Poaceae
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.
Brachiaria
Bambusa
A plant genus of the family POACEAE. Young shoots are eaten in Asian foods while the stiff mature stems are used for construction of many things. The common name of bamboo is also used for other genera of Poaceae including Phyllostachys, SASA, and Dendrocalamus.
Sorghum
Gametogenesis, Plant
Poa
A plant genus of the family POACEAE that contains the Poa p Ia allergen and allergen C KBGP.
Panicum
Genome, Chloroplast
The genetic complement of CHLOROPLASTS as represented in their DNA.
Typhaceae
DNA, Chloroplast
Deoxyribonucleic acid that makes up the genetic material of CHLOROPLASTS.
Lolium
Common member of the Gramineae family used as cattle FODDER. It harbors several fungi and other parasites toxic to livestock and people and produces allergenic compounds, especially in its pollen. The most commonly seen varieties are L. perenne, L. multiflorum, and L. rigidum.
Polyploidy
Chromosomes, Plant
Brachypodium
A plant genus in the family POACEAE. Brachypodium distachyon is a model species for functional genomics studies.
Genome, Plastid
The genetic complement of PLASTIDS as represented in their DNA.
Sasa
Oryza sativa
Eleusine
Pennisetum
Angiosperms
Members of the group of vascular plants which bear flowers. They are differentiated from GYMNOSPERMS by their production of seeds within a closed chamber (OVARY, PLANT). The Angiosperms division is composed of two classes, the monocotyledons (Liliopsida) and dicotyledons (Magnoliopsida). Angiosperms represent approximately 80% of all known living plants.
Zea mays
Apomixis
Setaria Plant
A plant genus of the family POACEAE. The small pointed seeds are grown for hay in North America and western Europe and important as food in China and other Asian countries.
Evolution, Molecular
Bromus
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.
Neotyphodium
The anamorphic form of the fungus EPICHLOE. Many Neotyphodium species produce ERGOT ALKALOIDS.
Inflorescence
A cluster of FLOWERS (as opposed to a solitary flower) arranged on a main stem of a plant.
Agropyron
Plant Weeds
Species Specificity
The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
Ecotype
Geographic variety, population, or race, within a species, that is genetically adapted to a particular habitat. An ecotype typically exhibits phenotypic differences but is capable of interbreeding with other ecotypes.
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)
Triticum
Plastids
Introduced Species
Non-native organisms brought into a region, habitat, or ECOSYSTEM by human activity.
Sequence Analysis, DNA
Endophytes
An endosymbiont that is either a bacterium or fungus living part of its life in a plant. Endophytes can benefit host plants by preventing pathogenic organisms from colonizing them.
Microsatellite Repeats
Gene Duplication
Processes occurring in various organisms by which new genes are copied. Gene duplication may result in a MULTIGENE FAMILY; supergenes or PSEUDOGENES.
Synteny
The presence of two or more genetic loci on the same chromosome. Extensions of this original definition refer to the similarity in content and organization between chromosomes, of different species for example.
Festuca
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Rhizome
Seeds
Hybridization, Genetic
Genetic Markers
Genetic Loci
Specific regions that are mapped within a GENOME. Genetic loci are usually identified with a shorthand notation that indicates the chromosome number and the position of a specific band along the P or Q arm of the chromosome where they are found. For example the locus 6p21 is found within band 21 of the P-arm of CHROMOSOME 6. Many well known genetic loci are also known by common names that are associated with a genetic function or HEREDITARY DISEASE.

Random Amplified Polymorphic DNA Technique
Technique that utilizes low-stringency polymerase chain reaction (PCR) amplification with single primers of arbitrary sequence to generate strain-specific arrays of anonymous DNA fragments. RAPD technique may be used to determine taxonomic identity, assess kinship relationships, analyze mixed genome samples, and create specific probes.
Chloroplasts
Plant cell inclusion bodies that contain the photosynthetic pigment CHLOROPHYLL, which is associated with the membrane of THYLAKOIDS. Chloroplasts occur in cells of leaves and young stems of plants. They are also found in some forms of PHYTOPLANKTON such as HAPTOPHYTA; DINOFLAGELLATES; DIATOMS; and CRYPTOPHYTA.

Photosynthesis
The synthesis by organisms of organic chemical compounds, especially carbohydrates, from carbon dioxide using energy obtained from light rather than from the oxidation of chemical compounds. Photosynthesis comprises two separate processes: the light reactions and the dark reactions. In higher plants; GREEN ALGAE; and CYANOBACTERIA; NADPH and ATP formed by the light reactions drive the dark reactions which result in the fixation of carbon dioxide.
