Influence of DNA repair/recombination proteins on retrosequence formation

^aTLC1 indicates the BY4742 strain background, and EST2 indicates the GRF167 strain background. Two or more independent transformants were analyzed for each mutation.

^bSets of triplicate cultures tested.

^cWhen no His⁺ prototrophs were obtained, the frequency was listed as less than the value that would have been obtained if one His⁺ prototroph had formed. Such frequency values were ranked as if they were equal to their maximum frequency value for determining the range and median.

^dNormalized to a wild-type telomerase-positive strain, a tlc1Δ strain, or an est2Δ1 strain, as appropriate.

(*) P < 0.025; (**) P < 0.01; (***) P < 0.001.
