Building a root: the control of patterning and morphogenesis during root development.
Roots are plant organs adapted to acquire water and nutrients from the environment. The rapid exploratory growth habit of roots makes them well suited for experimental studies of organogenesis in plants. In this regard, one particularly advantageous feature of root development is that tissues and cell types arise from an apical meristem that is relatively simple in structure. Moreover, root dev...
متن کاملThe regulation and plasticity of root hair patterning and morphogenesis.
Root hairs are highly specialized cells found in the epidermis of plant roots that play a key role in providing the plant with water and mineral nutrients. Root hairs have been used as a model system for understanding both cell fate determination and the morphogenetic plasticity of cell differentiation. Indeed, many studies have shown that the fate of root epidermal cells, which differentiate i...

15 صفحه اولRoot patterning: SHORT ROOT on the move
The radial pattern of the plant root is determined by the action of two transcription factors, SHORT ROOT and SCARECROW, which are produced in different cell types. The SHORT ROOT protein has now been shown to move from cell to cell, regulating transcription of the downstream SCARECROW gene in the target cells.
متن کاملARABIDOPSIS HOMOLOG of TRITHORAX1 (ATX1) is required for cell production, patterning, and morphogenesis in root development
Arabidopsis homolog of trithorax1 (ATX1/SDG27), a known regulator of flower development, encodes a H3K4histone methyltransferase that maintains a number of genes in an active state. In this study, the role of ATX1 in root development was evaluated. The loss-of-function mutant atx1-1 was impaired in primary root growth. The data suggest that ATX1 controls root growth by regulating cell cycle dur...
