nonconjugative plasmid


Also found in: Encyclopedia.

non·con·ju·ga·tive plas·mid

a plasmid that cannot effect conjugation and self-transfer to another bacterium (bacterial strain); transfer depends upon mediation of another (and conjugative) plasmid.

A plasmid that cannot effect conjugation and self-transfer to another bacterium (bacterial strain); transfer depends on mediation of another (and conjugative) plasmid.

nonconjugative plasmid

a non-transmissible PLASMID, which cannot mediate CONJUGATION. Non-conjugative plasmids lack transfer (tra) genes, which are present on CONJUGATIVE PLASMIDS. However, they can sometimes be co-transferred with appropriate CONJUGATIVE PLASMIDS, when co-residing in the same cell. Usually smaller than CONJUGATIVE PLASMIDS.
