From Biology-Online Dictionary
Jump to: navigation, search

pili, sex

filamentous or elongated proteinaceous structures which extend from the cell surface in gram-negative bacteria that contain certain types of conjugative plasmid. These pili are the organs associated with genetic transfer and have essential roles in conjugation. Normally, only one or a few pili occur on a given donor cell. this preferred use of pili refers to the sexual appendage, to be distinguished from bacterial fimbriae (fimbriae, bacterial), also known as common pili, which are usually concerned with adhesion.
