Arabidopsis Transcriptome Data on Plastidial Signaling During Nitrogen Starvation

Table 2_Loss of the plastidial signaling molecule, ppGpp, accumulation alters nuclear gene expression during nitrogen starvation.xlsx contains transcriptome analysis data from an Arabidopsis mutant study. The dataset, authored by Takanari Nemoto and shared under CC-BY-4.0, includes differential expression results for thousands of nuclear-encoded genes under nitrogen-sufficient and nitrogen-deficient conditions. It was last updated on April 20, 2026.

Use Cases

• Identify differentially expressed genes in Arabidopsis under nitrogen starvation based on transcriptome analysis.
• Study the role of the chloroplast alarmone ppGpp in nuclear gene reprogramming based on mutant vs. wild-type comparisons.
• Analyze transcription factor networks involved in nitrogen response based on the network analysis mentioned in the description.
• Compare expression patterns of plastid-encoded and mitochondrial genes under nutrient stress based on the transcript level findings.

Strengths

• Dataset is derived from a controlled experiment comparing a quadruple mutant lacking all RSHs to wild-type Arabidopsis.
• Analysis covers a significant number of genes, with 774 and 2,928 nuclear-encoded genes differentially expressed under +N and -N conditions, respectively.
• Includes network analysis identifying 11 candidate master regulators of transcription factor expression.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (34.6 KB), indicating it likely contains summary or processed results rather than raw sequencing data.
