Studies on the In Vitro Assembly of Bacteriophage φ80 and φ80-Lambda Hybrids

Abstract

Suppressor-sensitive (sus) mutants of bacteriophage φ80 defective in late functions were classified, by means of in vitro assembly tests, into two complementation groups: head donors and tail donors. Each group of mutants was subdivided, by means of two-factor crosses, into six cistrons. Deletion mapping revealed clustering of tail and also of head cistrons. The two clusters were located in the left arm of vegetative φ80 (the tail specifying cluster being distal). In vitro cross complementation between φ80 and lambda sus mutants revealed that whereas lambda heads could quite efficiently bind φ80 tails to form viable phage, the union of φ80 heads and lambda tails was very much less efficient. Deletion mapping of the φ80 sus mutants, using both φ80 and iφ80hλ deletion lysogens indicated congruent gross gene arrangement in the two related bacteriophages.
