Project description:During an incompatible or compatible interaction between rice (Oryza sativa) and the Asian rice gall midge (Orseolia oryzae), a lot of genetic reprogamming occurs in the plant host We used microarray to know the changes occuring in the resistant host (indica rice variety RP2068-18-3-5) when challenged by avirulent biotype of gall midge (GMB 1). During this incompatible interaction the resistance in the host is manifested by a hypersenstive response. Using microarray data, we identified distinct classes of up- and down-regulated genes during this process. Tissues from the stem region (feeding site of insect larvae) of the plants that were exposed to gall midge, were taken for RNA extraction and hybridization on Affymetric microarrays. For control, tissues were taken from the corresponding region of plants that were not exposed to gall midge.

Project description:Yield loss in crop plants due to biotic stresses is a major problem and pyramiding of R genes is often suggested for sustained and durable resistance against target pests. Information is available for single R gene interaction in rice and other crop plants, but not much data is available for multiple R gene interaction against multiple pathogens/pests. In this study we carried out transcriptional analysis of two rice lines introgressed with either R gene against bacterial blight and gall midge or, against bacterial blight and fungal blast. The gene expression changes were investigated through microarray and the expression pattern upon co-infection with multiple pathogens was analyzed to study the synergistic effect of R gene mediated defense responses as well as to explore the possibility of any antagonism between the R genes as defense pathway employed due to R gene mediated resistance variesaccording to the attacking pathogen/pest.

Project description:affy_meloidogyne_rice2 - affy_meloidogyne_rice2 - Plant-parasitic nematodes cause heavy economic losses to global agriculture. The root knot nematode, Meloidogyne incognita, is an obligate parasite that causes significant damage to a broad range of host plants. M. incognita infection to dicotyledous plants is extensively studied but it is also important to study their interaction with monocotyledous plants, in particular with cereals. In our growing conditions, as of day 6, histological studies revealed a profound rice tissue reorganisation around nematodes, notably characterized by the plant feeding site formation. We are investigating the molecular plant response to M. incognita by carrying out a global analysis of gene expression during gall formation in rice, using giant cell-enriched root tissues at this early stage (6dpi) of gall development-Oryza sativa (var. Nipponbare) seedlings were grown on 6 cm3 SAP substrate completed with diluted Hoaglands solution (Reversat et al., 1999). Culture units were placed in a growth chamber illuminated with fluorescent tubes 9/24 h and maintained at 23°C for 6 days before being inoculated with a 300 J2-stage juveniles M. incognita. One day after inoculation (dai), the rice seedlings were immersed in de-ionised water to remove all J2s that had not penetrated the roots and allowing synchronization of the infection. Each seedling was transferred to a hydroponic mini chamber (Reversat et al., 2004). Sampling was performed at 6 dai and each of them contained galls from 45 infected plants, they were then hand-dissected, frozen in liquid-nitrogen and stored at -80°C. As reference samples, uninfected meristematic root fragments were dissected from seedlings grown under the same conditions. Each sample was replicated 3 times. Keywords: normal vs disease comparison

Project description:MicroRNAs (miRNAs) are small noncoding RNAs that play critical roles in regulating post transcriptional gene expression. Gall midges encompass a large group of insects that are of economic importance and also possess fascinating biological traits. The gall midge Mayetiola destructor, commonly known as the Hessian fly, is a model organism for studying gall midge biology and insect – host plant interactions. In this study, we systematically analyzed miRNAs from the Hessian fly. Deep-sequencing a Hessian fly larval transcriptome led to the identification of 89 miRNA species that are either identical or very similar to known miRNAs from other insects, and 184 novel miRNAs that have not been reported from other species. Microarray analyses revealed the expression of miRNA genes was strictly regulated during Hessian fly larval development and abundance of many miRNA genes were affected by host genotypes. The identification of a large number of miRNAs for the first time from a gall midge provides a foundation for further studies of miRNA functions in gall midge biology and behavior.
