Note:

  • Follow examples of the gene ID format: AT2G14210 (Arabidopsis), FvH4_2g11353 (strawberry), Rid.02g074810 (raspberry), Prupe.1G489400 (peach), and MD02G1025500 (apple)










Comparative eFP Browser

Note:

  • The comparable stages among species are provided in the 'More - Tissue & Stage Comparison' page.

  • Please notice the scale bars that are different for each gene.










Consensus Network Summary


Note:

  • Overview of consensus co-expression network analysis result in the four species, noting the total number of genes in each genome, total number of co-expressed clusters in each species, and the unit of normalized gene expression for the network construction.





Cluster Eigengene Heatmaps

Note:

  • Hierarchical clustering of cluster eigengene in each species. Each row corresponds to a cluster, which is labeled with a unique number; each column corresponds to a specific tissue/stage. A cluster eigengene summarizes the expression of the gene cluster. The eigengene heatmaps allow users to select specific clusters based on their expression pattern for further analysis.

Genes in the cluster








Eigengene boxplot






Enriched GO

'Annotated' column indicates the number of genes in the genome that belong to the respective GO term, which is used to calculate the 'Expected' number of genes of the GO term in the cluster. The 'Significant' column indicates the observed number of genes in the cluster that belong to the respective GO term.







Network visualization (TF)





Note:

  • The network graph above is interactive. One can drag and rotate the nodes and zoom in or out of the graph.
  • Only the 100 strongest TF connections with correlation > 0.7 in the largest component (subnetwork) of the network are shown.
  • Click the grey download button to obtain a file that can be opened in Cytoscape. The file includes all the gene connections with correlation > 0.7 (TFs and non-TFs) in the largest component (subnetwork) of the network.
  • Larger node size correlates with a higher connectivity; the thicker edge correlates with a higher correlation co-efficient.



Tissue-specific Genes







Note:

  • TissueEnrich (Jain et al., 2019) was used to identify the genes that are specifically expressed in a tissue at certain stage (Tissue&Stage-Enriched) or the genes that are expressed in a specific tissue at multiple stages (Tissue-Enriched). Tissue- and stage-enriched genes are the genes with TPM >= 1 whose expression level in a particular tissue at a certain stage is at least two/five-fold higher than those in all other conditions (condition: combination of tissue and stage). Tissue-enriched genes are the genes that are not counted as tissue- and stage-enriched genes and are the genes with TPM >= 1 whose expression levels in a particular tissue at multiple stages are at least two/five-fold higher than those in all other conditions.

  • Strawberry fruit development: Stage 1(0 DPA), Stage 2(2-4 DPA), Stage 3(6-7 DPA), Stage 4(8-10 DPA), and Stage 5(10-13 DPA)

  • The downloaded table includes the information about the gene's best Arabidopsis BLAST hit (Arabidopsis gene ID, BLAST e-value, gene symbol, and gene description). The table also includes the expression of the gene in different samples. The explanation of the sample names can be found in the 'Sample Tables' section of the 'Download' page. And the expression values are TPM. The table of the tissue-enriched genes has an extra column called 'EnrichedStage'. This column shows the stages at which the genes are specifically expressed in a tissue.
