The cytoplast concept in dividing plant cells: cytoplasmic domains and the evolution of spatially organized cell division. American Journal of Botany 86 : 153 -172.Pickett-Heaps JD, Gunning BES, Brown RC, Lemmon BE, Cleary AL. 1999. The cytoplast concept in dividing plant cells: cytoplasmic ...
However, they do not need to differentiate into reproductive cells like those found in a flower. How is it that meristematic cells "know" what to become? The actively dividing cells of the apical meristem use positional cues such as hormones and cell-cell interactions as guides during ...
(Fig. 1-18). In time, these plantlets fall off the leaf and establish themselves as new plants. InBryophyllum,groups of cells at leaf margins are left undifferentiated to produce these plantlets; in others, seemingly mature cells at leaf margins or leaf surface resume meristematic activity ...
The second DNA repair pathway is homology directed repair (HDR) which relies on template DNA. Homologous recombination is an important process that occurs in somatic cells to repair DSBs and in meiotically dividing cells to exchange genetic material between parental chromosomes. The most common conser...
Differentiation-The cells from the root apical and the shoot apical and cambium mature to perform the functions. This is called maturation. Dedifferentiation-The cells which have lost the capacity of dividing and regains the capacity again under certain conditions known as Dedifferentiation. ...
cells that have differentiated into three types of tissues, that are going to continue in dividing/elongating until reaching a mature tissue are called? primary marriage stem procambium will become vascular tissue protoderm will become epidermis - most external lateral meristem- creates additional epide...
Cytokinins were discovered as a result of efforts to identify factors that would stimulate mature, nondividing plant cells to proliferate in tissue culture. Initially, Folke Skoog at the University of Wisconsin found a synthetic adenine derivative he named kinetin (Fig. 6.23) that was a powerful ...
The key to continued growth and repair of plant cells ismeristem. Meristem is a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. Apical meristemsare found at the apex, or tip, of roots and buds, allowing roots and stems to grow in leng...
This result matches past simulation results [17] and the current consensus that the cellulose orientation controls the growth direction in most plant cells [21]. In Eq. (57) that characterises the cell wall stress behaviour, the hotspots density's contribution (the χhot term) is controlled by...
long dividing phase of cells, cell wall damage by industrial equipment, genetic instability, light, wall adhesion, mixing, product secretion, and the varieties of cells present in the culture (Zhong, 2001; Smetanska, 2008). The last one can be addressed by identifying and selecting the cells...
