    • Proteo-trancriptomic analyses reveal a large expansion of metalloprotease-like proteins in atypical venom vesicles of the wasp Meteorus pulchricornis (Braconidae) 

      Gatti, J.L.; Belghazi, M.; Legeai, F.; Ravallec, M.; Frayssinet, M.; Robin, S.; Aboubakar-Souna, D.; Srinivasan, R.; Tamὸ, M.; Poirie, M.; Volkoff, A.N. (2021-07-19)
      Meteorus pulchricornis (Ichneumonoidea, Braconidae) is an endoparasitoid wasp of lepidopteran caterpillars. Its parasitic success relies on vesicles (named M. pulchricornis Virus-Like Particles or MpVLPs) that are synthesized in the venom gland and injected into the parasitoid host along with the venom during oviposition. In order to define the content and understand the biogenesis of these atypical vesicles, we performed a transcriptome analysis of the venom gland and a proteomic analysis of the ...
