“…In other situations, detached stem cuttings form adventitious roots following a period of callus induction and reorganization (e.g. Bacon et al ., 1994; Hamann, 1998). Therefore, it appears that there are at least two pathways by which adventitious roots form, or can be induced to form: by direct organogenesis from established cell types such as the cambium; or from callus tissue following mechanical damage, such as occurs when cuttings are taken.…”

Contents Introduction 11 Cellular origins of root meristems 12 Regulation of cell identity in the root 13 Hormonal signals in root development 14 The genetics of root pattern 19 Root architecture: regulation of de novo root formation 24 Conclusions 33 References 33 Summary The plant root plays a range of roles, such as in the acquisition of water and nutrients, the provision of structural support and as the site of interactions with mycorrhizae, nitrogen fixing organisms (in certain taxa) and diverse pests and pathogens. It also provides an important experimental system to study different aspects of plant organogenesis, including the regulation of pattern formation, cell division, intercellular signalling and cell differentiation. With the completion of the Arabidopsis sequencing programme, and the availability of very large collections of Arabidopsis mutants, it is feasible rapidly to gain new information on the control of each of these aspects of root development. Drawing principally from experimental work using this model organism, which has proved extremely amenable to genetic and physiological analysis, we aim to bring together recent advances in knowledge and understanding of the molecular basis of root organogenesis, from origins in embryogenesis to postgermination architecture.

Sphingolipid-mediated Signalling in Plants,

A plethora of biological effects, ranging from cellular survival to apoptosis, has been assigned to sphingolipids and, in particular, to the sphingolipid metabolites ceramide, sphingosine and sphingosine-1-phosphate. One aspect of sphingolipid biology that is currently attracting a great deal of interest in animals and yeast is their role in cell signalling. In contrast, much less is known about sphingolipids in plants, although available information suggests that these compounds may also fulfil important signalling roles. There are suggestions that sphingolipid metabolites may be involved in diverse processes including pathogenesis, membrane stability and the response to drought. Here, we review current information on the role of sphingolipid metabolites and highlight their emerging roles in plant signalling.
