008. ''Glistening Carnivores''. Redfern NaturalHistory Productions Ltd., Poole. Charles Darwin performed much of the early research into ''Drosera'', engaging in a long series of experiments with Drosera rotundifolia which were the first to confirm carnivory in plants. In an 1860 letter, Darwin wrote, “…at the present moment, I care more about ''Drosera'' than the origin of all the species in the world.” Both the botanical name (from the Greek δρόσος: ''drosos'' = "dew, d ...

Utricularia
''Utricularia'', commonly and collectively called the bladderworts, is a genus of carnivorous plants consisting of approximately 233 species (precise counts differ based on classification opinions; a 2001 publication lists 215 species).Salmon, Bruce (2001). ''Carnivorous Plants of New Zealand''. Ecosphere Publications. They occur in fresh water and wet soil as terrestrial or aquatic species across every continent except Antarctica. ''Utricularia'' are cultivated for their flowers, which are often compared with those of snapdragons and orchids, especially amongst carnivorous plant enthusiasts. All ''Utricularia'' are carnivorous and capture small organisms by means of bladder-like traps. Terrestrial species tend to have tiny traps that feed on minute prey such as protozoa and rotifers swimming in water-saturated soil. The traps can range in size from .Taylor, Peter. (1989).
