Project description:Our study focuses on understanding the early transcriptional changes taking place during the divergence of the adult muscle precursors that give rise to indirect flight muscles and direct flight muscles in Drosophila. We analyzed the heterogenous cell population of the adult muscle precursors by scRNA-seq and build an integrated single-cell reference atlas. We addressed the differences among muscle-type and different cell state during myoblast differentiation. Also, our dataset includes the transcriptional profile of the epithelial cells localized in the presumptive hinge and notum of third instar larval wing discs. In addition we studied the functional relevance of Amalgam in flight muscle development by depleting Ama expression specifically in the adult muscle precursors. We determined the transcriptional changes and perturbations in AMP cell identity upon Ama knockdown.

Project description:Muscle development and diversity require a large number of spatially and temporally regulated events controlled by transcription factors (TFs). Drosophila has long stood as a model organism to study myogenesis due to the highly conserved key TFs involved at all stages of muscle development, from specification to differentiation. While many studies focused on the diversification of Drosophila larval musculature, how distinct adult muscle types are generated is much less characterised. Here, we identify a novel essential regulator of Drosophila thoracic flight muscle development, the Hox TF Antennapedia (Antp). Correcting a long standing misconception that flight muscle development occurs without the input of Hox TFs, we show that Antp intervenes at several stages of adult flight muscle development, from the establishment of the progenitor pool in the embryo to myoblast differentiation in the early pupa. Furthermore, the precisely regulated clearance of Hox at the pupal stage in the developing indirect flight muscle fibers is required to allow for stretch-activated fibrillar muscle fate diversification that sets these flight muscles apart from all other adult tubular muscle types. This SuperSeries is composed of the SubSeries listed below.

Project description:In Drosophila, fibrillar flight muscles (IFMs) enable flight, while tubular muscles mediate other body movements. Here, we use RNA-sequencing and isoform-specific reporters to show that spalt major (salm) determines fibrillar muscle physiology by regulating transcription and alternative splicing of a large set of sarcomeric proteins. We identify the RNA binding protein Arrest (Aret, Bruno) as downstream of salm. Aret shuttles between cytoplasm and nuclei, and is essential for myofibril maturation and sarcomere growth of IFMs. Molecularly, Aret regulates IFM-specific transcription and splicing of various sarcomeric targets, including Stretchin and wupA (TnI), and thus maintains muscle fiber integrity. As Aret and its sarcomeric targets are evolutionarily conserved, similar principles may regulate mammalian muscle morphogenesis. 9 samples from Drosophila melanogaster were analyzed in duplicate: control dissected wildtype flight muscle at 30h APF, 72h APF and 0 day adult, jump muscle and whole leg from 1d adult and RNAi/mutant conditions for salm (1d flight muscle) and aret (30h, 72h and 1d flight muscle)

Project description:To complement our existing data on developmental gene expression changes in flight muscle (IFM) development in Drosophila (GSE107247, GSE63707), we performed mRNA-Seq on dissected leg samples at three stages during pupal development (30, 50 and 72h APF). We further sequenced an additional timepoint at 24h APF for RNAi knockdown of aret (Bru1) in flight muscle. Comparison of splicing and expression profiles of sarcomeric genes allowed us to identify muscle-type specific differences in gene and isoform expression between fibrillar flight muscle and tubular leg muscle. We can further trace the dynamics of exon usage in sarcomere genes across the developmental timecourse, allowing us to identify events the switch during muscle differentiation and maturation.
