Plant Gravity Perception Pilot: Arabidopsis RNA-Seq After Reorientation

RNA sequencing data from a study examining tissue-specific early transcriptional responses to gravity changes in Arabidopsis thaliana. The dataset was produced by the National Aeronautics and Space Administration and last updated in March 2026. Seedlings were grown for four days, reoriented 90 degrees for ten minutes, and RNA was extracted from four tissue fractions before sequencing via NovaSeq.

Use Cases

• Identify differentially expressed genes in response to gravity stimulus based on the described reorientation treatment.
• Compare transcriptional responses between wild-type and starchless mutant plants based on the pgm-1 mutant mentioned.
• Analyze tissue-specific gene expression patterns based on RNA extracted from root tips, mature root, hypocotyl, and cotyledon fractions.

Strengths

• Data originates from the National Aeronautics and Space Administration, a recognized authority in gravity-related research.
• Experimental design includes a clear control (vertical plants) and treatment (90-degree reorientation for ten minutes).
• RNA was sequenced via NovaSeq, a high-throughput sequencing platform.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality requires manual inspection after download.
