“…Quantitative analyses using high performance liquid chromatography and multivariate analysis of the resulting data showed that the profiles of phenolic metabolites clearly responded to selection. The results indicate (Sanlaville et al, 1988a) that analysis of phenolic profiles "".could alone be practically equivalent to use of the large sum of morphological, physiological and agronomic characters on which recognition of lines is usually based." A recent study of genetic relationships among domesticated and wild sunflowers based on randomly amplified polymorphic DNA (RAPD) loci is available (Arias and Rieseberg, 1995).…”

This book is dedicated to:Arthur Cronquist Outstanding plant systematist and major contributor to understanding taxonomic relationships within Asteraceae and Ralph E. Alston (1925Alston ( -1967) Visionary natural products chemist and geneticist who pioneered the use of chemical data in studies of plant systematics and evolution PrefaceCertainly many of the readers of this book will remember the early developments of chemosystematics in the late 1950s. We ourselves remember the excitement of these new data bearing on plant interrelationships. The hopes were high, the techniques were rapidly evolving, the quantities of data were large, and young workers were eagerly enthusiastic. Some even went so far as to predict that chemical data would soon replace morphological information as the basis for plant classification. These overly zealous predictions did not materialize, of course, as the history of plant systematics has amply shown during the past two centuries. If there is any distinct characteristic of systematics it is synthesis, as Lincoln Constance (1964) called it, the "unending synthesis." New tools generate new data and provide insights on additional dimensions of plant relationships. This will never change-we will continue to discover new tools and new data in the years ahead, and they will continue to be incorporated into the predictive general reference system of classification.The earlier efforts in chemosystematics focused on secondary plant products: alkaloids, betacyanins, carbohydrates, cyanogenic glycosides, glucosinolates, lipids, terpenoids, and especialiy flavonoids. The latter were particularly well suited for chemosystematic investigation for several reasons: ease of isolation and characterization, small amounts of plant material needed for analysis, stability of compounds especially through routine preparation of herbarium specimens, and low cost to obtain useful information. As a result of these considerable advantages, literally thousands of studies on use of flavonoids in plant systematics have been published. Although now with the present zest for macromolecular data from DNA restriction sites and sequences, there are fewer workers and laboratories dedicated to flavonoid chemosystematic studies; twenty years ago they were the new currency of exciting data in plant systematics.Because of many workers historically interested in the sunflower family, Asteraceae (or Compositae), in part due to its large size (approximately 23,000 species;Bremer, 1994), and because hundreds of flavonoid compounds were discovered in this family, many chemosystematic investigations have been completed on various taxa. Many studies came from the laboratories of R. A. Alston, B. L. Turner, and T. J. Mabry in the Department of Botany ...

Physiological and ecological constraints play key roles in the evolution of plant growth patterns, especially in relation to defenses against herbivores. Phenotypic and life history theories are unified within the growth-differentiation balance (GDB) framework, forming an integrated system of theories explaining and predicting patterns of plant defense and competitive interactions in ecological and evolutionary time. Plant activity at the cellular level can be classified as growth (cell division and enlargement) of differentiation (chemical and morphological changes leading to cell maturation and specialization). The GDB hypothesis of plant defense is premised upon a physiological trade-off between growth and differentiation processes. The trade-off between growth and defense exists because secondary metabolism and structural reinforcement are physiologically constrained in dividing and enlarging cells, and because they divert resources from the production of new leaf area. Hence the dilemma of plants: They must grow fast enough to compete, yet maintain the defenses necessary to survive in the presence of pathogens and herbivores. The physiological trade-off between growth and differentiation processes interacts with herbivory and plant-plant competition to manifest itself as a genetic trade-off between growth and defense in the evolution of plant life history strategies. Evolutionary theories of plant defense are reviewed. We also extend a standard growth rate model by separating its ecological and evolutionary components, andformalizing the role of competition in the evolution of plant defense. We conclude with a conceptual model of the evolution of plant defense in which plant physiological trade-offs interact with the abiotic environment, competition and herbivory. theory ofplant defense has not kept pace. The complexity of the subject has hindered the development of a synthetic framework, because any comprehensive treatment of plant defense theory must transcend both the disciplines and the levels of biological organiza
