Note. —Table cells are highlighted in light or intense green depending on the presence of a functional gene or a detected pseudogene. Functions are those determined for homologous baculovirus proteins. Core genes of nudiviral origin conserved in braconid wasps associated with bracoviruses and VcENV are listed for comparison. The different values indicated in transcript abundance column correspond to the expression of the different gene copies.
Pseudogene identified in addition to the functional core gene.
Gene family.
−, no pseudogene detected; nd, not determined; s.u., subunit.
