Description
Lucía Arenas-Alfonseca and three co-authors study a detox enzyme's second job in root hair growth in this 2023 paper. The enzyme, called CAS-C1, breaks down hydrogen cyanide in the plant Arabidopsis thaliana. Plants that lack it grow deformed root hairs, the tiny tubes that take up water and nutrients. The team sorted single root hair cells from normal and mutant plants and read their protein content. They also tracked a chemical tag that cyanide leaves on proteins.
The sorting and protein reads covered more than 3,900 proteins in root hairs. Mutant root centers and growth zones looked normal, even under nutrient stress. Several proteins tied to root hair growth carried the cyanide tag, among them parts of a known signaling path and of DNA methylation. The authors read this as evidence that cyanide based tagging helps steer hair growth.
