This article reviews how calcium and reactive oxygen species gradients and oscillations interact to promote root hair cell expansion and reports no new experimental findings.

In this study on Arabidopsis, the researchers identified CIPK13 and CIPK18 as crucial genes for root hair growth, finding that deficiencies in these genes resulted in shorter root hairs and reduced growth rates due to altered calcium oscillations.

This study found that D'orenone blocks root hair growth by increasing PIN2 protein abundance, leading to reduced auxin concentration, but external auxin can reverse these effects.

This review outlines the factors controlling root hair growth in plants, emphasizing the coordinated roles of cellular and extracellular components, without reporting new experimental results.
