research Chitosan Stimulates Root Hair Callose Deposition, Endomembrane Dynamics, and Inhibits Root Hair Growth

6 citations , September 2024 in “Plant Cell & Environment”

This study found that in Arabidopsis root hairs, mild chitosan treatment triggered callose deposition and slowed growth, while a higher concentration inhibited growth without callose deposition, indicating different responses based on chitosan concentration.

research Multiple Cyclic Nucleotide-Gated Channels Coordinate Calcium Oscillations and Polar Growth of Root Hairs

56 citations , April 2019 in “The Plant Journal”

This study found that CNGC 6, CNGC 9, and CNGC 14 are crucial for maintaining calcium oscillations necessary for normal root hair growth in plants, with mutations leading to defects like swelling and bursting.

research Early Arabidopsis Root Hair Growth Stimulation by Pathogenic Strains of Pseudomonas Syringae

24 citations , May 2017 in “Annals of botany”

This study found that root hair growth in Arabidopsis thaliana is stimulated by pathogenic Pseudomonas strains similarly to beneficial rhizobacteria, relying on ethylene signaling and an efficient exocyst-dependent secretory process.
