Molecular mechanisms of selfish elements and strategies
Certain genes, chromosomes, organelles, or entire sets of chromosomes can bias their transmission to the next generation, propagating themselves at the expense of the rest of the genome. Referred to …

Infection dynamics of endosymbionts that manipulate arthropod reproduction
A large proportion of arthropod species are infected with endosymbionts, some of which selfishly alter host reproduction. The currently known forms of parasitic reproductive manipulations are male-ki...

Wolbachia bacteria hijack insect reproduction by killing off males, but it turns out they don’t use the same weapon in every species. New research uncovers species-specific genes with a license to kill.
A license to kill
Bacteria belonging to the Wolbachia family employ distinct genes to kill the male offspring of different insect species.

Our final version of eLife paper (VOR) is now out! (doi.org/10.7554/eLif...). I investigated functions of wmk and Oscar homologs in a native host (moth) with @daisukekageyama.bsky.social and others:))
Prophage-encoded Hm-oscar gene recapitulates Wolbachia-induced male-killing in the tea tortrix moth Homona magnanima
Oscar homologs play a conserved role in Wolbachia-induced male-killing in Lepidoptera but not in other insects, highlighting the evolution of diverse male-killing mechanisms induced by Wolbachia.

Very happy to start the new year with publication of our new work on leaf surface RNA. Plant leaves secrete diverse RNAs that are surprisingly stable on their surfaces. Next question to answer: What do they do? www.pnas.org/doi/epub/10....
