Project description:Pteris cretica L var. nervosa is one of the dominent fern species at antimony mining area where arbuscular mycorrhizal fungi can be found as a symbiosis. The effect of AMF on fern exposed to long-term excessive Sb was pooly understood. The project applied this fern co-cultivting with or withour AMF under different concentration of Sb in soil for charicterising Sb phytomediation ability of it along with the effect by AMF symbiosis.

Project description:Although previous studies have addressed the possible benefits of arbuscular mycorrhizal (AM) symbiosis for rice plants under salinity, the underlying molecular mechanisms are still unclear. Here, we showed that rice colonized with AM fungi had better growth performance and higher K+/Na+ ratio under salt stress. Differentially expressed genes (DEGs) responding to AM symbiosis especially under salt stress were obtained from RNA sequencing. AM-regulated DEGs in cell wall modification and peroxidases categories were mainly upregulated in shoots, suggesting AM symbiosis might assist in relaxing the cell wall and scavenging reactive oxygen species (ROS). AM symbiosis indeed improved ROS scavenging capacity in rice shoots under salt stress. In addition, genes involved in Calvin cycle and terpenoid synthesis were enhanced by AM symbiosis in shoots and roots under salt stress, respectively. AM-upregulated cation transporters and aquaporin in both shoots and roots were highlighted. Strikingly, “protein tyrosine kinase activity” subcategory was the most significantly over-represented GO term among all AM-upregulated and downregulated DEGs in both shoots and roots, highlighting the importance of kinase on AM-enhanced salinity tolerance. Overall, our results from the transcriptomic analyses indicate that AM symbiosis uses a multipronged approach to help plants achieve salt stress tolerance.

Project description:The influence of arbuscular mycorrhizal (AM) colonization on the expression of genes in the roots of wheat (Triticum aestivum L.) at the transcriptome level is largely unknown. A pot experiment was established to study the responses of the transcriptome profile in the roots of wheat to colonization by the AM fungus Rhizophagus irregularis using high through-put sequencing methods. The results indicated that the expression of 11,746 genes was regulated by AM colonization, and 64.7% of them were up-regulated genes. 1106 genes were only expressed in roots colonized by AMfungi, and 108 genes were only expressed in non- mycorrhizal roots. The differentially expressed genes (DEGs) were primarily distributed on the 2B, 3B, 2A, 2D, and 5B chromosomes of wheat. The DEGs (including both up- and down- regulated) mainly located on membranes, and functioned in nucleotide binding and transferase activity during cellular protein modification and biosynthetic processes. The data revealed that AMcolonization up-regulated genes involved in the phenylpropanoid biosynthesis pathway and transcription factors which play vital roles in protecting plants from biotic or abiotic stresses. A number of key genes involved in molecular signal biosynthesis and recognition, epidermal cell colonization and arbuscule formation, carbon and nutrients exchange during AM symbiosis were found. All the ammonium transporter (AMT), iron-phytosiderophore transporter, boron, zinc, and magnesium transporter genes found in our study were up-regulated DEGs. One new AM-specific induced AMT and three new AM-specific induced nitrate transporter (NRT) genes were found in the roots of wheat colonized by AMfungi, even though a negative growth response of wheat to AM colonization occurred. The present study provided new information which is important for under- standing the mechanisms behind the development and function of the symbiosis between wheat and AM fungi.

Project description:MicroRNAs (miRNAs) are small non-coding RNAs that regulate target mRNAs by inducing degradation or preventing translation of their target mRNAs. Winter wheat, Triticum aestivum., is an important crop plant, yet there are only a few studies on the association of miRNAs and growth and development of winter wheat grown in the field. Here we carried out experimental analysis of miRNAs in wheat leaves by analyzing small RNA profiles at different growth stages.

Project description:Most vascular flowering plants have the ability to form mutualistic associations with soil fungi from the Glomeromycota. The resulting symbiosis is called an arbuscular mycorrhiza and they are widespread in terrestrial ecosystems throughout the world. Although the physical interaction between the symbionts occurs in the root cortex, the symbiosis impacts the physiology of the whole plant. To gain a better understanding of the AM symbiosis, we have used the 16000 feature array to examine gene expression in the leaves of mycorrhizal plants to explore the transcriptional changes that are triggered systemically as a result of the AM symbiosis.

Project description:MicroRNAs (miRNAs) are single strand small non-coding RNAs that regulate target mRNAs at post-transcription level. Winter wheat (Triticum aestivum L.), is an important crop plant all over the world. Long term cold exposure (vernalization) is necessary for winter wheat transition from vegetative growth to reproductive growth, yet the involvement of miRNAs in these stages remains unknown. Therefore, we performed next generation sequencing of small RNAs profiles in crown tissues at three-leaf stage, winter dormancy stage, spring greenup stage and jointing stage.

Project description:Arbuscular mycorrhizal symbiosis is a predominant relationship between plant and arbuscular mycorrhizal fungi. To idendify arbuscular mycorrhiza responsive miRNAs, small RNA libraries were constructed in tomato roots colonized with Rhizophagus irregularis and without Rhizophagus irregularis. We identify miRNAs in tomato roots and provide a new profile of tomato miRNAs. And we found that some miRNAs were responsive to arbuscular mycorrhiza by comparing miRNAs in treatment with that in control.

The resulting symbiosis is called an arbuscular mycorrhiza and they are widespread in terrestrial ecosystems throughout the world. Significant alteration occurs at physiological and molecular levels in both symbionts. To gain a better understanding of the AM symbiosis, we use a 16000 feature oligonucleotide based array to examine gene expression in an arbuscular mycorrhizal symbioses, M. truncatula/Gigaspora gigantea.

Project description:Many plants associate with arbuscular mycorrhizal fungi for nutrient acquisition, while legumes also associate with nitrogen-fixing rhizobial bacteria. Both associations rely on symbiosis signaling and here we show that cereals can perceive lipochitooligosaccharides (LCOs) for activation of symbiosis signaling, surprisingly including Nod factors produced by nitrogen-fixing bacteria. However, legumes show stringent perception of specifically decorated LCOs, that is absent in cereals. LCO perception in plants is activated by nutrient starvation, through transcriptional regulation of Nodulation Signaling Pathway (NSP)1 and NSP2. These transcription factors induce expression of an LCO receptor and act through the control of strigolactone biosynthesis and the karrikin-like receptor DWARF14-LIKE. We conclude that LCO production and perception is coordinately regulated by nutrient starvation to promote engagement with mycorrhizal fungi. Our work has implications for the use of both mycorrhizal and rhizobial associations for sustainable productivity in cereals.
