The book provides a current review of the field of phyllotaxis from a variety of perspectives, that is, morphological, developmental, biochemical, molecular genetics, biophysical, and evolutionary.This unique book covers phyllotactic processes from the level of genes involved in the establishment of patterns to modeling the emergence of those patterns in space and time. The models in question (deterministic or stochastic) touch on various fields, including geometry, biochemistry, and biophysics.Not only providing a recent review but also current critique and analysis of the discipline, the book will appeal to a variety of individuals involved in developmental modeling as well as pattern initiation and formation. The text is highly illustrated with excellent pictures representing recent developments in the field.A biological context or perspective to models and ideas is explored in the book. Terminology specific to the discipline is defined and updated as well.

Symmetry and the causes of shifts in different types of symmetries in flowers follow specific patterns that are ruled by developmental and genetic factors. Using a unified system of phyllotaxic equations, we have modeled the molecular mechanisms and pressure forces that act in inflorescence and floral meristems, giving flowers their organ arrangement. In this book, we state general physical principles, whereby the symmetry of the perianth is derived from the symmetry of certain TCP gene expression. Thus, we define the interplay between the expression of CYC2-like genes and the phyllotactic mechanisms. This new evo-devo approach is applied to major groups of angiosperms with predominantly actinomorphic flowers (in which rare zygomorphy is positional) and groups with mainly bilaterally symmetrical flowers (in which zygomorphy is constitutional). It has thus allowed us to revisit the contributions of the great floral morphologists of the 20th and early 21st centuries.

The equations of phyllotaxis were discovered by Douady and Couder: these describe the inhibition "force" generated by an incipient primordium, preventing the initiation of other primordia in its vicinity: the method that was lacking was to take into account the distance of primordia to the meristem apex over the course of its development. With these parameters, our model integrates both biochemical "forces" (inhibition due to auxin) and mechanical forces (contact pressure). This powerful tool allows us to revisit many important notions of plant biology. For example, we model auxin concentrations at the plant apex, as well as the development of vegetative and reproductive meristems. We also explain why the whorls of monocots are trimerous and those of plants with quincuncial perianths are pentamerous. We design a geometric method for reconstructing inflorescences from their building blocks, i.e. floral meristems. We also show that phyllotaxic spirals are only the application of a general property of symmetry, the advantages of which have been exploited by natural selection.

Here are the recent investigations of several distinguished biologists originally presented at the Fourteenth Symposium of the Society for the Study of Development and Growth. New tools and methods are used as they examine a wide range of cellular activities at various levels of plant and animal life. Originally published in 1956. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Plant Physiology, Volume VA: Analysis of Growth: Behavior of Plants and their Organs describes the main events of growth as seen through the behavior of plants and their organs at an organismal level. This book discusses the quantitative interpretation of growth; the effects of environmental factors; the treatment of tropism; and the effects of many exogenous growth-regulating compounds. Organized into five chapters, the book initially describes mathematically the plant growth mechanisms as they relate to the factors that determine morphogenesis. The text also discusses methods for assessing the effects of external conditions and of age on certain important physiological aspects of plant growth. The subsequent chapter deals with phyllotaxis as a selected aspect of the interpretation of growth and form. The third chapter describes various phototropically and geotropically sensitive systems impinge upon on plant growth. This chapter also covers some reversible nastic movements of organs and the tactic movements of free swimming cells. The next chapter deals with relations between the chemical structure of synthetic compounds and their biological action. The last chapter focuses on the modulation of growth and development by features of the environment and also upon experimental manipulation and under controlled conditions of growth. This volume is an invaluable resource for plant biologists, physiologists, and researchers.
