Deletion removing the translation initiation codon.
The number of eve-positive pericardial cells is reduced in mutant embryos. There is a severe reduction and disorganisation of somatic muscles; LT3 frequently appears to be transformed into LT4.
Df(3R)Exel6157/+, ponP65 has cardiogenic mesoderm phenotype
Df(1)CHES-1-like1/+, ponP65 has cardiogenic mesoderm phenotype
ponP65/+ ; Df(3R)Exel6157/+ double heterozygous embryos show asymmetric cell division defects in "svp" cardiac progenitor cells that are significantly more severe than the additive effects of each of the two single heterozygotes. Defects in the symmetric cell divisions that give rise to the tin-expressing cardial cells in the double heterozygotes are not significantly different from the additive effects of each of the two single heterozygotes.
