| breed | 1. A race or variety of men or other animals (or of plants), perpetuating its special or distinctive characteristics by inheritance. "Twice fifteen thousand hearts of England's breed." (Shak) "Greyhounds of the best breed." (Carpenter) 2. Class; sort; kind; of men, things, or qualities. "Are these the breed of wits so wondered at?" (Shak) "This courtesy is not of the right breed." (Shak) 3. A number produced at once; a brood. Breed is usually applied to domestic animals; species or variety to wild animals and to plants; and race to men. 1. To produce as offspring; to bring forth; to bear; to procreate; to generate; to beget; to hatch. "Yet every mother breeds not sons alike." (Shak) "If the sun breed maggots in a dead dog." (Shak) 2. To take care of in infancy, and through the age of youth; to bring up; to nurse and foster. "To bring thee forth with pain, with care to breed." (Dryden) "Born and bred on the verge of the wilderness." (Everett) 3. To educate; to instruct; to form by education; to train; sometimes followed by up. "But no care was taken to breed him a Protestant." (Bp. Burnet) "His farm may not remove his children too far from him, or the trade he breeds them up in." (Locke) 4. To engender; to cause; to occasion; to originate; to produce; as, to breed a storm; to breed disease. "Lest the place And my quaint habits breed astonishment." (Milton) 5. To give birth to; to be the native place of; as, a pond breeds fish; a northern country breeds stout men. 6. To raise, as any kind of stock. 7. To produce or obtain by any natural process. "Children would breed their teeth with less danger." (Locke) Synonym: To engender, generate, beget, produce, hatch, originate, bring up, nourish, train, instruct. Origin: OE. Breden, AS. Bredan to nourish, cherish, keep warm, from brod brood; akin to D. Broeden to brood, OHG. Bruoten, G. Bruten. See Brood. Source: Websters Dictionary (01 Mar 1998) |

| half-breed | A person who is blooded; the offspring of parents of different races, especially of the American Indian and the white race. See: Half-blooded. Source: Websters Dictionary (01 Mar 1998) |
| gene products, rev | Trans-acting nuclear proteins whose functional expression are required for HIV viral replication. Specifically, the rev gene products are required for processing and translation of the HIV gag and env mRNAs, and thus rev regulates the expression of the viral structural proteins. Rev can also regulate viral regulatory proteins. A cis-acting antirepression sequence (car) in env, also known as the rev-responsive element (rre), is responsive to the rev gene product. Rev is short for regulator of virion. (12 Dec 1998) |
| genes, rev | DNA sequences that form the coding region for a protein that regulates the expression of the viral structural and regulatory proteins in human immunodeficiency virus (HIV). Rev is short for regulator of virion. (12 Dec 1998) |
| rev | <molecular biology> A regulatory protein produced by HIV within infected cells. Rev helps transport HIV RNA sequences (messenger RNA) out from the nucleus into the cells cytoplasm, where it directs construction of proteins for new virus particles. (11 Jan 1998) |
| air plant | <botany> A plant deriving its sustenance from the air alone; an aerophyte. The "Florida moss" (Tillandsia), many tropical orchids, and most mosses and lichens are air plants. Those which are lodged upon trees, but not parasitic on them, are epiphytes. Source: Websters Dictionary (01 Mar 1998) |
| aquatic plant | <botany> Plants that must grow in water whether rooted in the mud or floating without anchorage, plants that must complete part or all of their life cycle in or near the water. (09 Oct 1997) |
| C3 plant | <plant biology> Plants that fix carbon dioxide in photosynthesis by the Calvin Benson cycle. The enzyme responsible for carbon dioxide fixation is RuDP carboxylase, whose products are compounds containing three carbon atoms. C3 plants are typical of temperate climates. Photorespiration in these plants is high. (07 Nov 1997) |
| C4 plant | <plant biology> Plants found principally in hot climates whose initial fixation of carbon dioxide in photosynthesis is by the HSK pathway. The enzyme responsible is PEP carboxylase, whose products contain four carbon atoms. Subsequently the carbon dioxide is released and re fixed by the Calvin Benson cycle. The presence of the HSK pathway permits efficient photosynthesis at high light intensities and low carbon dioxide concentrations. most species of this type have little or no photorespiration.

| vascular plant | A plant which possesses a well-developed system of conducting tissue to transport water, mineral salts and sugars. (09 Oct 1997) |
| gene expression regulation, plant | Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in plants. (12 Dec 1998) |
| genes, plant | The hereditary material of plants. (12 Dec 1998) |
| genes, structural, plant | DNA sequences that code for RNA and for the proteins required for the enzymatic and structural function of plant cells. (12 Dec 1998) |
| genome, plant | The complete gene complement contained in a set of chromosomes in a plant. (12 Dec 1998) |
| RNA, plant | Ribonucleic acid in plants having regulatory and catalytic roles as well as involvement in protein synthesis. (12 Dec 1998) |
