Fig. (2) Tolerance to desiccation-rehydration of 90 mutants of K. variicola T29A 18 days after the beginning of desiccation (DABD). The upper dotted line denotes the BSR before desiccation. The gray line represents the BSR of the wild strain in the assay, while the points denote the BSR 18 DABD for each of the 90 mutants evaluated. Some sensitive mutants are exemplified.
