RNA sequencing (RNA-seq) for identifing differentially expressed transcription factor genes during early plant growth

ABSTRACT: The purpose of this study is to identify differentially expressed transcription factor genes during early plant growth. A total amount of 3 µg RNA per sample was used as input material for the RNA sample preparations. Sequencing libraries were generated using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (NEB, USA) following manufacturer’s recommendations and index codes were added to attribute sequences to each sample. We used an optimized data analysis workflow, and mapped about 45 million sequence clean reads per sample to the Arabidopsis genome and identified 33,685 transcripts in 2 and 6 dpg (day post germination) old wild type plant (Col-0). Among them, there are 9321 genes differentially expresses from 2- and 6-d-old plants, and 479 differentially expresses transcription factor (TF) genes. Of these genes, 344 TF genes up regulated and 135 down regulated in 6-d-old plants compared with 2-d-old plants, with a fold change ≥2, ≤0.6 and p value <0.05. The P values were adjusted using the Benjamini & Hochberg method. Corrected P-value of 0.005 and log2(Fold change) of 1 were set as the threshold for significantly differential expression. This study will facilitate analysis related with developmental study in early plant growth stage.

Next Generation Sequencing to Study FLK-affected genes

Project description:Purpose: The goals of this study are to compare RNA-seq profiles of Col-0, acd6-1, flk-1, flk-5, acd6-1flk-1, and acd6-1flk-5 to identify genes affected by FLK. Methods: Total RNA was extracted from 25-d old plants. A total amount of 1 μg RNA per sample was used to generate cDNA libraries, using NEBNext® UltraTM RNA Library Prep Kit for Illumina® (NEB, USA) following manufacturer’s recommendations. Deep sequencing was performed using Illumina NovaSeq 6000 (Novogene Corporation Inc.). Triplicate biological samples were used for all genotypes except acd6-1flk-5, which had duplicate samples because one sample failed to pass quality control. The samples were multiplexed and sequenced with the standard paired-end sequencing that has a read length of 150bp per end and 20M reads per end per sample. Results: We found that over 8000 genes are differentially affected by FLK based on the RNAseq analysis. GO analysis revealed that FLK-affected genes are enchriched for genes involved in primary metabolism and in response to abiotic and biotic stimuli. Conclusions: The RNAseq analysis support a role of FLK in regulation of plant development and defense.

Salt-stress and CTD phosphatase-like 4 mediate switching of snRNA to mRNA transcription in Arabidopsis thaliana [im-nc]

Project description:RNA polymerase II C-terminal domain (CTD) phosphorylation regulates transcription of both protein-coding mRNAs and non-coding RNAs (ncRNAs). However, understanding about CTD-phosphoregulation in plant ncRNA transcription is still obscure. Here we used Arabidopsis CTD phosphatase-like 4 knock-down lines (CPL4RNAi) and show that CPL4 functions in a genome-wide, conditional 3'-extensions of small nuclear RNA (snRNA) and biogenesis of novel snR-DPGs, which are protein-coding snRNA-mRNA fusion transcripts (snR-Downstream Protein-coding Gene). Production of snR-DPG is dependent on pol II snRNA promoter (PIIsnR), and CPL4RNAi promotes readthrough of snRNA 3’-end processing signal and pol II transcription downstream of snRNA. Also discovered was a novel unstable ncRNASSP14, which is driven by a PIIsnR and is conditionally 3'-extended to produce mRNA. In wild type, the snRNA-to-snR-DPG switching is induced by salt stress, and is associated with alteration of CTD phosphorylation status in the transcribing pol II complex. The snR-DPG transcripts occur widely in plants, suggesting that the transcriptional snRNA-to-snR-DPG switching is a previously unknown mechanism ubiquitous in plants to regulate gene expression in response to environmental stresses.

Expression data from 10-day old Arabidopsis seedlings treated with protease IV from Pseudomonas aeruginosa PA14

Project description:Immune responses in plants are triggered in part by conserved microbe-associated molecular pattern (MAMP) molecules such as bacterial flagellin. Upon MAMP perception, plants rapidly turn on the induction of numerous defense-related genes. We have identified a novel type of plant innate immunity elicitor, protease IV from Pseudomonas aeruginosa. Genome-wide transcriptomic profiles obtained with Affymetrix Arabidopsis ATH1 GeneChips® of 10-day old Arabidopsis seedlings treated with 20 nM purified protease IV for 1 hour were compared to published bacterial flagellin- and oligogalacturonide-triggered responses. We used microarrays to characterize the global transcriptomic changes in Arabidopsis seedlings upon protease IV treatment.

Plant development on ISS differes from the development on the ground and is influenced by the genetic background.

Project description:The development of Col-0 and WS plants on orbit differs from that on the ground as demonstrated by the comparison of the gene expression profiles between 4 days old to 8 days old plant in the two environments. The Col-0 plants used different genes reflecting different physiological processes than WS plants, suggesting the role of the genetic background in the developmental decisions. The 4 days old Col-0 plant in orbit showed deficit in wax and suberin production relatively to the 8 days old plants, the difference unregistered on the ground. There was more dramatic difference in the overexpression of the root system development and anatomical structure development genes in 8 days old plants than in 4 days old plant in both genotypes on the ground than in flight, implying smaller root developmental gap between 4 days and 8 days old roots in orbit. The WS plant uniquely showed overexpression of the photosynthesis related genes in the 4 days old roots relative to 8 days old root in the spaceflight environment but not on the ground. The seeds germinated in the novel growth environment of ISS implemented different developmental strategies as captured by the genes expression patterns, than seeds developing on the ground.

Rice gene global expression during nonhost interaction with Blumeria graminis f. sp. hordei (Bgh)

Project description:Powdery mildew is a very common plant disease and only few plants are immune. Host interactions have been identified and characterized for the pathosystems barley-B. graminis f. sp. tritici (Bgt) and wheat-B. graminis f. sp. hordei (Bgh), whereas no data are reported about powdery mildew and nonhost plants, such as rice. On the other hand rice nonhost resistance is widely unexploited and only few expression data are available. To characterize rice response during nonhost interaction with Bgh, a global expression analysis was performed by using the GeneChip® Rice Genome Array. To describe rice gene expression profiles during nonhost interaction, 2 week-old rice plantlets were inoculated with Bgh. Treated (inoculated) and control (mock) samples were collected 24 hours post-inoculation for GeneChip® Rice Genome Array hybridization.

During development, the Sku6 mutant roots engage different genes than wild type Col-0 roots, either on the ground or in spaceflight.

Project description:The wild type Col-0 plants and the Sku-6 mutant plants of the Col-0 background were germinated on ISS or on the ground and the gene expression profiles in roots at 4 days or 8 days were established. The Sku6 gene (At2g03680) codes for a protein that localizes to microtubule within the cortical array and putatively acting as an intramolecular linker. The development of Col-0 and Sku-6 plants on orbit differs from that on the ground as demonstrated by the comparison of the gene expression profiles between 4 days old to 8 days old plant in the two environments. However the development of Sku-6 mutant plants also differs from Col-0 at either age and in either environment, suggesting the role of the genetic background in these developmental decisions. The 4 days old Sku-6 roots in orbit engaged more genes than the 4 days old Col-0 roots in orbit but also more than the 4 days old Sku-6 roots on the ground. Overall the 4 days old roots differentially expressed more genes in spaceflight relative to ground than the 8 days old roots of either genotype.

Transcriptomic analysis of regulatory gene expression profiles by EIJ1 under Pst D3000 treatments

Project description:To understand how the EIJ1 complex functions in plant innate immunity, a genome-wide transcriptomic analysis was carried out using 3-week-old of eij1-1 and Col plants under dip inoculated with Pst DC3000 (OD600 = 0.1) treatment. Basing on the criteria of 2-fold cutoff for the genes with 5% false discovery rate, we first identified the differentially expressed genes in eij1_P vs Col_P, which are referred to stress response and innate immune response. These data suggest that EIJ1 may be involved in plant immune response.
