Germ line cells
Cells that produce gametes

Germ line gene therapy
The delivery of a gene or genes to a fertilized egg or an early embryonic cell. The transferred gene(s) is present in all or some of the nuclei of the cells of the mature individual, including possibly the reproductive cells, and alters the phenotype of the individual that develops.

GMP
(good manufacturing practice) See GLP /GMP.

Germ line
A lineage of "generative" cells (= germ track) ancestral to the gametes (sperm and egg cells proper) which, during the development of an organism (animal or plant), are set aside as potential gamete forming tissues. These ancestral cells, together with the gametes, are called germ cells, as opposed to somatic cells. Location, nature and time of formation of potential gamete forming tissues are species specific, and may vary greatly from one species to another.

Germplasm
1. The genetic material that forms the physical basis of hereditary and which is transmitted from one generation to the next by means of the germ cells. 2. An individual or clone representing a type, species or culture, that may be held in a repository for agronomic, historic or other reasons.

Gestation
The period in animals bearing live young (especially mammals) from fertilization of the egg to birth of the young (parturition). GH See growth hormone.

Gibberellins
Plant growth regulators involved in elongation, enhancement of flower, fruit and leaf size, germination, vernalization and other processes.

Glycolysis
(Gr. glycos, sugar (sweet) + lysis, dissolution) Sequence of reactions that converts glucose into pyruvate, with the concomitant production of A TP.

GM food
Food that comprises, in whole or in part, material that has been modified by the application of recombinant DNA technology.

GMO
See genetically modified organism.

Gland
A group of cells or a single cell in animals or plants that is specialized to secrete a specific substance. In animals, there are two types of glands: endocrine glands discharge their products directly into the blood vessels; exocrine glands secrete through a duct or network of ducts into a body cavity or onto the body surface. In plants, glands are specialized to secrete certain substances produced by the plant. The secretions may be retained within a single cell, or secreted to the outside.

Global warming
The long term warming of the plant due to increases in greenhouse gases which trap reflected light preventing it from exiting to space

GLP
(Good Laboratory Practice); GMP (Good Manufacturing Practice) They are codes of practice designed to reduce to a minimum the chance of accidents which could affect a research project or a manufactured product. The GLP and GMP prescriptions are quite voluminous, but boil down to a few key points. The essential point of both GLP and GMP is that everything is recorded, and that only established procedures are used and by people who have been trained to use them. glucocorticoid .A steroid hormone that regulates gene expression in higher animals.
