Asterales is an order of dicotyledonous flowering plants that includes the large family Asteraceae known for composite flowers made of florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals.
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques. The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination". A wide variety of organisms have been genetically modified (GM), including animals, plants, and microorganisms.
Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms.
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance, but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are.
Horizontal gene transfer (HGT) or lateral gene transfer (LGT) is the movement of genetic material between organisms other than by the ("vertical") transmission of DNA from parent to offspring (reproduction). HGT is an important factor in the evolution of many organisms. HGT is influencing scientific understanding of higher-order evolution while more significantly shifting perspectives on bacterial evolution.
Lobelia is a genus of flowering plants in the family Campanulaceae comprising 415 species, with a subcosmopolitan distribution primarily in tropical to warm temperate regions of the world, a few species extending into cooler temperate regions. They are known generally as lobelias.
The family Campanulaceae, of the order Asterales, contains nearly 2400 species in 84 genera of herbaceous plants, shrubs, and rarely small trees, often with milky sap. Among them are several familiar garden plants belonging to the genera Campanula (bellflower), Lobelia, and Platycodon (balloonflower). Campanula rapunculus and Codonopsis lanceolata are eaten as vegetables. Lobelia inflata, L. siphilitica and L. tupa and others have been used as medicinal plants. Campanula rapunculoides may be a troublesome weed, particularly in gardens, while Legousia spp. may occur in arable fields.
Oryza sativa, having the common name Asian cultivated rice, is the much more common of the two rice species cultivated as a cereal, the other species being O. glaberrima, African rice. It was first domesticated in the Yangtze River basin in China 13,500 to 8,200 years ago.
The Hawaiian lobelioids are a group of flowering plants in the bellflower family, Campanulaceae, subfamily Lobelioideae, all of which are endemic to the Hawaiian Islands. This is the largest plant radiation in the Hawaiian Islands, and indeed the largest on any island archipelago, with over 125 species. The six genera involved can be broadly separated based on growth habit: Clermontia are typically branched shrubs or small trees, up to 7 metres (23 ft) tall, with fleshy fruits; Cyanea and Delissea are typically unbranched or branching only at the base, with a cluster of relatively broad leaves at the apex and fleshy fruits; Lobelia and Trematolobelia have long thin leaves down a single, non-woody stem and capsular fruits with wind-dispersed seeds; and the peculiar Brighamia have a short, thick stem with a dense cluster of broad leaves, elongate white flowers, and capsular fruits. The relationships among the genera and sections remains unsettled as of April 2022.
Lobelia deckenii is a species of flowering plant in the family Campanulaceae. It is a giant lobelia endemic to the mountains of Tanzania. It is listed as a threatened plant of the forests of Cherangani hills, Kenya. It grows in moist areas, such as valley bottoms and moorland, in contrast to Lobelia telekii which grows in a similar but drier habitat. These two species produce occasional hybrids. Lobelia deckenii plants usually produce multiple rosettes. Each rosette grows for several decades, produces a single large inflorescence and hundreds of thousands of seeds, then dies. Because individual plants have multiple rosettes, they survive to reproduce repeatedly, and plants with more rosettes flower more frequently. It is iteroparous.
Lobelia telekii is a species of flowering plant in the family Campanulaceae, that is found only in the alpine zones of Mount Kenya, Mount Elgon, and the Aberdare Mountains of East Africa. It occurs at higher altitudes on well-drained sloped hillsides. It is a semelparous species, putting all its reproductive effort into producing single large inflorescence up to 3 metres (10 ft) tall, and then dying. Inflorescences of L. telekii also possesses a large pith-volume for internal water storage and marcescent foliage which could provide insulation. It secretes a polysaccharide into this reservoir, which may be useful for its survival in the cold climate. The plant is named after the Austro-Hungarian explorer, Count Sámuel Teleki.
Lobelia aberdarica is a species of plant in the family Campanulaceae. It is restricted to the uplands of Kenya and Uganda (1860-3350m). It has been found in the forests of Cherangani hills, Kenya. Its natural habitats are lower and upper montane and subalpine swamps and meadows. It has been brought into cultivation.
Lobelia columnaris is a species of plant in the family Campanulaceae. It is the only giant Lobelia occurring in West Africa and is found in Cameroon and Equatorial Guinea. Its natural habitat is subtropical or tropical dry forests.
Lobelia siphilitica, the great blue lobelia, great lobelia, or blue cardinal flower, is a plant species within the family Campanulaceae. It is an herbaceous perennial dicot native to eastern and central Canada and United States. There are two recognized varieties of Lobelia siphilitica, var. siphilitica and var. ludoviciana. Blooming from August to October, it is short-lived, lasting only for a few years.
Lobelia chinensis, commonly known as Asian lobelia, Chinese lobelia, and Herba Lobellae Chinensis, is a species of flowering plant in the family Campanulaceae. It is one of the 50 fundamental herbs used in traditional Chinese medicine, where it has the name.
Dendrosenecio is a genus of flowering plants in the sunflower family. It is a segregate of Senecio, in which it formed the subgenus Dendrosenecio. Its members, the giant groundsels, are native to the higher altitude zones of ten mountain groups in equatorial East Africa, where they form a conspicuous element of the flora.
Giant lobelia is a common name for several plants in the genus Lobelia; many of these species are restricted to high altitude, alpine ecosystems. In East African highlands as many as 20 species were listed in 1934 (Bruce). A selection of species names is below.
Lobelia polyphylla, called the tabaco del Diablo, is a species of flowering plant in the family Campanulaceae, native to northern and central Chile. When smoked, it has narcotic and hallucinogenic effects.
Arsi Mountains National Park is a national park in Arsi Zone of Oromia Region in Ethiopia. It protects a portion of the Ethiopian Highlands and includes montane forests, subalpine heath, and alpine grasslands and shrublands. The park was designated in 2011 and covers an area of 10876 km2.
Lobelia giberroa is a flowering plant of the bellfower family (Campanulaceae). It is native to the Mountains of the Moon Massif in Uganda. It is the tallest of all the giant Lobelia species at up to 33 feet. Its creme de menthe flowers form a spikelike raceme.
