Artichoke economically important genes from related species. Rezazadeh, A., Ghasemnezhad, A., Barani, M., & Telmadarrehei, T. (2012). Effect of Salinity on Phenolic Composition and Antioxidant Activity of Artichoke (Cynara scolymus L.) Leaves. Research Journal of Medicinal Plant, 6(3). Artichoke The globe artichoke ("Cynara cardunculus" var. "scolymus") is a variety of a species of thistle cultivated as a food. The edible portion of the plant consists of the flower buds before the flowers come into bloom. The budding artichoke flower-head is a cluster of many budding small flowers (an inflorescence), together with many bracts, on an edible base. Once the buds bloom,
Algebraic variety was not complete (the analog of compactness), but soon afterwards he found an algebraic surface that was complete and non-projective. Since then other examples have been found. A subvariety is a subset of a variety that is itself a variety (with respect to the structure induced from the ambient variety). For example, every open subset of a variety is a variety. See also closed immersion. Hilbert's Nullstellensatz says that closed subvarieties of an affine or projective variety are in one-to-one correspondence with the prime ideals or homogeneous prime ideals of the coordinate ring of the variety.
