Project description:Magnaporthe oryzae is the causative agent of the rice blast, the most relevant rice disease worldwide. To date expression analysis on rice infected with Magnaporthe oryzae have been carried out only with the strains FR13 (leaf) and Guy 11 (root). However different strains of Magnaporthe are present in the environment leading to different rice responses at molecular level. To gain more insight on the unknown molecular mechanisms activated by different Magnaporthe strains during rice defense, a global expression analysis was performed by using the GeneChip® Rice Genome Array. To identify rice genes differentially regulated upon infection by Magnaporthe isolates, inoculation with different strains were performed and samples were collected 24 hours post infection.
Project description:In this experiment the transcriptome reprogramming in wheat during host and nonhost interaction with Magnaporthe sp. was analyzed in a time-series approach. Seven days old wheat plants of cv. Renan were mock-inoculated or inoculated with adapted Magnaporthe isolate Br116.5 from wheat or non-adapted isolate CD180 from Pennisetum. After 6, 12, 24 and 48 hours the abaxial epidermis was sampled. Total RNA was extracted using the RNeasy Plant Mini Kit with on-column DNase digestion (Qiagen, Hilden, Germany), and hybridized to Agilent 44k oligonucleotide arrays.
Project description:In this experiment the transcriptome reprogramming in barley during host and nonhost interaction with Magnaporthe sp. was analyzed in a time-series approach. Seven days old barley plants of cv. Vada were mock-inoculated or inoculated with adapted Magnaporthe isolate TH6772 from rice or non-adapted isolate CD180 from Pennisetum. After 6, 12, 24 and 48 hours the abaxial epidermis was sampled. Total RNA was extracted using the RNeasy Plant Mini Kit with on-column DNase digestion (Qiagen, Hilden, Germany), and hybridized to Agilent 44k oligonucleotide arrays.
