Expression of small RNA in Aphis gossypii and its potential role in the resistance interaction with melon.

ABSTRACT:

Background

The regulatory role of small RNAs (sRNAs) in various biological processes is an active area of investigation; however, there has been limited information available on the role of sRNAs in plant-insect interactions. This study was designed to identify sRNAs in cotton-melon aphid (Aphis gossypii) during the Vat-mediated resistance interaction with melon (Cucumis melo).

Methodology/principal findings

The role of miRNAs was investigated in response to aphid herbivory, during both resistant and susceptible interactions. sRNA libraries made from A. gossypii tissues feeding on Vat⁺ and Vat⁻ plants revealed an unexpected abundance of 27 nt long sRNA sequences in the aphids feeding on Vat⁺ plants. Eighty-one conserved microRNAs (miRNAs), twelve aphid-specific miRNAs, and n
