Most plant cells are characterized by the presence of a large central vacuole that in differentiated cells accounts for more than 90% of the total volume. We have undertaken a genetic screen to look for mutants that are affected in the formation of vacuoles in plants. In this study, we report that inactivation of the Arabidopsis gene VACUOLELESS1 (VCL1) blocks vacuole formation and alters the pattern of cell division orientation and cell elongation in the embryo. Consistent with a role in… CONTINUE READING
