Fig. 5. (A) Survival rates of homozygous Csp^U1oc mutants (U1oc/U1oc), balanced siblings (U1oc/TM) and cDna1–, L8–, C27 or Ssp-transformed flies in null mutant background at 25°C culture temperature. In contrast to the wild-type CSP, L8 or C27, transgenic expression of SSP cannot rescue the short-life phenotype of null mutants and extends their life time only by ca. 20%. (B) Survival time for Clp– and Ssp– transformed flies are similar. Note the slightly increased survival time of Csp^U1/Csp^U1oc compared to Csp^U1oc/Csp^U1oc in A.
