Project description:Expression data from rice lesion mimic mutant spotted leaf 5 (spl5)
| PRJNA262775 | ENA
Project description:Lesion mimic mutants in rice are widely known as spotted leaf (spl) mutants, of which several genotypes exhibit enhanced resistance to different races of Magnaporthe grisea. Besides naturally occurring spotted leaf mutants, tissue culture-induced reverse genetic repositories also act as sources of lesion mimic mutants in rice. We systematically evaluated a large collection of Tos17 mutant panel lines, developed and maintained at the National Institute of Agrobiological Sciences, Tsukuba, Japan, for their reaction to three different races of M. grisea and identified a lesion mimic mutant, NF4050-8, that showed lesions similar to naturally occurring spl5 mutant and enhanced resistance to all three blast races tested. Microarray analysis of ~44,000 rice genes in NF4050-8 with Nipponbare as control during the progressive lesion appearance stage revealed significant up-regulation of numerous defense/pathogenesis-related genes as well as several WRKY domain-containing genes and down-regulation of haem peroxidase gene. Subsequent real-time PCR analysis of WRKY45 and PR1b genes in NF4050-8 and spl5 suggested possible constitutive activation of a defense signaling pathway downstream of Salicylic Acid (SA) but independent of NH1 in these mutant lines of rice.

We used Agilent rice oligo microarrays to identify putative defense/pathogenesis-related genes. Leaf tissues of the rice genotypes Nipponbare and NF4050-8 were used in the study. Two replications of microarray experiments were carried out by hybridizing the cRNA from control and progressive lesion appearance stage on 4 x 44k microarray.

Project description:The rice lesion mimic, spotted leaf 5 (spl5), created by M-NM-3-ray radiation, has spontaneous HR-like lesions on its leaves and shows enhanced resistance to rice blast and bacterial blight pathogens. Some genes were differentially expressed in this mutant compared with its WT control ZF802, and these genes were also associated with some important signaling pathways, such as defense response, oxidation-reduction process and stress response. We analyzed the transcriptional profiling of spl5 mutant and WT using the microarray, in order to reveal the signal pathway of SPL5 gene in regulation of disease resistance. Rice leaves were selected at lesion stages of spl5 mutant for RNA extraction and hybridization on Affymetrix microarrays. The lesions in rice leaves were belong to HR phenotype, which was one of the important reasons for rice disease resistance. In order to realize which genes were associated with the degree of lesions and mediated the disease resistance, we put the leaves of spl5 mutant into two categories, based on the degree of lesion formation: few lesions (FL), leaf area with 10-20% lesions and many lesions (ML), leaf area with 70-80% lesions.

Project description:The first GSSM of V. vinifera was reconstructed (MODEL2408120001). Tissue-specific models for stem, leaf, and berry of the Cabernet Sauvignon cultivar were generated from the original model, through the integration of RNA-Seq data. These models have been merged into diel multi-tissue models to study the interactions between tissues at light and dark phases.

Project description:Secondary metabolites are involved in the plant stress response. Among these are scopolin and its active form scopoletin, which are coumarin derivatives associated with reactive oxygen species scavenging and pathogen defence. Here we show that in Arabidopsis thaliana, scopolin accumulation can be induced in the root by osmotic stress and in the leaf by low temperature stress. A genetic screen for altered scopolin levels in Arabidopsis thaliana identified a mutant compromised for scopolin accumulation in response to stress; the lesion was present in a homologue of THO1, the product of which contributes to the THO/TREX complex. The THO/TREX complex contributes to RNA silencing, supposedly by trafficking precursors of small RNAs. Mutants carrying defective THO and RDR6 genes were impaired with respect to scopolin accumulation in response to stress, suggesting a mechanism based on RNA silencing like the transacting small interfering RNA pathway which requires THO/TREX and RDR6 function.
