Table 2. Quantification of large interspaces (gaps) between VPCs in C. elegans and O. tipulae plexin mutants, as determined by MH27 staining.

Species	Strain	Phenotype	Number of animals
C. elegans	N2	WT	> 50
C. elegans	ST54: plx-1(nc37)	WT	37
		Gap P7.p–P8.p	13
		Gap P6.p–P7.p	6
		Gaps P4.p–P5.p and P6.p–P7.p	1
O. tipulae	CEW1	WT	> 30
O. tipulae	JU108: Oti-plx-1(mf78)	WT	35
		Gap P4.p–P5.p	2
		Gaps P4.p–P5.p and P7.p–P8.p	1

“Gap P7.p–P8.p” refers to a gap between the P7.p and P8.p cells. WT, wild-type.
