The genome of the soybean gall midge (Resseliella maxima).

The cecidomyiid fly, soybean gall midge, Resseliella maxima Gagné, is a recently discovered insect that feeds on soybean plants in the Midwestern United States. R. maxima larvae feed on soybean stems that may induce plant death and can cause considerable yield losses, making it an important agricultural pest.

The Genome of the Soybean Gall Midge ( ).

The cecidomyiid fly, soybean gall midge, Gagné, is a recently discovered insect that feeds on soybean plants in the Midwest US. larvae feed on soybean stems which may induce plant death and can cause considerable yield losses, making it an important agricultural pest. From three pools of 50 adults each, we used long-read nanopore sequencing to assemble a reference genome.

The intracellular symbiont alters development and metabolism to buffer against nutritional stress.

Unlabelled: The intracellular bacterium is a common symbiont of many arthropods and nematodes, well studied for its impacts on host reproductive biology. However, its broad success as a vertically transmitted infection cannot be attributed to manipulations of host reproduction alone. Using the model and their natively associated strain " Mel", we show that infection supports fly development and buffers against nutritional stress.

Infection Dynamics of Cotransmitted Reproductive Symbionts Are Mediated by Sex, Tissue, and Development.

One of the most prevalent intracellular infections on earth is with , a bacterium in the that infects a range of insects, crustaceans, chelicerates, and nematodes. is maternally transmitted to offspring and has profound effects on the reproduction and physiology of its hosts, which can result in reproductive isolation, altered vectorial capacity, mitochondrial sweeps, and even host speciation. Some populations stably harbor multiple strains, which can further contribute to reproductive isolation and altered host physiology.
