Author Correction: Transcriptome analysis of the salivary glands of the grain aphid, Sitobion avenae (Scientific Reports, (2017), 7, 1, (15911), 10.1038/s41598-017-16092-z)

Aphid saliva plays important roles in aphid-host interactions, such as assisting aphid digestion,
detoxification, activating or suppressing plant defenses. The grain aphid, Sitobion avenae, is one of the
most devastating pests of cereals worldwide. In this study, we performed the transcriptome analysis of
salivary glands of S. avenae. A total of 33,079 assembled unigenes were identified in the salivary glands
of aphids. Of the all obtained unigenes, 15,833(47.86%) and 10,829(32.73%) unigenes showed high
similarity to known proteins in Nr and Swiss-Prot databases respectively. 526 unigenes were predicted
to encode secretory proteins, including some digestive and detoxifying enzymes and potential
effectors. The RT-PCR and RT-qPCR results showed that all of the 15 most highly expressed putative
secretory proteins specifically expressed in salivary glands. Interestingly, 11 of the 15 most highly
expressed putative secretory proteins were still not matched to function-known proteins. We also
detected the expression of 9 interested putative secretory proteins in aphid different tissues, including
some digestive and detoxifying enzymes, effectors and Ca2+ binding proteins. The results showed that
only glutathione-S-transferase 1 was specifically expressed in salivary glands. These findings provide a
further insight into the identification of potential effectors involving in aphid-cereals interactions. amendment to this paper has been published and can be accessed via a link at the top of the paper. © 2020, The Author(s).
