This study observed that while calcium influx does not initiate root hairs in Arabidopsis thaliana, it may be crucial for sustaining their elongation through elevated calcium levels at the root hair tip.

This study found that Arabidopsis thaliana mutants with altered AtRBOHC/RHD2 enzyme function showed abnormal protein regulation linked to increased drought sensitivity due to disrupted plasma membrane protein balance and cytoskeleton changes, as revealed through proteomic analysis and advanced microscopy.

In this study, wild-type Arabidopsis thaliana demonstrated increased phosphorus acquisition and growth compared to root hair mutants under low-phosphorus conditions.

This study showed that the zinc finger protein GIS3 is important for root hair growth in Arabidopsis by regulating RHD2 and RHD4 genes, with application of ethylene and cytokinin helping restore root hair presence in mutated variants.

This review highlights the role of reactive oxygen species in root hair growth and cell expansion in plants but does not report new empirical findings.
