Anita Lardans, Boynton-Gillham laboratory, Duke University, 1999

Phenotype: requires acetate; herbicide resistant (atrazine, bromacil, metribuzin)

This strain was derived from a cross of CC-3382 “Leu suppressor mt+” (no longer in the collection) to CC-124 wild type mt-. The submission notes for CC-3766 describe it as psbA A251L. We believe that this is the same site-directed A251L mutation as is present in CC-3389, but that CC-3766 does not have the silent T247C mutation that is also in that strain. Please see CC-3389 for more information on this mutation.

From John Davies, Iowa State University, August 2000

Phenotype: altered sulfur metabolism

Derived from transformation of CC-425 with plasmid pJD76, subsequently crossed with CC-2677 (nit1-305).

This strain does not express arylsulfatase activity when grown under sulfur-deficient conditions. As a group, the sac1 mutants fail to accumulate arylsulfatase or the proteins of the high-affinity sulfate transport system when transferred to sulfur-deficient medium. They are also unable to decrease photosynthesis under these conditions, with the result that they die when cultured in the light under sulfur-limiting conditions.
