AbstractIn situ hybridization (ISH) has played a crucial role in developing a spatial transcriptomic understanding of emerging model organisms in the past, but advancing high-throughput RNA-sequencing (RNA-seq) technology has pushed this method into the shadows, leading to a loss of data resolution. This shift in research towards the exclusive use of RNA-seq neglects essential considerations for transcriptomic studies including the spatial and temporal expression of transcripts, available budget, experimental design needs, and validation of data. A synergy of spatiotemporal transcriptomic techniques is needed, using the bulk and unbiased analysis of RNA-seq and the visual validation and spatiotemporal resolution of ISH. Integration of this synergistic approach can improve our molecular understanding of non-model organisms and establish the background data needed for advancing research techniques. A prime example lies within an emerging model of the marine science and symbiosis fields, where I present a case study on a threatened coral reef keystone – the cnidarian-dinoflagellate symbiosis. Establishing a whole-mount ISH protocol for the emerging cnidarian model Aiptasia (sea anemone) will help future studies reveal the gene regulation underpinning the establishment, persistence, and breakdown of this complex symbiotic relationship.
