Comparative transcriptome analysis of chemosensory genes in the male and female adults of Maruca vitrata
In moths, mating behavior is induced by sex pheromones released by the female being recognized by the males’s chemosensory systems. In this study, to understand the recognition of sex pheromones in Maruca vitrata, chemosensory genes were identified via transcriptome analysis of male and female antennae and heads. Approximately, 11.1Gb, 10.8Gb, 12.1Gb, and 11.6Gb of data were obtained from the antennae and heads of the male and female, respectively. Thirty-seven odorant binding proteins (OBPs), 21 chemosensory proteins, 7 sensory neuron membrane proteins, 102 odorant receptors (ORs), 36 ionotropic receptors, and 39 gustatory Receptors were identified as chemosensory genes from the M. vitrata. Among these genes, 5 OBPs and 4 ORs were specifically expressed in male antennae. These genes are likely to be involved in the sex pheromone recognition of M. vitrata.
