From Robert J. Spreitzer, University of Nebraska, June 2014
Phenotype: requires acetate, sensitive to light
This is an isolate of CC-4415 that has been cloned for better growth and transformation frequency. The T60-3 mutant was recovered by transformation of cwd arg7-8 mt- (CC-3395) with pARG7.8 (Gumpel et al. 1994), which caused the deletion of the Rubisco rbcS gene family (rbcS1 and rbcS2) (Khrebtukova and Spreitzer 1996). T60-3 lacks a cell wall and flagella, and cannot be crossed. This strain has been maintained with acetate medium in darkness since its isolation.
12/21/23 – This strain was found to be wild-type for the small subunit so is not a clonal isolate of T60-3.
