    This book is a definitive overview of the ‘state of the art’ in cell biology. It is based on papers presented by leading researchers at the Spanish Society for Cell Biology’s XIV Congress. In the much larger roots of Zea, the relative elemental rate of elongation is at a maximum of hrr 1 at about 4 mm. from the tip of the root cap, and of cell division, hr. -1 at about mm. The rate of cell division at the meristematic apex itself in both Fhleum and Zea is very low, so low in fact that it would be difficult to quote a Cited by: 8.

    One outstanding question in biology is the problem of devel­ opment: how the genetic instructions encoded in the DNA become expressed in the morphological, physiological, and behavioral features of multicellular organisms, through an ordered sequence of events that extend from the first cell division of the zygote to the adult stage and eventual death.

Histogenesis and morphogenesis in the primary root of Zea mays by Phoon Timothy Young Download PDF EPUB FB2

Classical histology describes the histological organization in Zea mays as having a “closed organization” that differs from Arabidopsis with the development of xylem conforming to predictable rules. We speculated that root apical meristem organization in a wild subspecies of Z.

Rice roots, however, have their own characteristics including well-developed air space in the matured cortex. In addition, many examples of coordination were shown in root organo- and histogenesis as well as root by: The first morphogenetic events of lateral root primordium (LRP) formation in the Arabidopsis thaliana (L.)

In contrast with other cells generated by the root apical meristem in Arabidopsis, pericycle cells adjacent to the protoxylem poles of the vascular cylinder continue to cycle without interruption during passage through the elongation and differentiation zones.

However, only some of the dividing pericycle cells are committed to the asymmetric, formative divisions that give rise to lateral. THE ROOT SYSTEM AND ITS MOST IMPORTANT REGULATORS. Root systems show significant morphological diversity (reviewed in Hodge et al., ), which suggests their high specification and adaptation to various environmental dicots and in some monocots the root system consists of a primary root with lateral branchings developing mostly at right angles from pericycle by:   Ashby, E.

INTRODUCTION. Leaves are lateral organs that are produced from the flanks of the shoot apical meristem (SAM). Leaf development can be divided into three continuous and overlapping phases: initiation, primary morphogenesis (PM), and secondary morphogenesis (SM) or histogenesis (Poethig, ; Dengler and Tsukaya, ; Holtan and Hake, ; Barkoulas et al., ; Efroni et al., ).Cited by: A book assembling a comprehensive account of pea genome was published toward the end of the last century.

Cyclins are primary regulators of the activity of cyclin-dependent kinases, which are known to play critical roles in controlling eukaryotic cell cycle progression. While there has been extensive research on cell cycle mechanisms and cyclin function in animals and yeasts, only a small number of plant cyclins have been characterized functionally.

The developmental mechanisms of conventional bifacial leaves have been well studied in model plants including Arabidopsis (Arabidopsis thaliana) and maize (Zea mays) (Fig. 4), and those of other leaf types are being progressively elucidated in different plant species.
