March 2017 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that auxin regulates reactive oxygen species-mediated root hair growth by activating transcription factors and enzymes that affect cell elongation.
January 2018 in “bioRxiv (Cold Spring Harbor Laboratory)” This study explored how root hairs integrate opposing growth signals but did not report new conclusive findings on the activation of known molecular players in polar growth.
