Preface to The Visible Plant Cell: Biosensors and Bioreporters

The adage ‘a picture is worth a thousand words’could not be more true than in the study of the dynamics ofplant development and cell function. Over the past 20 yearsthere has been a convergence of plant molecular

The Plant Oncogene rolB Alters Binding of Auxin to Plant Cell Membranes

We measured auxin-binding capacity of the membrane preparationsfrom tobacco cells transformed by rolB as compared to untransformedcontrols. In the transformed cells, the overall auxin-bindingactivity is severalfold enhanced through an increase in a bindingactivity removable from the membranes at 0.5 M salt, while thebinding activity still attached to the membranes after saltwashes remains unchanged. Antibodies against the 22 kDa maizeauxin binding protein (ABP) depress most of the membrane-attachedbinding activity in both normal and rolB-transformed cells,while they do not affect the salt-washable binding activity.In contrast, antibodies against the RolB protein prevent completelybinding of auxin to the latter activity in both normal and transformedcells, while substantially unaffecting the membrane-associatedbinding. These results point to the presence, in untransformedmembranes, of an auxin-binding activity associated with a proteinimmunologically related to RolB. This activity is much increasedin rolB cells. In contrast, the auxin-binding protein analogousto maize ABP present in tobacco membranes does not increasein the rolB-transformed cells. (Received October 1, 1993; Accepted April 22, 1993)     

Cell polarity: PIN it down!

How do plants create and maintain cell polarity? Recent studies reveal a plant-specific mechanism, which links the static cellulose-based extracellular matrix to the dynamic localization of PIN auxin carrier proteins.     

The Darwinian Revolution,as seen in 1979 and as seen Twenty-Five Years Later in 2004

My book, The Darwinian Revolution gives an overview of the revolution as understood at the time of its writing (1979). It shows that many factors were involved, from straight science through philosophical methodology, and on to religious influences and challenges. Also of importance were social factors, not the least of which was the professionalization of science in Britain in the 19th century. Since the appearance of that book, new, significant factors have become apparent, and here I discuss some of the most important – especially the way in which evolution as an idea came into being as an epiphenomenon of the ideology of cultural progress; the (often tense) interaction between ideas of biological progress and the urge to professionalization, and of how this led to a delay in the full appreciation of what Charles Darwin had done in the Origin; and the ongoing divide between biological functionalists and biological formalists, a Kuhnian-type paradigm difference that persists across the Darwinian revolution.
