Project description:Magnaporthe oryzae (rice blast) and the root-knot nematode Meloidogyne graminicola are causing two of the most important pathogenic diseases jeopardizing rice production. Here, we show that root-knot nematode infestation on rice roots leads to important above-ground changes in plant immunity gene expression, which is correlated with significantly enhanced susceptibility to blast disease.

Non-coding RNAs in the interaction between rice and Meloidogyne graminicola

Project description:In this study we generated small RNA libraries from tissues rice plants infected with Meloidogyne graminicola (Mg)3 days postinoculation as well as from uninfected rice plants. The goal was to study the behaviour of small RNA (miRNA and siRNAs) in response to Mg infection. We combine the expression data gathered from this experiment together with degradome sequencing to predict the targets of differentially expressed miRNAs. Expression was validated using RT-qPCR. The small RNA sequencing datasets were also used with literature annotated siRNA loci for differential expression analysis. DNA methylation data and total RNA sequencing data were used to find siRNAs that were candidates to regulate gene expression through DNA methylation of promoter regions.
