Septins enhance the baz⁴ embryonic cuticle defect. (A) Embryonic cuticles were scored according to six categories; 1 is the least severe with wild-type cuticle and 6 is the most severe with only scraps of cuticle. (B) Zygotic baz⁴ males are expected to be embryonic lethal and have varying degrees of defective cuticle (control). When the mother is heterozygous for Sep2², Sep5², or pnut^XP, the cuticle defect of zygotic baz⁴ males is more severe (Mann-Whitney U-test p-values for each mutant vs. control are 0.000217, 0.0129, and 2.28E-08, respectively). Sep2² and Sep5² are not significantly different from each other in their enhancement of baz⁴ (p-value = 0.158), whereas pnut^XP has a more severe enhancement compared to Sep2² (p-value = 0.011) or Sep5² (p-value = 0.000179).
