The book provides an up-to-date synopsis of the flagellar apparatus/cytoskeleton of protists. The reader will find new information on all aspects of the cell and molecular biology related to the topic. The book will examine the flagellar apparatus/cytoskeleton using topical and systematic approaches. The topical chapters flagellar membrane and flagellar surface, axonemal structure, molecular function and behavioral response, molecular evolution of tubulin genes, basal apparatus proteins, genetic analysis of basal body function and formation, flagellar apparatus development during the cell cycle, flagellar motility patterns. The systematic chapters archezoan flagellate, auglenoids and kinetoplastids, dinoflagellates, ciliates, chromophytes, zoosporic fungi. In addition the book contains an introductory multi-author chapter on terminology and nomenclature of the cytoskeleton of flagellate protists. The concept of examining protists, and specifically the flagellar apparatus/cytoskeleton, from both a cell/molecular viewpoint and a systematic viewpoint is novel. Together these viewpoints show the unique and widespread occurence of new information and provide a better understanding of the evolutionary relationships among the diverse organisms placed in the Protists. Readers will find new and exciting information in one authoritative volume, providing a single text that addresses an important topic in contemporary protistology.
