Plant body clock shapes response to salt stress
WashU researchers report that salt changes the activity of the TIC clock protein in Arabidopsis, affecting protective genes. The findings suggest a research target for crop development, not a field-tested method.

Published: · Updated:
A study published October 14 in Science Advances by Washington University in St. Louis researchers found that salt exposure causes the Arabidopsis clock protein TIC to form small droplets in the cell nucleus. This clustering draws away some enzymes that suppress salt-protection genes, allowing those genes to become more active.
Plants without TIC were more vulnerable to salt under ordinary 24-hour cycles but handled it better under 21-hour light cycles matching their altered internal clock. The researchers say the link between the clock and stress response could inform future breeding or gene-editing work. The experiments used a model plant and did not demonstrate increased resilience in commercial crops.
