Dissection of enhanced cell expansion processes in leaves triggered by a defect in cell proliferation, with reference to roles of endoreduplication.

Abstract excerpt

Leaf development relies on cell proliferation, post-mitotic cell expansion and the coordination of these processes. In several Arabidopsis thaliana mutants impaired in cell proliferation, such as angustifolia3 (an3), leaf cells are larger than normal at their maturity. This phenomenon, which we call compensated cell enlargement, suggests the presence of such coordination in leaf development. To dissect...
