Project description:An indica rice cultivar FR13A, is widely grown as submergence tolerant variety and can withstand submergence up to two weeks. The tolerance is governed by a major QTL on chromosome 9 and represented as sub1. Recently the gene for sub1 has been mapped and cloned. However, the trait is governed by several QTLs and not by a single gene. To understand the mechanism of submergence tolerance we selected, two indica rice genotypes namely, I) FR13A, a tolerant indica variety and ii) IR24, a susceptible genotype for this study. We used the 22K rice Oligoarray from Agilent technologies to study the transcript profile in the leaves of the two contrasting rice genotypes under constitutive and submerged conditions at seedling stage. Keywords: Mechanism of submergence tolerance

Project description:A submergence tolerant indica rice cultivar FR13A, was also reported to withstand salt stress and proven in our experiments. The mechanism of tolerance is yet to be studied by forward genetics approach. However, it is known that salt stress tolerance is governed by several QTLs and not by a single gene. To understand the mechanism of such a complex mechanism of salt tolerance we selected, two indica rice genotypes namely, I) FR13A, a tolerant indica variety and ii) IR24, a susceptible genotype for this study. We used the 22K rice Oligoarray from Agilent technologies to study the transcript profile in the leaves of the two contrasting rice genotypes under constitutive and salt stress conditions at seedling stage.

Project description:An indica rice cultivar IET8585 (Ajaya), resists diverse races of the Xanthomonas oryzae pv oryzae (Xoo) pathogen attack, and is often cultivated as bacterial leaf blight (blb) resistant check in India. Earlier we reported a recessive blb resistance gene mapped to the long arm of chromosome 5 in IET8585. To further understand the mechanism of recessive and durable resistance response, two indica rice genotypes namely, i) IET8585 (Ajaya), a disease resistant indica veriety from India and ii) IR24, a bacterial leaf blight disease susceptible genotype were selected for this study. We used the 22K rice Oligoarray from Agilent technologies to study the transcript profile in the leaves of the two contrasting rice genotypes under inoculated and un-inoculated conditions during seedling stage.

Project description:Plant response to insect feeding appears to be highly specific with regard to the organisms in the system. Here, we report on the interaction between grapevine Vitis vinifera plants and a phloem-feeding insect pest, the vine mealybug Planococcus ficus. Plants were exposed to P. ficus for periods of 6 hours and 96 hours, after which they were analysed for gene expression levels using microarrays and quantitative real-time PCR (qPCR). Both methods showed that grapevine displayed only a minimal response to mealybug feeding at the transcript level at both time periods. Intermediate grapevine exposure times (24, 48 and 72 hours) to P. ficus feeding were investigated using qPCR analysis of ten additional genes associated with known plant defense responses. Results showed that only a single gene, pathogenesis-related protein 1, was differentially expressed after 48 hours of mealybug feeding. During the course of mealybug feeding, however, a number of other genes were significantly up- or down-regulated at certain time points. Thus, it appears as if grapevine responds minimally to feeding by P. ficus as well as within a very narrow time period. The relative lack of grapevine plant defense mechanisms may be a result of the feeding strategies of mealybugs.
