Duration of expression for vulval gene expression markers

Reporter	Cells	Duration of GFP expression	Comments
egl-17::gfp	C, D	L4.2 to L4.9*	[34]
cdh-3::cfp	C, D, E, F	L4.1 to L4.9*	[35] Variable expression in L4.1; consistent in later sub-stages
ceh-2::gfp	B1, B2, C	L4.1 to L4.9*	[4] Variable expression in all sub-stages; low level of expression in B2, C from L4.1 to L4.7
daf-6::cfp	E, F	L4.3 to L4.9*	[36] Expression in E variable in L4.3 and L4.4, consistent in later sub-stages; expression in F variable throughout
B0034.1::gfp	E, F	No expression in L4	[4] Expressed in adults only
F47B8.6::gfp	C, D, E, F	No expression in L4	[4] Expressed in adults only
egl-26::gfp	B1, B2	L4.4 to L4.9*	[32]
	E	L4.2 to L4.9*
egl-38::gfp	D, E, F	L4.1 to L4.7	[22] Only reporter in this study where expression was obviously turned off during L4.
best-13::gfp	B1, B2, C, D, E	L4.1 to L4.9*	[37] Variable expression possibly due to loss of extrachromosomal array

*Expression of these reporters persist into the adult stage
