Abstract: Glucose has been documented to play roles in plant growth and development, while its role in root elongation remains elusive. Our study demonstrates that high concentrations of glucose reduce the size of the root meristem zone by repressing PIN1 accumulation and thereby reducing auxin levels. ABA INSENSITIVE 5 ( ABI5 ) also involves in this process by modulating glucose‐regulated PIN1 accumulation . Taken together, our data suggest that ABI5 functions in the glucose‐mediated inhibition of the root meristem zone by repressing PIN1 accumulation, thus leading to reduced auxin levels in roots.
