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.

,
May 2010 in “Plant Physiology” This study found that expressing certain PIN proteins in Arabidopsis root hairs inhibited growth by decreasing auxin levels, while PIN5 slightly stimulated growth, demonstrating differential effects on auxin transport.

December 2018 in “Plant, cell & environment/Plant, cell and environment” This study found that the PLC2 gene plays a critical role in auxin-mediated root development in Arabidopsis, influencing root growth and PIN2 distribution.
16 citations
,
September 2022 in “Plant Cell & Environment” This study suggests that iron influences auxin signaling through vesicle trafficking, particularly affecting PIN2 recycling, which may play a role in phosphate starvation-induced root hair growth in Arabidopsis.

January 2021 in “Plants” This review discusses the role of PIN-FORMED 2 and related signaling pathways in root hair growth regulation and reports no new experimental findings.
