Comparative transcriptomic analyses revealed divergences of two agriculturally important aphid species
Grain aphid and pea aphid are two agriculturally important pest species, which cause significant yield losses to crop plants
Abstract
Grain aphid and pea aphid are two agriculturally important pest species, which cause significant yield losses to crop plants each year by inflicting damage both through the direct effects of feeding and by vectoring debilitating plant viruses. Although a close phylogenetic relationship between grain aphid and pea aphid was proposed, the biological variations between these two aphid species are obvious. While the host ranges of grain aphid is restricted to cereal crops and in particular wheat, that of pea aphid is wider, mainly colonizing leguminous plant species. Until now, the genetic factors underlying the divergence between grain aphid and pea aphid still remain unclear due to the limited genomic data of grain aphid available in public databases.
This work arises from the Sustainable Crop production for International Development (SCPRID) programme.
