Project description:Rice roots grown in hydroponic culture were inoculated with rice blast fungus and gene expression profiles were analyzed by microarray Roots of two isogenic lines of rice cv Nipponbare (blast-resistance gene: Pia or pia) were inoculated with rice blast fungus, P91-15B, carrying avirulence gene, AvrPia. Total RNA was isolated from crown roots, labeled with cy3, and probed with agilent rice oligoarray (4x44).

Project description:Magnaporthe oryzae causes rice blast, the most devastating foliar fungal disease of cultivated rice. During disease development the fungus simultaneously maintains both biotrophic and necrotrophic growth corresponding to a hemi-biotrophic life style. The ability of M. oryzae to also colonize roots and subsequently develop blast symptoms on aerial tissue has been recognized. The fungal root infection strategy and the respective host responses are currently unknown. Global temporal expression analysis suggested a purely biotrophic infection process reflected by the rapid induction of defense response-associated genes at the early stage of root invasion and subsequent repression coinciding with the onset of intracellular fungal growth. The same group of down-regulated defense genes was increasingly induced upon leaf infection by M. oryzae where symptom development occurs shortly post tissue penetration. Our molecular analysis therefore demonstrates the existence of fundamentally different tissue-specific fungal infection strategies and provides the basis for enhancing our understanding of the pathogen life style. Experiment Overall Design: We investigated global transcriptome response overtime of Mock- and M. oryzae inoculated rice root tissue in vitro. Two independant replicates were perfomed for each treatments and samples were collected at 2, 4 and 6 days post-inoculation.

Project description:Purpose: Transcriptional profiling of Oryza sativa japonica Nipponbare roots after one, three and seven days post inoculation with Azoarcus olearius BH72 (vs. non-inoculated controls) to understand the changes in transcriptomic response of rice roots to colonization by bacterial endophyte at initial stages of interaction; Additional set-up was included in which bacterial growth was boosted (through increasing 20-times carbon source - malic acid in the plant's hydroponic medium) to study rice roots transcriptome during enhanced colonization by the endophyte after three days post inoculation. Methods: Rice root mRNA profiles after one day, three days (including additional set-ups for boosted colonization), and seven days post inoculation with Azoarcus olearius BH72 and corresponding non-inoculated controls were generated by RNA sequencing, in triplicates, using Illumina NextSeq 500. Raw reads were then filtered, trimmed (PHRED > 33) and mapped onto IRGSP-1 version of Oryza sativa ssp. japonica cv. Nipponbare genome using CLC Genomics Workbench 8.5.1 (Qiagen, Germany). Expression of 17 selected genes was confirmed via RT-qPCR. Results: Using the RNA-Seq technology we obtained transcriptomic data from 24 sequencing libraries, with an average 46,181,160 clean reads per library, of which 87% or more were mapped onto the Oryza sativa ssp. japonica cv. Nipponbare IRGSP-1.0 genome (Fig. S3). We considered genes as differentially regulated (DEG) that exhibited at least 1.5-fold-change in expression level between Azo-colonized and non-colonized roots and FDR<0.05. Conclusions: Bacteria appeared to short-circuit the initial root defense responses for a compatible interaction during endophytic establishment, involving previously unknown putative rice candidate genes.

Project description:Rings or arcs of fungus-stimulated plant growth occur often on the floor of woodlands which are commonly called “fairy rings”. We purified a plant growth-stimulating compound, 2-azahypoxanthine (AHX), from the fairy ring-forming fungus Lepista sordida, and the detection of AHX in the fungus-infected soil near the growth-stimulated turfgrass roots. The growth-promoting activity of AHX towards rice was further analyzed by oligo DNA microarrays.
