Heat shock induces nuclear GFP expression in the somatic gonad and nuclear mCherry expression elsewhere. Constitutive expression of diffusible mNeonGreen in the somatic gonad can mask GFP::HIS-58 signal. Might carry unc-119(ed3) or unc-119(ed9) III.

hyEx167 [4.5kb aff-1p::GFP transcriptional fusion + rol-6(su1006)]. Shows cytoplasmic GFP expression in embryonic hyp5. In L1 hermaphrodite larva, aff-1::GFP is expressed in pharyngeal muscle 3 and 5, in sheath cells of chemosensory neurons, and in tail neurons. In L3 hermaphrodites, the transgene is expressed in the anchor cell; this expression proceeds in L4 along with expression in the utse cells, the seam cells and cells of vulval rings A and D. In adults, aff-1::GFP is expressed in the sheath cells of chemosensory neurons and in head interneurons, uterus toroids 2 and 4, in the vulva VulD, utse, and seam cells. Worms of hyEx167 are slightly Egl. Maintain by picking Rollers.

A 1.2 kb deletion in aff-1 (C44B7.3) which introduce stop codon after alanine 47. AFF-1 is a type I membrane protein necessary and sufficient for specific cell fusion events during embryonic and larval development. Temperature sensitivity was not detected. At 20° the fusion of hyp5 in the embryo does not occur as well as anchor cell (AC) fusion, vulval cells fusion of the A and D rings and the terminal fusion between the seam cells late in L4. 6% L1 rod-like lethal and 0% embryonic lethal. Adults are completely Egl, and partially Unc, Pvl. In addition, only 2% of AC in the mutant worms undergo fusion. These animals give very low brood size (16 progeny per worm) and 3.4% of the worms are sterile. This strain gives very small brood size and hence grows slowly. Originally from Shohei Mitani, Tokyo Women's Medical College, Tokyo, Japan.

Slow postembryonic development. Reduced brood size. Previously known as pep-2. [NOTE: the genotype of this strain was previously incorrectly annotated as lg1601. The correct allele name is lg601.] Reference: Meissner B, et al. J Biol Chem. 2004 Aug 27;279(35):36739-45.
