research Observations of Root Hair Patterning in Soils: Insights from Synchrotron-Based X-Ray Computed Microtomography
Root hairs in maize grow mainly in air-filled pores, limiting their role in nutrient uptake and plant anchorage.
research Plant Elicitor Peptides Regulate Root Hair Development in Arabidopsis
Peps help Arabidopsis plants grow more root hairs by affecting specific genes and calcium signaling.
research Neurogenic Inflammation in Stress-Induced Termination of Murine Hair Growth Is Promoted by Nerve Growth Factor
Stress increases a factor in mice that leads to hair loss, and blocking this factor may prevent it.
research Anti-Grey Hair Vitamin Deficiency in the Silver Fox
Lack of certain vitamins causes fur loss and greying in silver foxes.
