syIs20 [gpa-1::lacZ + dpy-20(+)] V. Him. p-Vul. Abnormal secondary vulva lineage defect in 10% of animals. Reduced brood size as well as other pleiotropic defects. Males have ray defect (cannot mate) and SPD sheath to neuron transformation, which can be visualized by lacZ staining in syIs20 [gpa-1::lacZ] background: 1 cell per spicule stains in WT (the SPD neuron) whereas in hmg-1.2(sy549), 2 cells per spicule stain. sy549 previously called son-1. Do not distribute this strain; other labs should request it from the CGC.
