This volume provides protocols that revolve around three pillars of progress in the plant genomics field: genotypes, phenotypes, and the molecular processes in between. Chapters in Plant Genomics: Methods and Protocols are not restricted to the predominant model species Arabidopsis thaliana, hoping to encourage and facilitate other researchers to expand their research to other species. 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 tips on troubleshooting and avoiding known pitfalls.
