Increasing examples of TFs that function non-cell-autonomously are being discovered and methods to assess intercellular trafficking are also addressed. A section is devoted to examining interaction with DNA, and the volume concludes with a discussion of directed evolution to generate transcription factors that can more efficiently control desired processes. Written in the highly successful Methods in Molecular Biology(TM) series format, chapters contain introductions to their respective topics, lists of the necessary materials and reagents, step-by- step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and accessible, Plant Transcription Factors: Methods and Protocols serves as an ideal guide to seasoned plant molecular biologists as well as scientists new to the field of TFs and provides many necessary methods to all scientists who are interested in exploring the functions of transcription factors.
