The posterior region of the heart tube is abnormally dilated in mutant embryos.
Some germ cells fail to move off the midgut and do not associate with somatic gonadal precursor cells in the mesoderm at stages 11-12 in mutant embryos.
Primordial germ cell migration is disrupted. Some PGCs fail to migrate from the endoderm to the mesoderm. Many of those that do fail to associate with the gonadal mesoderm and remain scattered throughout the embryo. Gonadal mesoderm development proceeds normally, as does development of the nervous system and the trachea.
Hmgcrclb1 is a suppressor of adult brain phenotype of SNF4Aγloe
The germ cell migration defects of slamwaldo1 Hmgcrclb1 double mutants are stronger than either single mutant; no germ cells move off the midgut in double mutant embryos.
Strong allele.
