May 2008 in “Plant journal” 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.

August 2022 in “Plant Signaling & Behavior” This study found that certain growth media combinations influence the development of Arabidopsis thaliana root hairs, identifying specific conditions that promote the growth of the longest root hairs.

June 2014 in “PLANT PHYSIOLOGY” This study found that Arabidopsis mutants with disrupted auxin conversion pathways displayed low auxin phenotypes and increased biosynthetic gene expression, suggesting a feedback mechanism maintains auxin homeostasis.
December 2022 in “Frontiers in plant science” This study identifies two new proteins, CCDC22 and CCDC93, essential for root and root hair growth in Arabidopsis, and demonstrates their genetic link to a VTI13-dependent vacuolar trafficking pathway.

October 2003 in “Development” This study found that different stabilizing mutations in Aux/IAA proteins affect root hair development in Arabidopsis by disrupting the auxin response and suggest a model where the relative abundance of these proteins determines root hair initiation.
