Antennal Transcriptome of the Fruit-Sucking Moth Eudocima materna: Identification of Olfactory Genes and Preliminary Evidence for RNA-Editing Events in Odorant Receptors.

ABSTRACT: Unappealing shriveled fruits are a characteristic of one of the most elusive fruit pests. The perpetrator, Eudocima materna, attacks the fruit at a fully formed stage and, therefore, the antennal transcriptome for this insect was deduced to identify the molecular elicitors involved in the attraction to its host plants. A total of 260 olfactory genes, including 16 odorant-binding proteins (OBPs), four pheromone-binding proteins (PBPs), 40 antennal-binding proteins (ABPs), 178 odorant receptors (ORs), 17 chemosensory proteins (CSPs) and five sensory neuron membrane proteins (SNMPs) were identified. Phylogenetic analysis shows the divergence of E. materna proteins from closely related lepidopterans and provides insights on genes that have exclusively evolved in this insect. STRI
