Source Data for Table 1[LSA-2018-00054_SdataT1.xlsx]

  • Source data are available for this table.

  • Image series were collected at 3- to 4-s intervals for 10 min and microtubule lengths were measured at each time point. Values shown are the medians, with 95% CIs in parentheses, of pooled data from at least four separate experiments.

  • * P < 0.05, compared with wild type, based on the Mann–Whitney U test. Number of aMTs measured for each genotype: wild type, n = 45; tub2-430∆, n = 51; tub2-438∆, n = 34; and tub2-polyQ, n = 65.
