Finally, Hunter Hill used In(1)w^m4 (one of the original X-chroms from Muller's 1930 paper) to show Wolbachia acts as a variegation suppressor. Wolbachia-mediated modification of paternal chromatin during spermatogenesis leaves a persistent signature on heterochromatin-mediated silencing. Very cool

assesses temperature modulation of cytoplasmic incompatibility strength across 8 systems. With the help of Lore, Tim (Phd), and Elena/Kyle (undergrads), we show cifB expression partly explains temp-sensitive CI, while bacterial density in testes does not.
Excited to share this preprint!! with

We tested whether endosymbiotic Wolbachia can alter host gene expression through chromatin modifications that persist from spermatogenesis to adulthood.
