This study found that in wild-type Arabidopsis plants, root hair growth is suppressed with increased nutrient availability, with RHD6 subfamily genes down-regulated and GTL1 and DF1 genes influencing root hair morphology under these conditions.

This study identified the NAC transcription factor RD26 as a critical regulator of drought-induced root hair growth restriction in Arabidopsis thaliana, with a similar mechanism observed in tomatoes, indicating evolutionary conservation.

In this study, researchers identified a temperature-sensitive mutation in the FERONIA gene of plants that prevents root hair formation at elevated temperatures, highlighting its role in maintaining root hair growth and response to plant hormones.

This study found that phosphorus and nitrogen deprivation increased root hair length in Brassica carinata and induced the expression of certain P-responsive genes, such as LRR and PRP.

In this study, researchers found that the efflux of calcium in root hairs of Arabidopsis thaliana, particularly through the ER-localized ACA2 and ACA7, is crucial for modulating cytoplasmic calcium signals and enabling proper root hair growth, with disruptions leading to impaired elongation.

This study demonstrated that MYB83 plays a crucial negative role in ethylene-mediated root hair growth in Arabidopsis by directly inhibiting EIN3, and that manipulating the MYB83-EIN3 interaction is key to root hair development and plant tolerance to nutrient stress conditions.

In this study, rice straw-derived smoke water enhanced root growth in rice plants by increasing root meristem size and cell proliferation, reducing superoxide accumulation under phosphorus deficiency, and altering internal phosphorus partitioning, although it suppressed root hair elongation, which affected phosphate uptake.

This study found that in Arabidopsis, root hair-specific proteins ADF8 and ADF11 are crucial for responding to hormonal signals like auxin and ethylene, which in turn modulate actin filament dynamics and are key for root hair growth under various environmental conditions.

This study found that overexpressing the CLE peptide SlCLE10 in tomatoes increased root hair length and improved drought tolerance, suggesting its potential for enhancing crop resilience to osmotic stress.
