The basic body plan of a plant is established early in embryogenesis when cells
differentiate, giving rise to the apical and basal regions of the embryo. Using chlorophyll …

Imaging of chlorophyll autofluorescence by confocal microscopy in intact whole petals of
Arabidopsis thaliana has been used to analyze chloroplast development and …

In dicot plants, the process by which undifferentiated plastids, termed proplastids,
differentiate into mature functional chloroplasts begins in the shoot apical meristem (SAM) …

Here, we describe the development of chloroplasts and the buildup of the thylakoid
membranes in growing Arabidopsis leaves. Organelles were analyzed from three distinct …

Upon first exposure to light, plants initiate the synchronized biogenesis of chlorophyll and
thylakoid membranes. Two new studies have revealed a molecular view of the light …

Bundle sheath cells form a sheath around the entire vascular tissue in Arabidopsis leaves
and constitute a distinct leaf cell type, as defined by their elongate morphology, their position …

Plastids are an important group of plant cellular organelles and comprise one of the primary
features that distinguish plant cells from those of other eukaryotes. Plastids are thought to …

Chloroplasts of higher plants develop from proplastids, which are undifferentiated plastids
that lack photosynthetic (thylakoid) membranes. In flowering plants, the proplastid …

In most higher plants, mature dry seeds have no chloroplasts but etioplasts. Here we show
that in a hydrophyte, lotus (Nelumbo nucifera), young chloroplasts already exist in shoots of …
