Conditional-lethal mutations that suppress genetic defects in morphogenesis
by altering structural proteins
Proc. Natl. Acad. Sci., USA
Vol 72, pp 2738-2742, 1975

These authors describe what might be called "synthetic vitality", a
phenomenon  closely related to "synthetic lethality".  The paper describes
the isolation of phage P22 conditional-lethal mutations that suppress
missense lethal mutations in other genes.  "...Suppressor analysis ought to
be especially useful for investigating proteins that engage in strong
noncovalent interactions with one another."
