Project description:Sclerotinia sclerotiorum, the causal agent of white mould, is a necrotrophic fungal pathogen responsible for extensive crop loss. Current control options rely heavily on the application of chemical fungicides that are becoming less effective and may lead to the development of fungal resistance. In the current study, we used a foliar spray application of boron to protect Brassica napus (canola) from S. sclerotiorum infection using whole plant infection assays. Application of boron to aerial surfaces of the canola plant reduced the number of S. sclerotiorum forming lesions by 87% compared to an untreated control. We used dual RNA sequencing to profile the effect of boron on both the host plant and fungal pathogen during the infection process. Differential gene expression analysis and gene ontology term enrichment further revealed the mode of action of a foliar boron spray at the mRNA level. A single foliar application of boron primed the plant defense response through the induction of genes associated with systemic acquired resistance while an application of boron followed by S. sclerotiorum infection induced genes associated with defense-response-related cellular signalling cascades. Additionally, in S. sclerotiorum inoculated on boron-treated B. napus, we uncovered gene activity in response to salicylic acid breakdown, consistent with salicylic-acid-dependent systemic acquired resistance induction within the host plant. Taken together, this study demonstrates that a foliar application of boron results in priming of the B. napus plant defense response, likely through systemic acquired resistance, thereby contributing to increased tolerance to S. sclerotiorum infection.

Project description:Poplars are known to be highly tolerant species to boron toxicity and accumulation. However, genes and molecular networks responsible in boron toxicity tolerance have not been investigated yet. Therefore, we performed a pot experiment with 20 black poplar clones collected from the vicinity of boron mines and polluted areas to investigate its potential role in phytoremediation and to select the most boron toxicity tolerant genotype. Trees were treated with irrigation water containing seven elevated boron concentrations from 0 to 160 ppm. Then a microarray based comparative transcriptome profiling was conducted to identify boron toxicity regulated genes responsible in defence responses of black poplar. The results of the study indicated that black poplar is quite suitable for phytoremediation of boron pollution. It could resist 15 ppm soil B content and < 1600 mg/kg boron accumulation in leaves which are highly toxic concentrations for almost all agricultural plants. Transcriptomics results of study revealed totally 1625 and 1419 altered probe sets under boron toxicity in leaf and root tissues, respectively. The highest induction were recorded for the probes sets annotated to tyrosine aminotransferase, ATP binding cassette transporters, glutathione S transferases and metallochaperone proteins. Strong up regulation of these genes attributed to internal excretion of boron into the cell vacuole and existence of detoxification processes in black poplar. Many candidate genes functional in signalling, gene regulation, antioxidation, boron uptake, transport and detoxification processes were also identified in the current study. This is the first transcriptomic study identifying boron toxicity regulated poplar genes and their potential role in boron toxicity tolerance.

Total RNA used in microarray experiment was isolated from the leaves and roots of black poplar clone; N.92.237 which accumulated the highest amount of boron its tissues. Total RNA used in the microarray experiment was isolated from leaves and roots of three black poplar saplings grown in ~ 2 ppm (control) and ~ 15 ppm (toxic) soil B contents. RNA isolation was made according to Lithium chloride precipitation method described in Chang et al. (1993). These three isolated RNAs (biological replicates) for each tissue loaded onto three Affymetrix poplar Gene Chips (technical replicates). Totally, 12 GeneChips (2 tissues Ã? 2 different B treatment Ã? 3 biological replicates) were used for transcriptional analysis.

Project description:Boron is essential for plants, and boron availability in soil is an important determinant of agricultural production. Boron availability in soil is limited at many regions in the world, including Japan. Under boron deficient conditions, leaf expansion and root elongation, apical dominance, flower development,and fruit and seed sets are inhibited. In this work, we analyzed the mRNA expression of genes containing AUGUAA motif in their 5′-UTR, which is induced by boron. We used microarrays to detail the global gene expression underlying boron deficiency in roots.

Under boron deficient conditions, leaf expansion and root elongation, apical dominance, flower development,and fruit and seed sets are inhibited.

We used microarrays to detail the global gene expression underlying boron deficiency in roots. Plants were grown on solid medium containing 1% (w/v) sucrose, 1.5% (w/v) gellan gum and 100 M-BM-5M boron for 10 days and then transferred to 0.3 and 100 M-BM-5M boron for 2 days. Plates were placed vertically at 22M-BM-0C in a growth chamber under long-day conditions (16 h light/8 h dark cycle). We analyzed the transcript profiles in roots by microarray analysis (Affymetrix ATH1 Genome Array).

Project description:We previously reported that ribosome stalling at AUG-stop sequences in the 5'-UTR plays a critical role in regulating the expression of Arabidopsis thaliana NIP5;1, which encodes a boron uptake transporter, in response to boron conditions in media. Here, we conducted ribosome profiling analysis to reveal the genome-wide regulation of translation in response to boron conditions in A. thaliana. We identified 460 translationally regulated genes. Transcripts with reduced translation efficiency were rich in upstream open reading frames (uORFs), highlighting the importance of uORF-mediated translational regulation. We found that 148 uORF instances had greater ribosome density under high boron conditions. Moreover, translationally downregulated transcripts were rich in minimum uORFs (AUG-stops), suggesting that AUG-stops play a global role in the boron response. Boron increased the ribosome occupancy of stop codons, indicating that this element is involved in global translational termination processes.

Project description:Boron is an essential micronutrient for plants and is taken up in the form of boric acid (BA). Despite this, a high BA concentration is toxic for the plants, inhibiting root growth and is thus a significant problem in semi-arid areas in the world. In this work, we report the molecular basis for the inhibition of root growth caused by boron. We used microarrays to detail the global gene expression underlying boron toxicity in roots.
