New Phytologist, Volume 248, Issue 5, Page 2444-2465, December 2025.Summary To improve plant tolerance to suboptimal availability of the micronutrient boron (B), it is crucial to understand the mechanisms plants have evolved to tolerate B‐limited conditions. We assessed temporal physiological, ionomic and molecular responses to B deficiency across 185 Arabidopsis thaliana accessions grown in soil‐substrate in an ...

Coordination of cortex modifications in time, space, and under stress
New Phytologist, Volume 248, Issue 4, Page 1677-1685, November 2025.Summary In roots, cell‐type‐specific differentiation enables specialized responses to environmental stress. The cortex, located between the vasculature and epidermis, is a key site for stress‐responsive modifications. The distinct specializations of the cortex are controlled by developmental, positional and environmental signals.
