The absence of Elongator does not affect MT dynamics in fission yeast.

A: Serial dilution assay of the wild type, elp3∆, cut7–24, cut7–24 elp3∆, cut7–22 and cut7–22 elp3∆ strains incubated for 3 days at the indicated temperatures. B: Selected kymographs showing interphasic MT dynamics in wild type, ppe1∆, elp3∆ and elp3-YY527AA cells expressing GFP-Atb2, showing the inverted green channel in a grey scale. Scale bar: 5 μm. C: Plot showing MT growth rate of the indicated strains expressing GFP-Atb2 (n for wild type: 74; n for ppe1∆: 87; n for elp3∆: 79; n for elp3-YY527AA: 79). Statistical differences were determined using a T-test (wt vs. ppe1∆, p = 0.409; wt vs. elp3∆, p = 0.374; wt vs. elp3-YY527AA, p = 0.001). D: Plot showing MT catastrophe rate of the indicated strains expressing GFP-Atb2 (n for wild type: 95; n for ppe1∆: 73; n for elp3∆: 82; n for elp3-YY527AA: 88). Statistical differences were determined using a T-test (wt vs. ppe1∆, p = 0.054; wt vs. elp3∆, p = 0.003; wt vs. elp3-YY527AA, p = 0.294). E: Plot showing MT dwelling time at the cell end of the indicated strains expressing GFP-Atb2 (n for wild type: 63; n for ppe1∆: 67; n for elp3∆: 67; n for elp3-YY527AA: 65). Statistical differences were determined using a T-test (wt vs. ppe1∆, p = 0.931; wt vs. elp3∆, p = 0.500; wt vs. elp3-YY527AA, p = 0.667). F: Maximum intensity projections from confocal time lapse images of wild type cells expressing mCherry-Atb2 and Elp3 or Elp4 fused to GFP. The upper series shows the magenta (mCherry-Atb2) and green (Elp3-GFP or Elp4-GFP) merged channels. The bottom series shows the inverted green channel in a grey scale. Time 0 corresponds to mitotic entry. The dashed line represents the cell contour. Scale bar: 2 μm. G: Western-blot analysis of SDS PAGE of Elp3-GFP and Elp4-GFP from the strains shown in C. (XLSX)
