Bacteriophage [var phi]X174 temperature-sensitive and nonsense mutations in eight cistrons were mapped by using two-, three-, and four-factor genetic crosses. The genetic map is circular with a total length of 24 × 10−4wt recombinants per progeny phage. The cistron order is D-E-F-G-H-A-B-C. High negative interference is seen, consistent with a small closed circular deoxyribonucleic acid molecule as a genome.

For the initial idea to study genetic recombination in [phi]X174, we are grateful to Paul Howard-Flanders. In addition, we thank Gloria Davis and Kay Burroughs for excellent technical assistance, Alma J. Shafer for performing several complementation tests, and the "[phi]X174 group" for critical comments on this manuscript before publication. We would also like to acknowledge a stimulating discussion about "hairpin" DNA configurations with R. Shekman.|
