Genlisea
''Genlisea'' ( ) is a genus of carnivorous plants also known as corkscrew plants. The 30 or so species grow in wet terrestrial to semi-aquatic environments distributed throughout Africa and Central and South America. The plants use highly modified underground leaves to attract, trap and digest minute microfauna, particularly protozoans. Although suggested a century earlier by Charles Darwin, carnivory in the genus was not proven until 1998. The generic name ''Genlisea'' honors the French writer and educator Stéphanie Félicité Ducrest de St-Albin, comtesse de Genlis. Several species in the genus, including '' G. margaretae'', '' G. aurea'', and '' G. tuberosa'', possess the smallest known genomes of all flowering plants. As stated, ''Genlisea'' has a wide range of genetic diversity which can be shown in various phenotypic traits. For example, ''G. tuberosa'' develops tubers, 1-3 occurring per plant. This allows for carbohydrate and water storage as it is found in areas prone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genlisea Aurea
''Genlisea aurea'' is one of the largest carnivorous species in the genus ''Genlisea'' (family Lentibulariaceae). It has pale bundles of root-like organs up to about 15 cm long under ground that attract, trap, and digest protozoans. These organs are subterranean leaves, which lack chlorophyll. ''G. aurea'' is endemic to Brazil, where it grows with several other species of ''Genlisea''. It possesses an exceptionally small genome for a flowering plant. Characteristics ''Genlisea aurea'' 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. The rosettes can grow to be as big as 5 cm wide. It has no true roots and instead has highly modified subterranean leaves that act as the carnivorous trapping mechanism. The up to 40 cm tall inflorescence produces one to three flowers at its apex ... [...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''.

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'', and some g ...

Carnivorous Plant
Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans Protozoa (singular: protozoan or protozoon; alternative plural: protozoans) are a group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic tissues and debris. Histo ..., typically insects and other arthropods. Carnivorous plants still generate some of their energy from photosynthesis. Carnivorous plants have adapted to grow in places where the soil is thin or poor in soil nutrient, nutrients, especially nitrogen, such as acidic bogs. They can be found on all continents except Antarctica, as well as many Pacific islands. In 1875 Charles Darwin published ''Insectivorous Plants (book), Insectivorous Plants'', the first treatise to recognize the significance of carnivory in plants, describing years of painstaking research. True carnivory is believed to have convergent evoluti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lentibulariaceae
Lentibulariaceae is a family of carnivorous plants containing three genera: ''Genlisea'', the corkscrew plants; ''Pinguicula'', the butterworts; and ''Utricularia'', the bladderworts. The genera ''Polypompholyx'' (two species of pink petticoats or fairy aprons) and ''Biovularia'' used to be regarded as fourth and fifth members of this family. ''Biovularia'' has been subsumed into ''Utricularia'', and ''Polypompholyx'' has been relegated to a subgenus of ''Utricularia''. Placement of the family used to be in the Scrophulariales, which has been merged with Lamiales in the Angiosperm Phylogeny Group system. Evolution Carnivory in plants appears to have evolved independently in four major angiosperm lineages and five orders: Poales, Caryophyllales, Oxalidales, Ericales, and Lamiales. One common trait found in several Lamiales families that may have led to carnivory is the secretion of proteinase mucilage through leaf surfaces. This mucilage is generally used to prevent insect pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Barthlott
Wilhelm Barthlott (born 1946 in Forst, Germany) is a German botanist and biomimetic materials scientist. His official botanical author citation is Barthlott. Barthlott's areas of specialization are biodiversity (Global distribution, assessment, and change in biodiversity) and Bionics/Biomimetics (in particular, superhydrophobic biological surfaces and their technical applications). He is one of the pioneers in the field of biological and technical interfaces. Based on his systematic research on plant surfaces, he developed self-cleaning (lotus effect) technical surfaces and technical surfaces, which permanently retain air under water (Salvinia effect). This led to a paradigm shift in particular areas of material science and facilitated the development of superhydrophobic biomimetic surfaces. His map of the global biodiversity distribution is the foundation for numerous research topics. Barthlott has been honored with many awards (e. g. the German Environment Award) and membership ...

Genome
In the fields of molecular biology and genetics, a genome is all the genetic information of an organism. It consists of nucleotide sequences of DNA (or RNA in RNA viruses). The nuclear genome includes protein-coding genes and non-coding genes, other functional regions of the genome such as regulatory sequences (see non-coding DNA), and often a substantial fraction of 'junk' DNA with no evident function. Almost all eukaryotes have mitochondria and a small mitochondrial genome. Algae and plants also contain chloroplasts with a chloroplast genome. The study of the genome is called genomics. The genomes of many organisms have been sequenced and various regions have been annotated. The International Human Genome Project reported the sequence of the genome for ''Homo sapiens'' in 200The Human Genome Project although the initial "finished" sequence was missing 8% of the genome consisting mostly of repetitive sequences. With advancements in technology that could handle sequenci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnivorous Plant Newsletter
The ''Carnivorous Plant Newsletter'' is the official publication of the International Carnivorous Plant Society (ICPS), the largest such organization in the world. It is headquartered in Walnut Creek, California. History and editorship The newsletter has been published every year since its inception in 1972. It was first published as a stenciled product, with annual subscription priced at $1 for those in the contiguous United States, Mexico and Canada, and $2 for those living elsewhere. The first issue, from April 1972, opened with the following paragraph: In 1972 the newsletter had around 25 subscribers; this number quickly grew to more than 100 by June 29 of that year and reached 600 in July 1976. In 2018, the quarterly print run is 1400 copies. In volume 7 (1978), the newsletter started printing in a 6 by 9 inch format with colour covers, and limited colour reproduction in some articles. The publication was founded by Don Schnell and Joe Mazrimas. Additional early edit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Root
In vascular plants, the roots are the organs of a plant that are modified to provide anchorage for the plant and take in water and nutrients into the plant body, which allows plants to grow taller and faster. They are most often below the surface of the soil, but roots can also be aerial or aerating, that is, growing up above the ground or especially above water. Function The major functions of roots are absorption of water, plant nutrition and anchoring of the plant body to the ground. Anatomy Root morphology is divided into four zones: the root cap, the apical meristem, the elongation zone, and the hair. The root cap of new roots helps the root penetrate the soil. These root caps are sloughed off as the root goes deeper creating a slimy surface that provides lubrication. The apical meristem behind the root cap produces new root cells that elongate. Then, root hairs form that absorb water and mineral nutrients from the soil. The first root in seed producing plants is the r ...
