Allelochemicals: Role en Plante Environnement Interactions
Description
During evolution, le plants developed new biosynthetic pathways to produce secondary metabolites (flavonoids, alkaloids, cyanogenic glycosides, glucosinolates, phenolics et tannins) known as allelochemicals. These provide adaptative advantages to plants pour survival against herbivores, pests (insects, nematodes, pathogens, weeds), environmental stresses et other plants. They can be considered as le chemical language de plants, which continuously changes et increases en complexity avec their evolution. Allelopathy phenomenon refers to inhibitory or stimulatory biochemical interactions between le plant-plants, plant-predators et plant-pathogens mediated by plant allelochemicals released into le environment as leachates, volatiles, root exudates et decomposition de plant residues. Le allelochemicals affects numerous biochemical reactions/metabolic processes (photosynthesis et respiration etc) en plants et such actions may be determined at molecular, structural, biochemical, physiological et ecological levels. This book aims to provide an overview de structure, origin et mode de release de plant allelochemicals et their biological roles en allelopathic interactions. Le book contains Introduction et 11 chapters. This book describes le chemical basis de allelopathic interactions at molecular levels. It will be very useful to Students et Rechercheers en Biologie, Agriculture, Organic Chimie et other Plante Sciences.
