Extended Data Fig. 10: Salt stress promotes ABA accumulation in root tips and inhibits root cap growth.

a, ABA accumulation in root cap cells and epidermal cells measured using the FRET sensor nlsABACUS2-400n with or without 200 mM NaCl treatment for 30 min. Scale bars, 10 μm. ABA accumulation was quantified. Error bars denote ±s.e.m., n=10 plants. **** P < 0.0001 (statistical significance determined by two-tailed non-paired Student’s t test). b, Treatment with 200 mM NaCl for 24 h severely inhibited root cap cycle in 5-day-old WT plants. Scale bars, 10 μm. All results are reproducible from at least three independent experiments.
