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 show which repeat-associated small interfering RNAs (rasiRNAs) are distinctive or enriched in early Arabidopsis galls vs. uninfected roots. Those distinctive from galls are preferentially located in pericentromeric regions with predominant sizes of 24 and 22 nucleotides. Gall-distinctive rasiRNAs target primarily GYPSY and COPIA retrotransposons, which show a marked repression in galls vs. uninfected roots. Infection tests and phenotypic stud...Continue Reading
