Tobacco is the common name of several plants in the genus Nicotiana of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. More than 70 species of tobacco are known, but the chief commercial crop is N. tabacum. The more potent variant N. rustica is also used in some countries.
Nicotiana is a genus of herbaceous plants and shrubs in the family Solanaceae, that is indigenous to the Americas, Australia, Southwestern Africa and the South Pacific. Various Nicotiana species, commonly referred to as tobacco plants, are cultivated as ornamental garden plants. N. tabacum is grown worldwide for the cultivation of tobacco leaves used for manufacturing and producing tobacco products, including cigars, cigarillos, cigarettes, chewing tobacco, dipping tobacco, snuff, and snus.
Nicotiana glauca is a species of flowering plant in the tobacco genus Nicotiana of the nightshade family Solanaceae. It is known by the common name tree tobacco. Its leaves are attached to the stalk by petioles, and its leaves and stems are neither pubescent nor sticky like Nicotiana tabacum. It resembles Cestrum parqui but differs in the form of leaves and fusion of the outer floral parts. It grows to heights of more than two meters.
Nicotiana rustica, commonly known as Aztec tobacco or strong tobacco, is a rainforest plant in the family Solanaceae. It is a very potent variety of tobacco, containing up to nine times more nicotine than common species of Nicotiana such as Nicotiana tabacum. More specifically, N. rustica leaves have a nicotine content as high as 9%, whereas N. tabacum leaves contain about 1 to 3%. The high concentration of nicotine in its leaves makes it useful for producing pesticides, and it has a wide variety of uses specific to cultures around the world. However, N. rustica is no longer cultivated in its native North America, as N. tabacum has replaced it.
Nicotiana benthamiana, colloquially known as benth or benthi, is a species of Nicotiana indigenous to Australia. It is a close relative of tobacco.
Nicotiana tabacum, or cultivated tobacco, is an annually grown herbaceous plant of the genus Nicotiana. N. tabacum is the most commonly grown species in the genus Nicotiana, as the plant's leaves are commercially harvested to be processed into tobacco for human use. The plant is tropical in origin, is commonly grown throughout the world, and is often found in cultivation. It grows to heights between 1 and 2 meters. Research is ongoing into its ancestry among wild Nicotiana species, but it is believed to be a hybrid of Nicotiana sylvestris, N. tomentosiformis, and possibly N. otophora.
Anabasine is a pyridine and piperidine alkaloid found in the Tree Tobacco plant, as well as in the close relative of the common tobacco plant. It is a structural isomer of, and chemically similar to, nicotine. Its principal (historical) industrial use is as an insecticide.
Latakia tobacco is a sun-dried and smoke-cured tobacco product. It originated in Syria and is named after its major port city of Latakia, though large production has permanently moved to Cyprus due to varying and compounding sociopolitical issues within Syrian borders. It is in the family of fire-cured tobaccos in which the leaves are dried(cured) over burning hard wood. what sets Latakia apart from other fire-cured tobaccos is the use of heavy volumes of smoke from both dried and live material from aromatic woods.
Pituri, also known as mingkulpa, is a mixture of leaves and wood ash traditionally chewed as a stimulant by Aboriginal Australians widely across the continent. Leaves are gathered from any of several species of native tobacco (Nicotiana) or from at least one distinct population of the species Duboisia hopwoodii. Various species of Acacia, Grevillea and Eucalyptus are burned to produce the ash. The term "pituri" may also refer to the plants from which the leaves are gathered or from which the ash is made. Some authors use the term to refer only to the plant Duboisia hopwoodii and its leaves and any chewing mixture containing its leaves.
The bearded mountaineer or eastern mountaineer is a species of hummingbird in the "coquettes", tribe Lesbiini of subfamily Lesbiinae. It is endemic to Peru.
Mark Wayne Chase is a US-born British botanist. He is noted for work in plant classification and evolution, and one of the instigators of the Angiosperm Phylogeny Group-classification for flowering plants which is partly based on DNA studies. In particular he has researched orchids, and currently investigates ploidy and hybridization in Nicotiana.
Scrobipalpa aptatella is a moth of the family Gelechiidae. It is found in China (Xinjiang), Australia, New Zealand, Samoa, India, Indonesia (Sumatra), Malaysia, Myanmar, Sri Lanka, Palestine and in Africa, where it has been recorded from the Democratic Republic of Congo, Kenya, Malawi, Namibia, South Africa, Tanzania and Zimbabwe.
Nicotiana quadrivalvis is a species of wild tobacco known as Indian tobacco. The variety N. quadrivalvis var. multivalvis is known by the common name Columbian tobacco. It is endemic to the western United States, where it grows in many types of habitat. It is a bushy, sprawling annual herb growing up to two meters in maximum height. The lower leaf blades are up to 15 centimetres (6 in) long and are borne on short petioles, the upper smaller and sessile on the stem. The inflorescence is an array of several white, greenish, or purple-tinged flowers with tubular throats up to 5 centimeters long. The base of each is enclosed in a ridged calyx of sepals. The flower face may be 5 centimetres (2 in) wide. The fruit is a capsule up to 2 centimetres in length.
Nicotiana attenuata is a species of wild tobacco known by the common name coyote tobacco. It is native to western North America from British Columbia to Texas and northern Mexico, where it grows in many types of habitat. It is a glandular and sparsely hairy annual herb exceeding a meter in maximum height. The leaf blades may be 10 centimetres (4 in) long, the lower ones oval and the upper narrower in shape, and are borne on petioles. The inflorescence bears several flowers with pinkish or greenish white tubular throats 2 to 3 centimetres long, their bases enclosed in pointed sepals. The flower face has five mostly white lobes. The fruit is a capsule about 1 centimetre long.
Myosmine is an alkaloid found in tobacco and other plants. Chemically, it is closely related to nicotine. It inhibits aromatase sevenfold more potently than nicotine. It also releases dopamine in adult but not adolescent rats.
Nicotiana glutinosa is a species of tobacco plant that is economically important in tobacco hybrids. N. glutinosa is native to western South America, including Bolivia, Ecuador, and Peru. It is a model organism for the study of Tobacco mosaic virus resistance in tobacco.
The Solanaceae, or the nightshades, are a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
Bhyravabhotla Radhakrishna Murty (1928–2003) was an Indian botanist, known for his contributions the fields of Conservation genetics and Radiation genetics. He was a professor of Biochemistry Division at Indian Agricultural Research Institute, Pusa and was an elected fellow of Indian Academy of Sciences and the Indian National Science Academy. The Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology, one of the highest Indian science awards, in 1973, for his contributions to biological sciences.
Nicotiana rustica is a plant in the family Solanaceae, native to Western Australia, South Australia and the Northern Territory.
