rhoL68/rho7M43 mutant embryos exhibit cardioblast (CB) patterning defects, and a significantly decreased number of cardioblasts, namely of generic cardioblasts, leading to a lower generic CBs:ostial CBs ratio than the typical 4:2 ratio. These embryos also exhibit a strong decrease in the number of odd pericardial cells, although even pericardial cells are unaffected, as compared to controls.
Defect in embryonic PNS development: loss of two lateral and one ventral Ch neurons.
