The book deals with one type of molecular markers, Cleaved Amplified Polymorphic Sequences (CAPS). This is based on PCR and polymorphism of recognition sites for restriction enzymes. The chapters are written by specialists and cover different ranges of plants: from model Arabidopsis and ferns to more important crops such as oil-crops, peas, tomato, tobacco, grasses, barley and wheat. Separate chapters discuss more exotic ramie plants; wild emmer wheat and micro-rhyzosphere in plants; but all the chapters are combined together in one book with the same topic: CAPS markers development and applications. A reader can find answers to questions such as: how can CAPS markers be easily developed for their research and how can they be applied to a wide range of plants? This book will respond to the quickly growing interests of scientists and students working with molecular markers for genetic, physiological and molecular-biological researches.
