Arabidopsis Root Cell Expansion Data via Apoplastic pH Regulation

Data from a study using the fluorescent pH indicator HPTS to investigate auxin's role in apoplastic pH regulation and cellular expansion in Arabidopsis thaliana roots. The findings suggest a complex, concentration-dependent role for auxin in steering root cell expansion and gravitropic response. The dataset includes experimental measurements related to auxin signaling, apoplastic pH, and cellular elongation.

Use Cases

• Analyze correlations between apoplastic pH measurements and cellular elongation rates to test the acid growth theory in roots.
• Model the concentration-dependent effects of endogenous and exogenous auxin levels on transient alkalinization of the extracellular matrix.
• Investigate the role of the receptor-like kinase FERONIA in physiological processes affecting root expansion during gravitropic response using associated experimental data.

Strengths

• Data supports a novel application of the HPTS fluorescent indicator for assessing apoplastic pH at cellular resolution in plant roots.
• Findings are published and relate to a heavily debated model (acid growth theory) in plant biology, providing specific experimental evidence.

Limitations

• The dataset scope is confined to the model organism Arabidopsis thaliana, limiting direct applicability to other plant species.
• Specific technical details on data volume (rows/columns), file formats, and sample data are unavailable for assessment.
