Tripartite symbiosis formed by Pisum sativum, rhizobia and mycorrhiza: Implications for the symbionts, the host plant and the pathogenic fungi, part 1

ABSTRACT: The lower needs for chemical fertilisers make the Pisum Sativum well suited for sustainable agricultural systems. During the past decades, yield losses were mainly due to pathogenic infestation, with Ascochyta blight as the most severe disease. In this fungal disease complex Didymella pinodes, as the most aggressive pathogen, has been examined intensively. Despite the great number of varieties, no resistance was yet found and several strategies were developed to avoid infestation. In recent years enhanced resistance to pathogens due to previous infestation by symbiotic microorganisms was discovered in several plants. However, only little attention was drawn on the implications of P. Sativum´s symbionts (Rhizobia, Mycorrhiza) on the disease severity as well as the effects of the pathogen on the symbiotic interactions. Hence, here the implications of the pathogenic infestation on the tripartite symbiosis of P. Sativum on a molecular (proteomics, metabolomics) and physiological level, and moreover, the potential of the root symbionts to enhance resistance against Didymella pinodes are investigated.

<h4>Unlabelled</h4>The long cultivation of field pea led to an enormous diversity which, however, seems to hold just little resistance against the ascochyta blight disease complex. The potential of below ground microbial symbiosis to prime the immune system of Pisum for an upcoming pathogen attack has hitherto received little attention. This study investigates the effect of beneficial microbes on the leaf proteome and metabolome as well as phenotype characteristics of plants in various symbiont ...[more]

Project description:Cultivated rice (Oryza sativa L.) is frequently exposed to multiple stresses, including Schizotetranychus oryzae mite infestation. Rice domestication has narrowed the genetic diversity of the species, leading to a wide susceptibility. This work aimed to observe the response of two wild rice species (Oryza barthii and O. glaberrima) and two O. sativa genotypes (cv. Nipponbare and f. spontanea) to S. oryzae infestation. Surprisingly, leaf damage, histochemistry, chlorophyll concentration and fluorescence showed that the wild species present higher level of leaf damage, increased accumulation of H2O2 and lower photosynthetic capacity when compared to O. sativa genotypes under infested conditions. Infestation decreased tiller number, except in Nipponbare. Infestation also caused the death of wild plants during the reproductive stage. While infestation did not affect the weight of 1,000 grains in both O. sativa genotypes, the number of panicles per plant was affected only in f. spontanea, and the percentage of full seeds per panicle and seed length were increased only in Nipponbare. Using proteomic analysis, we identified 195 differentially abundant proteins when comparing susceptible (O. barthii) and tolerant (Nipponbare) genotypes under control and infested conditions. O. barthii has a less abundant antioxidant arsenal and is unable to modulate proteins involved with general metabolism and energy production under infested condition. Nipponbare presents high abundance of detoxification-related proteins, general metabolic processes and energy production, suggesting that, under infested condition, the primary metabolism is maintained more active compared to O. barthii. Also, under infested conditions, Nipponbare presents higher levels of proline and a greater abundance of defense-related proteins, such as osmotin, ricin B-like lectin, and protease inhibitors. These differentially abundant proteins can be used as biotechnological tools in breeding programs aiming increased tolerance to mite infestation.

Project description:Soybean is one of the most important sources of food, protein, and oil in the world. Reductions in grain number and quality are caused by different biotic stresses. One of the most common is the phytophagous mite Tetranychus urticae Koch (Acari: Tetranychidae), which inhibits plant growth and grain production. The identification of plant responses to early and late T. urticae infestation is important for a better understanding of the mite-plant interaction. We therefore aimed to evaluate the physiological and molecular responses of soybean plants to mite infestation for 5 and 21 days. Visual and microscopic symptoms of leaf damage, H2O2 accumulation, and lipid peroxidation increased consistently throughout the infestation period, while shoot length/dry weight, chlorophyll level, and number of days to reach specific developmental stages were negatively affected by T. urticae infestation. Using proteomic analysis, we identified 185 and 266 differentially abundant proteins after early (5 days) and late (21 days) mite infestation, respectively, which suggests a complex remodeling of diverse metabolic pathways. GO, KEGG, and protein-protein interaction analyses indicated that photorespiration, chlorophyll synthesis, amino acid metabolism, Krebs cycle/energy production, mitochondrial translation, nucleotide salvage, PS II assembly, and reductive pentose-P cycle are all impacted after both early and late infestation. Specific metabolic pathways modified only after early infestation include cell wall modification, cytoskeleton composition, cell division, and lysine/histidine metabolism, while JA biosynthesis, antioxidant system, S-adenosyl methionine cycle, PS II repair, cysteine/methionine/glutathione/ascorbate/-linolenic acid/selenocompound metabolism, arginine biosynthesis, and proteasome are modified only after late infestation. These differentially abundant proteins can be used as biotechnological tools in future breeding programs aiming at increased resistance to mite infestation.
