This detailed volume explores barley as both a crop and a model, with practical techniques such as crossing barley, a range of tissue culture methods, the preparation of barley tissues for different forms of microscopy, and the assessment of sensitivity to abiotic stresses. Efficient protocols are provided for transformation, TILLING, virus-induced gene silencing and genome editing. There is also particular emphasis on a range of protocols for genotyping and for the analysis of gene expression. Written for the highly successful Methods in Molecular Biology series, chapters include introductions on 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.
