Schematic indicates the overall domain structure of the Drosophila family members, Kahuli, Snail, Escargot, Wornoi, CG12605 and Scratch. A’. Phylogenetic tree indicating the relationship of between Kah and the members of the Snail/Scratch family. B. Violin plots from scRNA-seq of wild-type embryos indicates Kah transcript is expressed in the embryonic VM and SM. C. Violin plots from scRNA-seq analysis of FACS <t>sorted</t> <t>Hand-GFP</t> expressing cells reveals expression of Kah mRNA in visceral, but not cardiac, mesoderm. D. Kah transcripts are abundant in SM and VM during embryogenesis, with increased expression levels in the visceral founder cell (FC) row. FCM, fusion competent myoblasts; sm, somatic musculature; vm, visceral musculature. E. Ectopic expression of jeb results in an increase of Kah expression in visceral FCMs. Conversely, animals devoid of Jeb/Alk signalling ( jeb weli mutants) lack the strong FC-specific Kah expression in the VM while SM expression remains unaltered. F-G’. A Kah.GFP gene duplication construct can be detected from stage 10 embryos in the VM, with no clear distinction between FCs (marked by rp298-lacZ, red, inset depicts a close-up in LUT colors) and FCMs. Lateral view (F, F’), dorsal view (G, G’).

A. Schematic overview of the newly generated Kah alleles: Kah Cterm.OLLAS , Kah ΔATG and Kah ΔZnf , together with the Kah f06749 PiggyBac insertion allele. B. Stage 10 embryos exhibit FC-specific expression of Org-1 (red) and HandC-GFP (green) FC markers. Dorsal views. C. Wild-type embryos at stage 16 are characterized by three midgut constrictions while Kah mutants fail to form the first midgut constriction. Kah mutants express Wg and dpp at levels comparable with control ( w 1118 ) embryos. Dorsal views. D. Quantification of the midgut constriction phenotype observed in C. E. pnt Δ88 mutants display a midgut constriction phenotype similar to that observed in Kah mutants. Dorsal views. F. Kah mutants display abnormal organisation of midgut musculature, visualized with the nuclear HandC-GFP reporter FC markers (green). Lateral views. G. Quantification of the number of nuclei present in wild-type ( w 1118 ) and Kah mutants.
