DEFINITION

Classification: 435/483

Yeast is a host for the plasmid or episome:

(under subclass 476) Processes wherein the plasmid or episome

is introduced into a yeast.

(1) Note. A yeast is a unicellular fungus which is mono or oligonucleate and does not possess hyphae or an amoeboid morphology. This subclass thus does not include mycelial fungi and slime molds.

(2) Note. A fungus with a clearly defined yeast phase of growth and another phase, e.g., filamentous, etc., is classified here when the yeast phase is being transformed or recombined.

(3) Note. Examples of host genera proper for this subclass are Saccharomyces, Schizosaccharomyces, Kluyveromyces, Pichia, Hansenula, and Torulopsis.
