Sample GSM7413152 Query DataSets for GSM7413152
Status Public on Jun 20, 2023
Title Eucalypt_Ctrl_JW28
Sample type SRA
 
Source name Root tissue (axenic)
Organism Eucalyptus grandis
Characteristics tissue: Root tissue (axenic)
cell type: Root
genotype: 2068
treatment: Axenic control
Treatment protocol Once the E. grandis seedlings were two months old and the fungal cultures had grown for one month, the plants were separated into one of three treatment categories: (1) fungal-free controls whereby the seedlings were transferred onto new half-strength MMN medium; (2) ‘pre-symbiosis’ which involved the transfer of seedlings onto new half-strength MMN medium in indirect contact with fungal mycelium for 24 h by separating the two organisms by a permeable cellophane membrane; (3) ‘physical contact’ seedlings were transferred onto new half-strength MMN medium and then placed into direct contact with the active growing edge of a fungal colony and then samples were harvested at 24 h, 48 h, 1 week, and 2 week post-contact. These plates were then closed using micropore tape to allow for gas exchange with the external environment.
Growth protocol Plants and fungus were grown on half-strength MMN medium ((pH 5.5; 1 g l−1 glucose) at 22–30°C night/day temperature with a 16 h light cycle.

Description Biol Rep 4
Data processing Paired-end Illumina reads were quality trimmed using the CLC Genomics Workbench tool version 11.0 (CLC Bio/Qiagen) removing ambiguous nucleotides as well as low quality read ends. The quality cutoff (error probability) was set to 0.05, corresponding to a Phred score of 13. Trimmed reads of >40 bases were mapped using the RNA-Seq Analysis 2.16 package in CLC requiring >80% sequence identity over >80% of the read length; strand specificity was omitted.
Genes with at least two-fold expression change and FDR value ≤<=0.05 were considered significant. Multidimensional scaling (“plotMDS” function in edgeR) was applied to visualize gene expression profiles. Expression heatmaps were generated by hierarchically clustering based on average linkage of FPKM values with heatmap.2 function from gplots package
To check reliability of both expression data, we used the superSeq package which uses a subsampling approach to simulate and predict the number of differentially expressed genes at lower read depths and random sampling points from the original dataset. These subsampled reads are then extrapolated to predict the relationship between statistical power and read depth.
Genes from the time-series in planta assay from both fungal and the plant side were clustered into co-expression based modules using STEM (v1.3.11)
