The phase of declining growth rate, following the linear phase and preceding the stationary phase in most batch-suspension cultures.<i> See</i> growth phases.
Industry:Biotechnology
The phase state in which a dominant (or wild-type) allele at one locus and a recessive (or mutant) allele at a second locus occur on the same chromosome. Also called trans configuration.
Industry:Biotechnology
The phase state in which either two dominant or two recessive alleles of two different genes occur on the same chromosome. Also called cis configuration. <i>cf</i> repulsion.
Industry:Biotechnology
The phenomena that, after a number of sub-cultures, cells can grow, without the addition of specific factors, such as no longer needing exogenous growth regulators in the tissue culture medium. Such cells are autonomous.
Industry:Biotechnology
The phenomenon by which the secretion of chemicals, such as phenolic and terpenoid compounds, by a plant inhibits the growth or reproduction of other plant species with which it is competing.
Industry:Biotechnology
The phenomenon of inhibition of growth of lateral (axillary) buds in a plant by the presence of the terminal (apical) bud on the branch, due to auxins produced by the apical bud.
Industry:Biotechnology
The phenomenon whereby a number of genes at different loci (which may be polygenes) can act together to produce a single effect.
Industry:Biotechnology
The phosphate group that is attached to the 5´ carbon atom of a sugar (ribose or deoxyribose) of the terminal nucleotide of a nucleic acid molecule.
Industry:Biotechnology
The plane of cell wall orientation or cell division parallel to the surface of the organ. <i>cf</i> anticlinal.
