Project description:Plant-plant interactions modulate foliar disease susceptibility in intraspecific mixtures. However, the molecular events including signals and responses underlying the reduction in disease susceptibility remain largely unexplored.
Here, we developed an experimental system that can abolish root-mediated interactions between plants in a model of bread wheat varietal mixture. We then performed transcriptomic and metabolomic analyses to uncover the molecular responses linked to decreased susceptibility to Septoria tritici blotch in plant-plant interactions.
Our analysis revealed that disrupting root chemical interactions impaired the reduction in susceptibility to Septoria and identified phenolic compounds as potential key mediators. The plant-plant interactions under study triggered significant molecular changes in specialized metabolism, biotic interactions, transporters, and responses to resources. Disrupting root interactions canceled both the macroscopic and molecular responses, thus providing a strong link between them.
These insights provide a deeper understanding of the molecular basis of plant-plant interactions and the processes involved in reducing disease susceptibility in intraspecific mixtures.

Project description:Considering global climate changes, incidences of combined drought and heat stress are likely to increase in the future and will considerably influence plant-pathogen interactions. Until now, little is known about plants exposed to simultaneously occurring abiotic and biotic stresses. To shed some light on molecular plant responses to multiple stress factors, a versatile multi-factorial test system, allowing simultaneous application of heat, drought and virus stress, was developed. Comparative analysis of single, double and triple stress responses by transcriptome and metabolome analysis revealed that gene expression under multi-factorial stress is not predictable from single stress treatments. Hierarchical cluster and principal component analysis identified heat as the major stress factor clearly separating heat-stressed from non-heat stressed plants. We identified 11 genes differentially regulated in all stress combinations as well as 23 genes specifically-regulated under triple stress. Furthermore, we showed that virus treated plants displayed enhanced expression of defense genes, which was abolished in plants additionally subjected to heat and drought stress. Triple stress also reduced expression of genes involved in the R-mediated disease response and increased the cytoplasmic protein response which was not seen under single stress conditions. These observations suggested that abiotic stress factors significantly altered TuMV-specific signaling networks which lead to a deactivation of defense responses and a higher susceptibility of plants. Collectively, our transcriptome and metabolome data provide a powerful resource to study plant responses during multi-factorial stress and allows identifying metabolic processes and functional networks involved in tripartite interactions of plants with their environment. Stress induced gene expression in Arabidopsis leaves was measured after exposure to single and combined abiotic and biotic stress. Plants were grown on soil for 21 days till virus infection. Eight days later controlled drought stress was applied. At the end of the treatments heat was applied for three days. Four biological replicates have been hybridized for each treatment. Furthermore, Arabidopsis plants were exposed to a single severe heat stress (37°C day/33°C night) to mimic the severity of the triple stress experiment.

Project description:Sesamum indicum is an oilseed crop. One of the biotic factor that affect the production is a phyllody disease caused by phytoplasma which may target the reproductive system of the plant rendering the plant sterile. The aim of the study is to see the differential expression at proteomic level during the phytoplasma infection in Sesamum indicum.

Project description:Background: Plant disease is a major challenge to agriculture worldwide, and it is often exacerbated by abiotic environmental factors. During some plant-pathogen interactions, heat stress increases host susceptibility, a tendency which could spell disaster in light of the global warming trends associated with climate change. Despite the importance of this phenomenon, little is known about the molecular mechanisms that cause it. To better understand host plant responses during simultaneous heat and pathogen stress, we conducted a transcriptomics experiment for rice plants infected with Xanthomonas oryzae (Xo), an economically important bacterial pathogen of rice, during high temperature stress. Results: Using RNA-Seq technology, 8,499 differentially expressed genes were identified as temperature responsive in one rice cultivar, IRBB61, experiencing susceptible and resistant interactions with Xo across three time points. Many genes with gene ontology terms associated with stress response were identified. Notably, genes in the plant hormone abscisic acid (ABA) biosynthesis and response pathways were identified as upregulated by high temperature in both mock-treated plants and plants in the susceptible interaction and suppressed by high temperature in plants in the resistant interaction. A DNA sequence motif similar to known ABA-responsive cis-regulatory elements was identified in the promoter region upstream of genes upregulated in susceptible but downregulated in resistant interactions. Conclusions: The results of our study suggest that the plant hormone ABA is an important node for cross-talk between plant transcriptional response pathways to high temperature stress and pathogen attack. Genes in this pathway represent an important focus for future study to determine how plants evolved to deal with simultaneous abiotic and biotic stresses.

Project description:Rapid responses to biotic and abiotic insults are crucial for plant survival. We examined the very early (10 min) wound transcriptome in order to increase our understanding regarding this critical intial phase of the plant response to stress. Our analysis revealed a rapid induction of stress-related transcripts that was distinct from the long term events which are dominated by jasmonic pathway responses. The transcriptome showed high correlation between the early wound response and other early but not late responses to innate immune interactions and other abiotic stresses. In addition those early responses were correlated with transcriptomes of response to singlet oxygen as displayed in the flu mutant. Singlet oxygen appears to be a signaling intermediate in the plant response to multiple stresses.
