Small scale genetic screen identifies astrocytic cues that drive Beat-Va _M remodeling. (A) Pie chart summarizing the results of the screen, indicating the number of lines per phenotypic category. Astrocyte knockdown of candidate molecules was achieved by UAS-driven RNAi’s, and Beat-Va neurons were visualized with Beat-LexA–driven CD4-tdGFP. (B–V) Show Beat-VaM neurons, grouped by phenotype and color-coded to match the pie chart in A, with the gene which the RNAi targeted indicated above the corresponding image. Scale bar is 20 µm. Five animals were examined per condition, and phenotypes shown are representative of what was observed.
