August 2008 in “Plant journal” D'orenone stops root hair growth by disrupting auxin transport, but adding auxin can reverse this.
July 2024 in “PLANT PHYSIOLOGY” This study identified CIPK13 and CIPK18 as genes specifically expressed in Arabidopsis root hairs, with double mutants showing reduced root hair length and growth rates. Calcium oscillations at the root hair tip were attenuated in these mutants compared to wild-type plants. Yeast two-hybrid screens revealed that CBL2 and CBL3 interact with CIPK13 and CIPK18, and mutants of cbl2 cbl3 displayed similar shortened root hair phenotypes. Biochemical assays confirmed the activation of CIPK13/18 by CBL2/3, suggesting that CBL2/3 and CIPK13/18 function as Ca2+-decoding modules in controlling root hair growth. This illustrates a molecular mechanism where the same CBLs recruit distinct CIPKs to regulate polarized tip growth in different plant cells.

July 2016 in “Molecular biology of the cell” A protein in plants needs to bind two lipids to help with root hair growth, and this process is similar across different plant species.
March 2021 in “Research Square (Research Square)” The SbbHLH85 protein helps sweet sorghum grow more root hairs but makes the plant more sensitive to salt.
