Origin of the epidermis in root meristems
New Phytologist, 1994SUMMARYA survey of root meristems shows that in general, closed meristems, those with separate regions generating outer and inner tissues, derive the epidermis with the cortex in monocotyledons and with the cap in dicotyledons. Open meristems, where the cells between the stelar pole and cap divide transiently producing an unstable boundary between the ...

Structural Problems at the Meristem [PDF]
Botanical Gazette, 1938 Problems of development dominate biology today. For the morphologist, the physiologist, and the geneticist it is the growing and differentiating organism, unfolding its innate capacities as it develops from fertilized egg to maturity, which occupies the center of attention.

Analyzing Floral Meristem Development
2010Flowers contain the male and female sexual organs that are critical for plant reproduction and survival. Each individual flower is produced from a floral meristem that arises on the flank of the shoot apical meristem and consists of four organ types: sepals, petals, stamens, and carpels.

Acta Biotheoretica, 1993
Apical cells are universally present in lower plants and their description has been mostly viewed morphologically as single-celled meristems. This study attempts to demonstrate that the roles of apical cells and more generally of meristems collectively are (a) often the proliferative source of all cells in a plant, (b) sometimes a formative centre in ...

Meristem in Osmunda cinnamomea
Botanical Gazette, 19311. The rhizome of Osmunda cinnamomea, when in the sporeling stage, grows by means of a tetrahedral apical cell. As the plant reaches maturity the segmentation of the apical cell becomes progressively less regular, in the majority of cases, until a condition is reached where the identity of the original apical cell is lost, and growth takes place by the

Function of plant shoot meristems
Seminars in Cell & Developmental Biology, 2001Growth and development of higher plants is directed by the continuous activity of meristems, sites of sustained cell division. Organs are formed at the flanks of the shoot meristem, while the central region contains pluripotent stem cells. The developmental programme of the meristem is coordinated by interactions between cells in separate regions of ...

Meristems: start your signaling
Current Opinion in Plant Biology, 2001All of the cells of the shoot apex are derived from a small number of stem cells in the center of the shoot meristem. Hence, cell lineage plays no role in establishing pattern formation or cell fate at the shoot apex. Growing evidence has implicated a number of cell signaling pathways in regulating shoot meristem development and organ formation.
