A plant genus of the family JUGLANDACEAE that bears edible nuts.
A plant family of the order Urticales, subclass Hamamelidae, class Magnoliopsida. Members are trees and shrubs of temperate regions that have watery sap and alternate leaves which are lopsided at the base. The flowers lack petals.
A plant genus of the family CUPRESSACEAE. Cypress ordinarily refers to this but also forms part of the name of plants in other genera.
A geographic area of east and southeast Asia encompassing CHINA; HONG KONG; JAPAN; KOREA; MACAO; MONGOLIA; and TAIWAN.
A syndrome characterized by HYPERPIGMENTATION, enlarging pituitary mass, visual defects secondary to compression of the OPTIC CHIASM, and elevated serum ACTH. It is caused by the expansion of an underlying ACTH-SECRETING PITUITARY ADENOMA that grows in the absence of feedback inhibition by adrenal CORTICOSTEROIDS, usually after ADRENALECTOMY.
Common name for the order Pleuronectiformes. A very distinctive group in that during development they become asymmetrical, i.e., one eye migrates to lie adjacent to the other. They swim on the eyeless side. FLOUNDER, sole, and turbot, along with several others, are included in this order.
Acquired or learned food preferences.
PLANTS, or their progeny, whose GENOME has been altered by GENETIC ENGINEERING.
A genus of mitosporic Phyllachoraceae fungi which contains at least 40 species of plant parasites. They have teleomorphs in the genus Glomerella (see PHYLLACHORALES).
A country spanning from central Asia to the Pacific Ocean.
It is used as an oxidizing and bleaching agent and as a disinfectant. (From Grant & Hackh's Chemical Dictionary, 5th ed)
Diseases of plants.
A plant genus in the LAURACEAE family. The tree, Persea americana Mill., is known for the Avocado fruit, the food of commerce.
Reproductive bodies produced by fungi.
A plant genus of the family POACEAE that contains allergen Dac g I.
A large family of narrow-leaved herbaceous grasses of the order Cyperales, subclass Commelinidae, class Liliopsida (monocotyledons). Food grains (EDIBLE GRAIN) come from members of this family. RHINITIS, ALLERGIC, SEASONAL can be induced by POLLEN of many of the grasses.
The fertilizing element of plants that contains the male GAMETOPHYTES.
A plant genus of the family ASTERACEAE. The POLLEN is one cause of HAYFEVER.
Immunosuppression by the administration of increasing doses of antigen. Though the exact mechanism is not clear, the therapy results in an increase in serum levels of allergen-specific IMMUNOGLOBULIN G, suppression of specific IgE, and an increase in suppressor T-cell activity.
A plant genus of the family TAXODIACEAE. Its POLLEN is one of the major ALLERGENS.
A plant genus of the family VERBENACEAE. Lippsidoquinone; TRITERPENES; SESQUITERPENES; and THYMOL have been found in this genus. Plant extracts have cytotoxic activity. It is sometimes called Mexican oregano but that confuses it with real oregano (ORIGANUM).
A plant species of the family APIACEAE. The stalks are a food source.
A mitosporic Ceratobasidiaceae fungal genus that is an important plant pathogen affecting potatoes and other plants. There are numerous teleomorphs.
Anethum graveolens L. is a plant species of the family APIACEAE. The leaves are considered as a spice (SPICES).
A plant genus of the family RUTACEAE. Members contain quinoline alkaloids.
A yellow fat obtained from sheep's wool. It is used as an emollient, cosmetic, and pharmaceutic aid.
The reproductive organs of plants.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
A plant genus of the family SALICACEAE. Balm of Gilead is a common name used for P. candicans, or P. gileadensis, or P. jackii, and sometimes also used for ABIES BALSAMEA or for COMMIPHORA.
The time period of daily exposure that an organism receives from daylight or artificial light. It is believed that photoperiodic responses may affect the control of energy balance and thermoregulation.
The pattern of GENE EXPRESSION at the level of genetic transcription in a specific organism or under specific circumstances in specific cells.
Annual cereal grass of the family POACEAE and its edible starchy grain, rice, which is the staple food of roughly one-half of the world's population.
A vine (Uncaria tomentosa) indigenous to the Amazon rainforest whose name is derived from its hook-like thorns. It contains oxindole alkaloids and glycosides and has many medicinal uses.
A plant family of the order Polygalales, subclass Rosidae class, Magnoliopsida that are mostly shrubs and small trees. Many of the members contain indole alkaloids.
