Rice perception of symbiotic arbuscular mychorrhizal fungi requires the karrikin receptor complex

Project description:In terrestrial ecosystems plants take up phosphate predominantly via association with arbuscular mycorrhizal fungi (AMF). We discovered that the loss of responsiveness to AMF in the rice deletion mutant hebiba is encoded by the alpha/beta fold hydrolase, DWARF 14 LIKE (D14L), which is one of the 26 deleted genes. It is a component of an intracellular receptor complex involved in the detection of the smoke-compound karrikin. On the basis of the early and pronounced hebiba mutant phenotype, we hypothesized that functional D14L is required for the perception of AM fungi prior to contact. Germinated spore exudates of AMF activate pre-contact plant responses. Therefore, we used RNAseq to monitor the transcriptional changes of hebiba and wild type roots in response to germinated spore exudates, and also karrikin, over the first 24 hours post treatment. WT seedlings were treated with GSE, Karrikin or a mock and iho seedlings with GSE or a mock. Root material was collected for sequencing at 0, 3, 6, 9, 12 and 24 hours. This gave a total of 27 samples (WT+Mock: 6, WT+GSE: 5, WT+Karrikin:5, iho+Mock:6, iho+GSE: 5).

Analysis of gene expression in leaves of Medicago truncatula plants inoculated with arbuscular mycorrhizal fungi and plants fertilized with phosphate

Project description:Arbuscular mycorrhizas (AM) are the most common symbiotic associations between plant’s root compartment and fungi. They can provide both nutritional benefit (mostly inorganic phosphate) leading to improved growth and non-nutritional benefits including defense responses to environmental cues throughout the host plant, which in return delivers carbohydrates to the symbiont. However how transcriptional changes occurring in AM leaves differ from those induced by phosphate fertilization is poorly understood. We investigated systemic changes in the leaves of mycorrhized Medicago truncatula compared to non-mycorrhized control plants, and in phosphate fertilized plants compared to control plants.

Responsivity of two pea genotypes to the symbiosis with rhizobia and arbuscular mycorrhiza fungi – a proteomics aspect of the “Efficiency of Interactions with Beneficial Soil Microoganisms” trait

Project description:It is well-known that individual pea (Pisum sativum L.) cultivars differ in their symbiotic responsivity. This trait is typically manifested with an increase in seed weights due to inoculation with rhizobial bacteria and arbuscular mycorrhizal fungi. The aim of this work was to characterize the alterations in root proteome of highly responsive pea genotype k-8274 and low-responsive genotype k-3358 grown in non-sterile soil, which were associated with root colonization with rhizobial bacteria and arbuscular mycorrhiza fungi in comparison to proteome shifts caused by soil supplementation with mineral nitrogen salts. Our results clearly indicate that supplementation of the soil with mineral nitrogen-containing salts switched the root proteome of both genotypes to assimilation of the available nitrogen, whereas the processes associated with nitrogen fixation were suppressed. Surprisingly, inoculation with rhizobial bacteria had only a minor effect on root proteomes of the both genotypes. The most pronounced response was observed for highly responsive k-8274 genotype inoculated simultaneously with rhizobial bacteria and arbuscular mycorrhizal fungi. This response involved activation of the proteins related to redox metabolism and suppression of excessive nodule formation. In turn, the low-responsive genotype k-3358 demonstrated a pronounced inoculation-induced suppression of protein metabolism and enhanced diverse defense reactions in pea roots under the same soil conditions. The results of the study shed light on the molecular basis of differential symbiotic responsivity in different pea cultivars.

Gene profiling in arbuscular mycorrhizal symbiosis between the actinorhizal tree Casuarina glauca and the fungus Glomus intraradices.

Project description:Casuarina glauca belongs to a family of angiosperms called actinorhizal plants because they can develop nitrogen-fixing nodules in association with the soil bacteria Frankia. They can also develop arbuscular mycorrhizae (AM) while associated with Glomeromycota fungi. The aim of this transcriptomic study was to get a global view of the plant symbiotic genetic program in AM and to identify new key plant genes involved in endosymbioses.
