RNAseq of Arabidopsis seedlings of either wt or hsl3-1, in response to a 30 minute treatment of 100 nM CTNIP4 relative to mock

ABSTRACT: In order to identify novel stress-induced signalling peptides, we searched for Arabidopsis thaliana transcripts encoding short proteins (<150 amino acids) with a predicted signal peptide, which were induced upon biotic elicitor treatment (Bjornson et al., 2021). Through this analysis, we identified an uncharacterised family of peptides with 5 predicted members, which we named CTNIP1 to 5 (pronounced catnip) based on relatively conserved residues within the peptides. CTNIP4 is perceived by Arabidopsis, inducing some hallmark outputs of defence (Pattern-Triggered Immunity) signalling. Mass spectrometric analyses indicated that HSL3 may be the receptor mediating CTNIP recognition. Through assaying transcriptomic responses in wild type and hsl3-1 mutants, we were able to confirm similarity of CTNIP and defence responses at the transcriptional level, and the dependence of these responses on HSL3.

Perception of a conserved family of plant signaling peptides by the receptor kinase HSL3

Project description:Plant genomes encode hundreds of secreted peptides; however, relatively few have been characterised. We report here an uncharacterised, stress-induced family of plant signalling peptides, which we call CTNIPs. Based on the role of the common co-receptor BRASSINOSTEROID INSENSITIVE 1-ASSOCIATED KINASE 1 (BAK1) in CTNIP-induced responses, we identified the orphan receptor kinase HAESA-LIKE 3 (HSL3) as the CTNIP receptor via a proteomics approach. CTNIP binding, ligand-triggered complex formation with BAK1, and induced downstream responses all involve HSL3. Notably, the HSL3-CTNIP signalling module is evolutionary ancient, predating the divergence of extant angiosperms. Definition of this signalling module will help establish its physiological role and provides a resource to understand further receptor-ligand co-evolution.

Identification of novel susceptibility factors in Arabidopsis towards necreotrophic fungal pathogens.

Project description:Transcriptional profiles were carried out for four transcription factors and two receptor-like kinases mutants, corresponding to genes that are co-expressed in silico with the CESA7 gene in Arabidopsis. These mutants show enhanced disease susceptibility to the necrotrophic fungal pathogen Plecthosphaerella cucmerina. Several gene families of small secreted peptides, some of them with known hormone or signalling implications, were commonly up-regulated in all of the 6 genotypes, unveiling a functional implication of these secreted peptides in the defence pathway against fungi. Transcriptomics of 6 mutant plants, including four transcription factors and two receptor-like kinases, were compared to their background Col-0 accession. For this porpoise, plants were grown as described and leaves from three plants of each genotype were mixed and extracted as one single replicate. Three replicates from three different sets of plants were analysed for each genotype.

Total mRNA sequence dataset from Pectobacterium atrosepticum colonising potato or radish roots

Project description:Pectobacterium atrosepticum (Pba) is a gram-negative bacterium which causes blackleg and tuber soft rot on potato. To investigate the molecular processes and responses involved in Pba-host (potato) and Pba-non-host (radish) interactions, under laboratory conditions, we used total RNA-sequencing to measure the gene expression patterns from all three species. Samples from infected and non-infected plant roots were collected after fourteen days of inoculation with Pba SCRI_1039 and subjected to total RNA-sequencing on an Illumina sequencing platform.

Retrograde signalling during caused by heritable mitochondrial dysfunction is partly mediated by ANAC017 and improves plant performance.

Project description:Mitochondria are crucial for plant viability and are able to communicate information on their functional status to the cellular nucleus via retrograde signalling, thereby affecting gene expression. It is currently unclear if retrograde signalling in response to constitutive mitochondrial biogenesis defects is mediated by the same pathways as those triggered during acute mitochondrial dysfunction. Furthermore, it is unknown if retrograde signalling can effectively improve plant performance when mitochondrial function is constitutively impaired. Here we show that retrograde signalling in mutants defective in mitochondrial proteins RNA polymerase rpotmp or prohibitin atphb3 can be suppressed by knocking out the transcription factor ANAC017. Genome-wide RNA-seq expression analysis revealed that ANAC017 is almost solely responsible for the most dramatic transcriptional changes common to rpotmp and atphb3 mutants, regulating both classical marker genes such as alternative oxidase 1a (AOX1a) and also previously-uncharacterised DUF295 genes that appear to be new retrograde markers. In contrast, ANAC017 does not regulate intra-mitochondrial gene expression or transcriptional changes unique to either rpotmp or atphb3 genotype, suggesting the existence of currently unknown signalling cascades. The data show that the role of ANAC017 extends beyond common retrograde transcriptional responses and affects downstream protein abundance and enzyme activity of alternative oxidase, as well as steady state energy metabolism in atphb3 plants. Furthermore, detailed growth analysis revealed that ANAC017-dependent retrograde signalling provides benefits for growth and productivity in plants with mitochondrial defects. In conclusion, ANAC017 plays a key role in both biogenic and operational mitochondrial retrograde signalling, and improves plant performance when mitochondrial function is constitutively impaired.

The effect of sucrose and sulfamethoxazole on the Arabidopsis transcriptome

Project description:A chemical screen was performed in search of compounds that modify plant responses to sucrose. This screen uncovered that sulfamethoxazole (SMX), a folate biosynthesis inhibitor, acted synergistically with sucrose to inhibit hypocotyl elongation, suggesting interaction between these two pathways. Transcriptome analysis was performed to identify changes in transcript abundance that may underpin crosstalk between sucrose and SMX. Three-day-old dark-grown seedlings were treated to sucrose and SMX at concentrations that induced no change in hypocotyl elongation when administered independently, yet restricted elongation when both were present in the growth media (10mM and 0.2µM, respectively). This analysis uncovered multiple core auxin signalling components that exhibit altered transcript abundance in response to co-treatment with sucrose and SMX, suggesting that auxin signalling mediates crosstalk between these two pathways. This study highlights an input through which metabolic status can shape plant growth and development through hormone signalling. 12 arrays total. Three arrays as non-treated control, three arrays from seedlings raised in presence of 0.2µM SMX, three arrays from seedlings raised in presence of 10mM sucrose, and three arrays from seeldings raised in presence of both 10mM sucrose and 0.2µM SMX. Three biological replicates were produced for each growth treatment.

Transcription profiling of WT and dsr1 Arabidopsis seedlings treated with salicylic acid

Project description:Reactive oxygen species such as hydrogen peroxide (H2O2) are important in biotic and abiotic stress responses in plants, but their source is often unclear. We have identified an Arabidopsis mutant that shows loss of stress responsive GSTF8 gene expression in response to the plant defence signal salicylic acid (SA) . The mutant showed increased susceptibility to both fungal and bacterial pathogens. The dsr1 mutation was mapped to mitochondrial succinate dehydrogenase (SDH1-1) and dsr1 had reduced SDH activity and a lowered mitochondrial H2O2 production. To better understand the loss of SA-response in dsr1, we performed ATH1 microarray analysis in WT and dsr1 10 hours after a 1 mM SA treatment, a point at which we observed maximal SA-induced GSTF8 promoter activity. 4 day old WT (a Columbia line containing a -800GSTF8::LUC reporter) and dsr1 seedlings (a mutant Columbia line containing a -800GSTF8::LUC) reporterwere treated with water (mock) or 1 mM SA for 40 min. Ten hours after treatment, samples were collected.

Arabidopsis thaliana Col-0 leaf transcriptome response to Agrobacterium tumefaciens C58

Project description:As sessile organisms, plants require dynamic pathways in order to recognize pathogens and coordinate plant defenses by signalling. Agrobacterium tumefaciens C58 is able to avoid triggering plant defenses prior to entering the cell, and therefore is only detected once infection has begun making Agrobacterium a plant pathogen to numerous plant species. Understanding plant responses to Agrobacterium will be useful in improving plant defenses and potentially may also improve plant transformation efficiency. Microarrays were utilized for detailing the global gene expression pattern in A. thaliana Col-0 leafs in response to A. tumefaciens C58 for the identification of differentially expressed genes. 3-week-old A.thaliana Col-0 seedlings were selected for growth in hydroponic systems. A. tumefaciens C58 was inoculated into the hydroponic system and co-cultivation persisted for 8 hours. Leaf tissue was seperated for RNA extraction and hybridization to the ATH1 Affymetrix microarray.

RNAseq of camta3/dsc1/dsc2 after elf18 or mock treatment, against wt control, at 10, 30 and 90 minutes

Project description:The general stress response is a major transcriptional reprogramming in elicitor response. CAMTA3 is a key regulator of the general stress response, and is guarded by Dominant Suppressor of CAMTA3 1 and DSC2. Here we assay transcriptional response to elf18, an elicitor, at 10 (primary response), 30 (major GSR) and 90 (beginning to be immunity-specific responses) minutes, in wt and in a line mutated in camta3/dsc1/dsc2, thus losing the GSR with only partial autoimmune activation.
