Spectinomycin, an inhibitor of plastid protein synthesis, can be used to mark specific cell
layers in the shoot meristem of Brassica napus. Pale yellow‐green (YG) plants resulting from …

We have generated a novel genetic system to visualize cell lineages in living tissues at high
resolution. Heat shock was used to trigger the excision of a specific transposon and …

In young sunflower leaves a cell differentiation gradient has been observed along the major
leaf where the leaf basal cells are less differentiated than the apical ones. The tip-base …

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 …

Plastids from cotyledons of sunflower (Helianthus annus L.) seedlings, germinated in the
dark or in the light, were isolated by isopycnic sucrose density gradient centrifugation. At all …

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 …

Guard cell and epidermal/subsidiary cell protoplasts obtained by enzymic digestion of
peeled Commelina communis leaf epidermis were separated and purified by discontinuous …

The division of plastids is an important part of plastid differentiation and development and in
distinct cell types, such as leaf mesophyll cells, results in large populations of chloroplasts …

The development of plastids in the palisade parenchyma cells of the cotyledons of mustard
seedlings (Sinapis alba L.) was studied by electron microscopy. In darkness the etioplasts …

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