Differentially expressed small RNAs in Arabidopsis galls formed by Meloidogyne javanica

ABSTRACT: Root-knot nematodes (RKNs) induce inside the vascular cylinder the giant cells (GCs) imbibed into a gall. Gene-repression in early developing GCs could be facilitated by small RNAs (sRNA) as miRNAs. 24nt-sRNAs, rasiRNAs and 21-22nt-sRNAs can also mediate epigenetic mechanisms. Three sRNA libraries from 3dpi galls and three from uninfected root segments were sequenced following Illumina-Solexa technology. Three sRNA libraries from 3dpi galls and three from uninfected root segments were sequenced

Root-knot nematodes (RKNs) induce inside the vascular cylinder the giant cells (GCs) embedded in the galls. The distinctive gene repression in early-developing GCs could be facilitated by small RNAs (sRNA) such as miRNAs, and/or epigenetic mechanisms mediated by 24nt-sRNAs, rasiRNAs and 21-22nt-sRNAs. Therefore, the sRNA-population together with the role of the miR390/TAS3/ARFs module were studied during early gall/GC formation. Three sRNA libraries from 3-d-post-inoculation (dpi) galls induced  ...[more]
