Homozygous. No obvious phenotype by dissecting scope. Do not distribute this strain; other labs should request it from the CGC.

Low percent sterile, more sperm than WT, delayed oogenesis, larger broods than WT. PCR amplify: WT band is about 3 kb, deletion band is about 1.2 kb. Oligos used: outer: 201A and 202S; inner: 203A and 204S. Do not distribute this strain; other labs should request it from the CGC.

Heterozygotes are non-Dpy with a green pharynx and a WT germ line. fbf-1 fbf-2 homozygotes are non-Dpy, GFP-, and have small germ lines containing only sperm. mIn1[mIs14 dpy-10(e128)] homozygotes are Dpy, GFP+ and have a WT germ line. Do not distribute this strain; other labs should request it from the CGC.

qIs24 [lag-2p::GFP]. Maintain by picking individual animals with green DTCs and green pharynx and scoring offspring for Fems and Fbfs. fem-3 is not well balanced by qIs24. fbf-1 fbf-2 homozygotes are germline proliferation defective and make only sperm. fem-3 homozygotes make only oocytes. fbf-1 fbf-3; fem-3 proliferates more than fbf-1 fbf-2 and makes only oocytes; also Muv. qIs24 contains lag-2::GFP; Distal Tip Cells are green; homozygotes are Rollers and heterozygotes Roll weakly. mIn1 is Dpy and GFP+ in the pharynx. Do not distribute this strain; other labs should request it from the CGC.

To maintain, check individual fertile worms for both Sep and Fog offspring. sep-1 homozygotes are sterile at 20C and 25C (Sterile and Unc at 25C), and mostly normal at 15C. fog-1; fbf-1 fbf-2 homozygotes have small germ lines and are often Muv. Best to maintain at 25C for scoring. Do not distribute this strain; other labs should request it from the CGC.

qSi364 [3xFLAG::fbf-2(R7/R8 loop deletion) + unc-119(+)] IV. Single-copy MosSCI insertion into oxTi177 IV. R7/R8 loop deletion removes a critical protein-to-protein interface. qSi364 is phenotypically wild-type on its own, but Mog when crossed into fbf-1(ok91) fbf-2(q704) background.
