April 2014 in “The Plant cell” In this study, researchers showed that the CAP1 gene regulates root hair growth in plants by modulating cytoplasmic ammonium levels and maintaining calcium gradients, highlighting its role in ammonium homeostasis.
356 citations
,
March 2012 in “Trends in Plant Science” This review discusses the crosstalk between auxin and ethylene in seedling growth and development, emphasizing how ethylene modulates auxin's effects across different tissues.
122 citations
,
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.
512 citations
,
February 2008 in “Science” In this study, researchers found that a positive feedback loop involving Ca 2+ and RHD2 NADPH oxidase-derived ROS helps maintain growth sites, crucial for root hair development and cell shape in Arabidopsis thaliana.
229 citations
,
May 2006 in “Journal of Experimental Botany” This review highlights the role of reactive oxygen species in root hair growth and cell expansion in plants but does not report new empirical findings.
157 citations
,
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.
141 citations
,
June 2002 in “Philosophical Transactions of the Royal Society B Biological Sciences” This review discusses recent physiological and genetic advances in understanding tip growth in Arabidopsis thaliana root hairs and reports no new experimental results.
189 citations
,
July 2000 in “American Journal of Botany” In this study, wild-type Arabidopsis thaliana with responsive root hairs efficiently acquired phosphorus under low-phosphorus conditions compared to mutants, suggesting an adaptive advantage in nutrient-limited environments.
200 citations
,
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.
317 citations
,
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.
578 citations
,
May 1996 in “Plant Cell & Environment” This study found that Arabidopsis thaliana plants developed longer root hairs under low phosphorus conditions, suggesting auxin involvement in this adaptive response.
