Knowra Nicotiana Nicotiana Nicotiana is a genus of flowering plants in the nightshade family, native chiefly to the Americas. It includes tobacco species cultivated for their leaves and ornamental species grown for their flowers.
Solanaceae : Solanaceae is a family of flowering plants that includes tomatoes, potatoes, peppers, and tobacco. Nicotiana belongs to this family, whose shared traits frame its botanical relationships.
Nicotine : Nicotine is a naturally occurring alkaloid that acts on nicotinic acetylcholine receptors in animals. Several Nicotiana species produce this potent defense chemical in their tissues.
Tobacco : Tobacco is the dried leaf of certain Nicotiana species, prepared for smoking, chewing, or other uses. The crop and its products are the genus’s most widespread human association.
Domestication of tobacco : The domestication of tobacco is the selection and cultivation of tobacco plants by human societies over generations. Human selection transformed wild Nicotiana into crops with useful leaf traits.
Tobacco industry : The tobacco industry comprises businesses involved in growing, processing, marketing, and selling tobacco products. Commercial demand for Nicotiana leaves built a powerful global industry.
Nicotiana tabacum : Nicotiana tabacum is a cultivated tobacco species whose leaves are used to make most commercial tobacco products. This domesticated species is the genus’s most economically prominent member.
Plant alkaloid : Plant alkaloids are nitrogen-containing natural compounds that often affect animals and other organisms. Nicotine belongs to this broad class of defensive chemicals produced by Nicotiana.
Tobacco cultivation : Tobacco cultivation is the agricultural production of Nicotiana plants for their harvested leaves. Growing practices have shaped the spread and domestication of tobacco species.
Indigenous peoples of the Americas : Indigenous peoples of the Americas are the diverse societies native to the continents before and after European colonization. Many American societies cultivated and used Nicotiana long before its global commercial expansion.
Atlantic slave trade : The Atlantic slave trade was the forced transportation of millions of Africans to the Americas from the sixteenth to nineteenth centuries. Enslaved labor was used on tobacco plantations in colonial America.
