This second edition compiles state-of-art protocols to study the molecular mechanisms that determine proteome composition and contribute to maintaining protein homeostasis. Chapters describe methods that range from the in vitro analysis of enzyme cascades to real-time in vivo studies. Written in the 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 protocols, and notes on troubleshooting and avoiding known pitfalls.Authoritative and cutting-edge, Plant Proteostasis: Methods and Protocols, Second Edition aims to be a useful practical guide to researches to help further their study in this field.

Includes cutting-edge methods and protocols
