Nucleotide substitution: C2563T.
The base pair transition from C to T at position 2563 of the genomic sequence introduces a stop codon near the end of the third exon.
Approximately 14.1% of cicfet-U6/cicBA53 exhibit a moderate-severe eggshell phenotype. The dorsal midline is expanded and the appendages are broader and positioned laterally and exhibit a pronounced ventral collar of ectopic appendage-like material. The dorsalmost region remains free of appendage material.
Approximately 85.9% of cicfet-U6/cicBA53 exhibit a severe eggshell phenotype. The dorsal midline is expanded and the appendages are broader and positioned laterally and exhibit a pronounced ventral collar of ectopic appendage-like material, along with small anterior projections.
cicfet-U6/cicBA53 has dorsal appendage phenotype, suppressible by mirr6D1
Approximately 0.5% of cicfet-U6/mirr6D1 cicBA53 females exhibit a moderate eggshell phenotype. The dorsal midline is expanded and the appendages are broader and positioned laterally and exhibit a ventral collar of ectopic appendage-like material. The dorsalmost region remains free of appendage material. Approximately 32.6% of cicfet-U6/mirr6D1 cicBA53 females exhibit a severe eggshell phenotype (compared to 85.9 in the heterozygote). The dorsal midline is expanded and the appendages are broader and positioned laterally and exhibit a pronounced ventral collar of ectopic appendage-like material, along with small anterior projections.There is an increase in the weak phenotype, and a decrease in the severe phenotype compared to the cicBA53/cicfet-U6 mutant, indicating that mirr6D1 suppresses the cicBA53/cicfet-U6 phenotype.
