The capacity for sustained cell division within the plant meristem is a critical determinant of organ structure and performance. This capacity is diminished in mutants lacking the microtubule-associated protein CLASP and when brassinosteroid signaling is increased. Here, we discovered that CLASP is both targeted by and promotes activity of the brassinosteroid pathway in Arabidopsis root apical meristems.

- Researchers studied two mechanisms responsible for the export of GLL23, a lipase involved in glucosinolate metabolism in Arabidopsis thaliana, to prevent harmful accumulation in the endoplasmic reticulum (ER).
- Two mutant strains were identified: the nuclear cage (nuc) mutant, which showed large ER aggregates, and the cytoplasmic bodies (cyb) mutant with smaller compartments, indicating issues with GLL23 trafficking.
- The study found that the NUC protein, associated with myrosinase, and the CYB p24 protein, involved in cargo sorting, are crucial for the proper export of GLL23 from the ER, suggesting both a post-translational modification process is needed for its efficient transport.
