In mammals, the process of escape of the ovum (egg cell) from the ovary.
Industry:Biotechnology
In orchids, seeds contain an unorganized embryo comprising only a few hundred cells. During seed germination this embryo forms a tuberous structure, called a protocorm, from which develops a complete plant. In cultures, vegetative parts of several orchids form round, smooth protocorms which may be multiplied indefinitely or induced to regenerate a whole plant.
Industry:Biotechnology
An early, cultivated form of a crop species, evolved from a wild population.
Industry:Biotechnology
Defined in the International Undertaking on Plant Genetic Resources as a collection of seed stock or vegetative propagating material (ranging from tissue cultures to whole plants) held for long-term security in order to preserve the genetic variation for scientific purposes and as a basis for plant breeding as multiplication and evaluation. <i>cf</i> active collection.
Industry:Biotechnology
Defined in the International Undertaking on Plant Genetic Resources as a collection which complements a base collection (q.v.) and is a collection from which seed samples are drawn for distribution, exchange and other purposes such as multiplication and evaluation.
Industry:Biotechnology
In plant pathology, strains of bacteria causing disease in specific plant cultivars.
Industry:Biotechnology
In plants, the inability of the pollen to fertilize ovules (female gametes) of the same plant.
Industry:Biotechnology
In prokaryotes, a cell that has been genetically altered through the uptake of foreign DNA. In higher eukaryotes, a cultured cell that has acquired a malignant phenotype.
Industry:Biotechnology
In quantitative genetics, the average of the phenotypes of two mates.
Industry:Biotechnology
In quantitative genetics, the part of the deviation of an individual phenotype from the population mean that is due to the additive effects of alleles. In practical terms: if an animal is mated with a random sample of animals from a population, that animal's breeding value for a certain trait is twice the average deviation of its offspring from the population mean for that trait.
