title: Isolation of suppressor sensitive mutants in the Ai gene of phage lambda.
abstract: Previous experiments have shown that mutations in the Ai gene can suppress the growth defect of lambda N- phages. Many temperature resistant derivatives of phage lambdatsN9 have been isolated and among these 5 have been found which are Ai- and have an amber suppressible behaviour. These mutants can help in defining the role of the Ai gene in phage lambda development.
