Volume Two focuses on experimental approaches for studies on gene expression, gene product analysis, with the final section devoted to emerging technologies. Topics covered include a range of techniques for transcript analysis, including In situ Hybridization and DNA microarrays. DNA-proteininteraction methods are also covered in detail. Inducible gene expression in plants as well as expression and analysis of recombinant proteins, and analysis of protein import into chloroplasts are covered as well as techniques for fractionation of plant tissue for biochemical analyses and the studyof protein-protein interactions with the yeast two-hybrid system. A range of approaches for using antibodies as tools are also described including the use of antibody phage display libraries. The final section on emerging technologies describes methodologies for calcium imaging and for the spatialand temporal analysis of reporter genes such as luciferase and green fluorescent protein. The final area covers a range of experimental procedures for moss, which is emerging as a new model organism.
