Project description:The English grain aphid, Sitobion avenae, is a major agricultural pest of wheat, barley and oats, and is a major vector of Barley Yellow Dwarf Virus (BYDV) leading to reductions in grain yield. RNA-seq data from a genotype (SA3) was generated from heads and bodies, and from winged and unwinged aphids. The primary goal was to generate evidence for genome annotation, and the secondary goal was to compare expression of genes between head and body, and also between winged and unwinged aphids.
