Silenced retrotransposons are major rasiRNAs targets in Arabidopsis galls induced by Meloidogyne javanica.

ABSTRACT: Root-knot nematodes (RKNs, Meloidogyne spp.) are sedentary biotrophic pathogens that establish within the vascular cylinder of plant roots, forming a gall and inducing several feeding cells, giant cells (GCs), essential for completion of their life cycle. GCs suffer gene expression changes, repeated mitosis and endoreduplication events. Transcriptomics has revealed that an extensive down-regulation of transcripts, a molecular signature of early-developing galls and GCs that is conserved in tomato and Arabidopsis, may be achieved through small RNA (sRNA) gene silencing pathways. The role of some microRNAs (miRNAs) in plant-RKN interactions has recently been addressed, but little is known about the regulatory roles of other sRNA types. Here, we perform a differential accumulation analysis to
