Studysummary In this study, researchers identified a gene regulatory network in Arabidopsis that controls root hair growth under low-temperature conditions, revealing specific transcription factors and downstream targets that contribute to this growth response despite overall plant development being halted.

research Cell Surface Receptor Kinase FERONIA Linked to Nutrient Sensor TORC Signaling Controls Root Hair Growth at Low Temperature Linked to Low Nitrate in Arabidopsis Thaliana

44 citations , January 2023 in “New Phytologist”

This study found that low temperature triggers root hair elongation in Arabidopsis thaliana through a FERONIA-ROP2-TORC signaling pathway, also activated by nitrogen deficiency.

research Root Hair Defective Six-Like 4 (RSL4) Promotes Root Hair Elongation by Transcriptionally Regulating the Expression of Genes Required for Cell Growth

75 citations , July 2016 in “New phytologist”

This study found that RSL4 in Arabidopsis thaliana regulates genes necessary for root hair elongation by controlling proteins involved in cell signaling, cell wall modification, and secretion.
