Genetic analysis reveals cellular differentiation proceeds independently of normal morphogenesis in Arabidopsis raspberry mutants, indicating distinct regulatory control during embryogenesis.

Key Points

To determine whether cell differentiation depends on normal morphogenesis during plant embryogenesis using Arabidopsis raspberry mutants.
Examined the morphological progression and cellular anatomy of wild-type and raspberry mutant (rsy1 and rsy2) Arabidopsis embryos using light and electron microscopy.
Assayed tissue-specific differentiation using cell-type-specific molecular markers, histochemical staining, and gene expression analysis across developmental stages.
raspberry mutant embryos arrested morphologically at the globular stage and failed to transition to the heart stage or form cotyledons.
Despite morphological arrest, mutant embryos correctly established distinct radial cell layers, including protoderm, ground tissue, and central vascular precursors.
