Watermelon is a different genus, CITRULLUS. Bitter melon may refer to MOMORDICA or this genus.Cucumis sativus: A creeping annual plant species of the CUCURBITACEAE family. It has a rough succulent, trailing stem and hairy leaves with three to five pointed lobes.Cucurbitaceae: The gourd plant family of the order Violales, subclass Dilleniidae, class Magnoliopsida. It is sometimes placed in its own order, Cucurbitales. 'Melon' generally refers to CUCUMIS; CITRULLUS; or MOMORDICA.Books, Illustrated: Books containing photographs, prints, drawings, portraits, plates, diagrams, facsimiles, maps, tables, or other representations or systematic arrangement of data designed to elucidate or decorate its contents. (From The ALA Glossary of Library and Information Science, 1983, p114)Citrullus: A plant genus of the family CUCURBITACEAE known for the edible fruit.Cucurbita: A plant genus of the family CUCURBITACEAE, order Violales, subclass Dilleniidae, which includes pumpkin, gourd and squash.Peronospora: A genus of OOMYCETES in the family Peronosporaceae. Most species are obligatory parasites and many are plant pathogens.Coriandrum: A plant genus of the family APIACEAE. The leaves are the source of cilantro and the seeds are the source of coriander, both of which are used in SPICES.History, 15th Century: Time period from 1401 through 1500 of the common era.Lawsonia Plant: A plant genus of the family LYTHRACEAE that is the source of henna and has cytotoxic activity.Ascorbate Oxidase: An enzyme that converts ascorbic acid to dehydroascorbic acid. EC, Medieval: The period of history from the year 500 through 1450 of the common era.Cotyledon: A part of the embryo in a seed plant. The number of cotyledons is an important feature in classifying plants. In seeds without an endosperm, they store food which is used in germination. In some plants, they emerge above the soil surface and become the first photosynthetic leaves. (From Concise Dictionary of Biology, 1990)Persia: An ancient civilization, known as early as 2000 B.C. The Persian Empire was founded by Cyrus the Great (550-529 B.C.) and for 200 years, from 550 to 331 B.C., the Persians ruled the ancient world from India to Egypt. The territory west of India was called Persis by the Greeks who later called the entire empire Persia. In 331 B.C. the Persian wars against the Greeks ended disastrously under the counterattacks by Alexander the Great. The name Persia in modern times for the modern country was changed to Iran in 1935. (From Webster's New Geographical Dictionary, 1988, p546 & Asimov, Words on the Map, 1962, p176)Protochlorophyllide: A photo-active pigment localized in prolamellar bodies occurring within the proplastids of dark-grown bean leaves. In the process of photoconversion, the highly fluorescent protochlorophyllide is converted to chlorophyll.Plant Roots: The usually underground portions of a plant that serve as support, store food, and through which water and mineral nutrients enter the plant. (From American Heritage Dictionary, 1982; Concise Dictionary of Biology, 1990)Toxicodendron: A genus (formerly part of Rhus genus) of shrubs, vines, or trees that yields a highly allergenic oleoresin which causes a severe contact dermatitis (DERMATITIS, TOXICODENDRON). The most toxic species are Toxicodendron vernix (poison sumac), T. diversilobum (poison oak), and T. radicans (poison ivy). T. vernicifera yields a useful varnish from which certain enzymes (laccases) are obtained.Glutamate Synthase (NADH): A FLAVOPROTEIN enzyme for AMMONIA assimilation in BACTERIA, microorganisms and PLANTS. It catalyzes the oxidation of 2 molecules of L-GLUTAMATE to generate L-GLUTAMINE and 2-oxoglutarate in the presence of NAD+.Fruit: The fleshy or dry ripened ovary of a plant, enclosing the seed or seeds.Plant Proteins: Proteins found in plants (flowers, herbs, shrubs, trees, etc.). The concept does not include proteins found in vegetables for which VEGETABLE PROTEINS is available.Chromosomes, Plant: Complex nucleoprotein structures which contain the genomic DNA and are part of the CELL NUCLEUS of PLANTS.Genome, Plant: The genetic complement of a plant (PLANTS) as represented in its DNA.Crops, Agricultural: Cultivated plants or agricultural produce such as grain, vegetables, or fruit. (From American Heritage Dictionary, 1982)Gene Expression Regulation, Plant: Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in plants.Disease Resistance: The capacity of an organism to defend itself against pathological processes or the agents of those processes. This most often involves innate immunity whereby the organism responds to pathogens in a generic way. The term disease resistance is used most frequently when referring to plants.Ethylenes: Derivatives of ethylene, a simple organic gas of biological origin with many industrial and biological use.Plant Leaves: Expanded structures, usually green, of vascular plants, characteristically consisting of a bladelike expansion attached to a stem, and functioning as the principal organ of photosynthesis and transpiration. (American Heritage Dictionary, 2d ed)DNA, Plant: Deoxyribonucleic acid that makes up the genetic material of plants.Plant Diseases: Diseases of plants.Genes, Plant: The functional hereditary units of PLANTS.Pollination: The transfer of POLLEN grains (male gametes) to the plant ovule (female gamete).DNA, Chloroplast: Deoxyribonucleic acid that makes up the genetic material of CHLOROPLASTS.Plants: Multicellular, eukaryotic life forms of kingdom Plantae (sensu lato), comprising the VIRIDIPLANTAE; RHODOPHYTA; and GLAUCOPHYTA; all of which acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations.Plant Growth Regulators: Any of the hormones produced naturally in plants and active in controlling growth and other functions. There are three primary classes: auxins, cytokinins, and gibberellins.Phylogeny: The relationships of groups of organisms as reflected by their genetic makeup.Seedling: Very young plant after GERMINATION of SEEDS.
