The production of RNA molecules was intensified for 165 genes, but decreased for 159 genes. (uni-bayreuth.de)

only a few insects survived, in which E. coli exhibited specific localization to the symbiotic organ and vertical transmission to the offspring. (nature.com)

Interestingly, RNA-seq revealed that G. haimaensis hosts responded to B. pettiboneaei parasitism through significant upregulation of protein and lipid anabolism related genes, and that this parasitism may enhance host mussel nutrient anabolism but inhibit the host's ability to absorb nutrients, thus potentially helping the parasite obtain nutrients from the host.
