Annual Plant Reviews, Volume 12 A fundamental feature of developmental biology is that of theestablishment of polarity. It can be described at different levels- polarity of the organism, polarity in tissue patterning and organdevelopment, and polarity of the cell. This volume provides an account of current research into themechanisms by which polarity is generated at the level of the cell,organ and organism in plants, drawing especially on recent workwith model organisms.The emphasis is on the use of the techniquesof molecular genetics to dissect molecular mechanisms. This is the first volume to bring together the diverse aspects ofpolarity in plant development. It is directed at researchers andprofessionals in plant developmental biology, cell biology andmolecular biology. Visit www.blackwellplantsci.com the plant science site fromBlackwell Publishing.

The importance of the plant growth regulator auxin for plant growth has long been recognized, even before the discovery of its chemical structures in the early 20th century. Physiological studies in the decades since have demonstrated that auxin is unidirectionally transported in plants, a process dubbed polar auxin transport. It is the polar auxin transport process that generates a local auxin concentration gradient and regulates a broad array of physiological and developmental processes. The discoveries of auxin transport carrier proteins that mediate auxin influx into and efflux out of transport-competent cells and auxin receptor proteins for auxin signaling in the last few decades represent significant milestones in auxin research and open up opportunities to probe the cellular and molecular processes that regulate auxin transport and integrate environmental cues with signaling processes. Remarkably, components of the polar auxin transport machinery are present in both lower plants such as mosses and higher plants including monocots and eudicots, illustrating the key role of polar auxin transport in plant evolution. This book highlights topics ranging from physiological and genetic studies of polar auxin transport in plant development, to growth responses to the environment and plant-microbe interactions, to hormonal cross-talks with various cellular and molecular regulatory processes essential for polar auxin transport.

Tells about a variety of polar plants, how they are used, why they are in danger, and how they are being protected.
