Expression Pattern :

Pattern  We examined NHR-23::GFP expression over the course of the 4th larval stage, as vulva morphology allows for more precise sub-staging (Mok et al., 2015). NHR-23::GFP expression was first detectable in L4.1 larvae, peaked in expression from L4.2-L4.3, disappeared in the vulva by L4.5 and in the head by L4.6, and then remained undetectable, similar to what the observations of Kinney et al. (2023) of NHR-23::mScarlet. Primary Identifier  Expr16585

4 Life Stages

Remark Definition Other Name Public Name Primary Identifier
  The fourth sub-stage of the L4 larva. vulFs have separated and the apex of the lumen is flat and capped by the anchor cell. The uterine lumen starts to form. At 20 Centigrade: 38.1 hours after hatching, 4.1 hours from the L3-to-L4 molt. L4.3 larva Ce WBls:0000686
  The third sub-stage of the L4 larva. All vulval cells complete migration. vulA, vulC, and vulD undergo cell fusion. The vulval lumen has widened and a prominent kink has formed between vulC and vulD. The uterine lumen has not started to form. At 20 Centigrade: 36.8 hours after hatching, 2.8 hours from the L3-to-L4 molt. L4.2 larva Ce WBls:0000685
  The fifth sub-stage of the L4 larva. utse is visible as a thin layer separating the vulval and uterine lumens. 'Fingers' are formed at the sides of the vulva next to vulB1 and vulB2. The uterine lumen is fully distended. At 20 Centigrade: 39.0 hours after hatching, 5.0 hours from the L3-to-L4 molt. L4.4 larva Ce WBls:0000687
  The second sub-stage of the L4 larva. The inner cells of the vulva have finished migrating and have formed toroids, but have not fused. vulC and vulF have divided and a narrow lumen has formed. At 20 Centigrade: 35.1 hours after hatching, 1.1 hours from the L3-to-L4 molt. L4.1 larva Ce WBls:0000684
