Arabidopsis Transcriptome Data on ppGpp Signaling During Nitrogen Starvation

Table 1_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 last updated in April 2026, includes differential expression counts for thousands of nuclear-encoded genes under nitrogen-sufficient and nitrogen-deficient conditions.

Use Cases

• Identify differentially expressed genes based on transcriptome analysis comparing wild-type and quadruple mutant plants.
• Analyze transcription factor networks based on the description of 11 candidate master regulators.
• Study the coordination of nuclear and plastid gene expression based on data showing altered transcript levels in plastid-encoded genes.
• Investigate metabolic adaptation to nutrient stress based on gene expression changes associated with cell wall biosynthesis and defense responses.

Strengths

• Includes specific differential expression counts: 774 and 2,928 nuclear-encoded genes under +N and -N conditions, respectively.
• Focuses on a well-defined biological system: Arabidopsis mutants lacking all RelA-SpoT homologs (RSHs).
• Data is associated with a detailed research context described in the provided abstract.

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 at 166.4 KB, indicating limited scope.
