BRAKERKREP00000016247.1.Transcript abundance of BRAKERKREP00000016247.1 across 29 RNA-seq samples of Hydra viridissima. This gene has no row in the species' RNA-seq expression matrix, so every value below is shown as zero — the matrix simply does not cover this transcript. Values are TPM (transcripts per million) from the StringTie quantification; one bar is one sample, grouped and coloured by condition, sorted by expression within each group.

Source: CnidoSite RNA-seq expression matrices (HVIRI_TPM,
StringTie quantification over 29 runs), joined to SRA sample
metadata. Samples whose tissue/treatment is not recorded in the source metadata are grouped
by the descriptor carried in the expression matrix itself.
Genes whose expression across the transcriptome samples of Hydra viridissima tracks this one. Counts are over the whole network; the network view itself draws at most 100 partners per query gene (CNIDO_NET_TOP_K), so a hub gene can show fewer edges than the number below.
| Direction | Partners | Most correlated partner | PCC |
|---|---|---|---|
| Positively correlated | 0 | not in this network | - |
| Negatively correlated | 0 | not in this network | - |
This gene has no edge at all in the Hydra viridissima network, in either direction — it is not one of the genes the network was built from (the network covers genes with enough expression variation across the transcriptome samples). The counts above are a property of the network, not a failed lookup.
Open this gene in Network Analysis → The network opens with the gene already entered and both directions selected. There you can add up to 9 more genes, switch between the positive and negative network, and export the edge list.
Whether this gene can be visualised in the single-cell atlases of Hydra viridissima, and in which cell types it is a marker. Expression is stored per cell, so the violin plot and the cell-type means are computed in the viewer — open a dataset to see them.
No single-cell dataset has been published for this species. The atlases that do exist are listed in the Cell Atlas.
Chromatin and DNA-methylation data covering this gene. Peak calls are listed per sample with the genomic region the peak falls in; DNA methylation is listed as sample availability only, because those tables are queried by the DNA Methylation page itself.
No epigenomic data has been deposited for this species. The assays that exist across the site are described in the Epigenomic Data module.
Every tool below opens with this gene already entered, so you land on the analysis rather than on an empty form. Links open in a new tab.
