August 1997 in “The Plant Journal” 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.

November 1997 in “Planta” This study found that while a tip-focused calcium gradient influences localized growth in root hairs and pollen tubes, it is not the primary determinant of growth direction in root hairs of Arabidopsis thaliana.

March 2017 in “Molecular Plant” This study concluded that CNGC14 is a calcium-permeable channel crucial for polarized tip growth in Arabidopsis root hairs, but other channels may also influence the observed calcium influx.

March 1999 in “The Plant Journal” This study found that disrupting the microtubule cytoskeleton in Arabidopsis root hairs caused loss of growth directionality and suggested microtubules interact with calcium gradients to regulate apical growth stability.
July 2024 in “PLANT PHYSIOLOGY” 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.
