Cytoplasmic inheritance
Hereditary transmission dependent on the cytoplasm or structures in the cytoplasm rather than the nuclear genes; extrachromosomal inheritance. Thus, plastid, characteristics in plants are inherited by a mechanism independent of nuclear genes.

Cytoplasmic male sterility
Genetic defect due to defective functions of mitochondria in the pollen. Fertilization will not occur. Exploited in certain plant breeding strategies, such as F1-hybrid maize cultivars.

Cytoplasmic organelles
Discrete sub-cellular structures located in the cytoplasm of cells; these allow division of labour within the cell.

Cytosine
A pyrimidine base found in DNA and RNA.

Cytosol
The fluid portion of the cytoplasm, i.e. the cytoplasm minus its organelles.

Cytotoxic
T cell see killer T cell.
