Mitogen-activated protein kinases (MAPKs) are versatile phosphorylating enzymes which regulate multiple proteins involved in gene expression, cell architecture, plant development and reaction to diverse abiotic and biotic factors. The main aim of Plant MAP Kinases: Methods and Protocols is to provide established and new MAPK protocols adapted to the challenges posed by working with plants. The book contains 19 chapters which encompass a wide array of methods progressively scaling from the single gene, protein or cell level to large-scale arrays of proteomic, phosphoproteomic and interactomic data in order to uncover previously unidentified plant MAPK signaling pathways and to tackle with the challenging task of substrate identification. Techniques for MAPK sequence analysis and subcellular localization helping to identify their substrates and subcellular compartmentalization are also provided. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols and key tips on troubleshooting and avoiding known pitfalls.

Authoritative and practical, Plant MAP Kinases: Methods and Protocols represents a collection of useful plant MAPK protocols written by experts in the field for researchers and students.

Proteomics is the large-scale functional analysis of proteins extracted from intact organisms, tissues, individual cells, or cell compartments, at defined timepoints during development or under specific conditions.

Plant Proteomics highlights the rapid progress in this field in plants, with emphasis on recent work in model plant species, subcellular organelles, and specific aspects of the plant life cycle such as signalling, reproduction and stress physiology. Diverse integrated approaches, including advanced proteomic techniques combined with functional genomics, bioinformatics, metabolomics and molecular cell biology, are presented in several chapters, making this book a valuable resource for a broad spectrum of readers ranging from teachers and advanced students to researchers.

Endocytosis is a fundamental cellular process by means of which cells internalize extracellular and plasma membrane cargos for recycling or degradation. It is important for the establishment and maintenance of cell polarity, subcellular signaling and uptake of nutrients into specialized cells, but also for plant cell interactions with pathogenic and symbiotic microbes. Endocytosis starts by vesicle formation at the plasma membrane and progresses through early and late endosomal compartments. In these endosomes cargo is sorted and it is either recycled back to the plasma membrane, or degraded in the lytic vacuole. This book presents an overview of our current knowledge of endocytosis in plants with a main focus on the key molecules undergoing and regulating endocytosis. It also provides up to date methodological approaches as well as principles of protein, structural lipid, sugar and microbe internalization in plant cells. The individual chapters describe clathrin-mediated and fluid-phase endocytosis, as well as flotillin-mediated endocytosis and internalization of microbes. The book was written for a broad spectrum of readers including students, teachers and researchers.
