The proteome comprises all protein species resulting from geneexpression in a cell, organelle, tissue or organism. By definition,proteomics aims to identify and characterise the expressionpattern, cellular location, activity, regulation,post-translational modifications, molecular interactions, threedimensional structures and functions of each protein in abiological system.
In plant science, the number of proteome studies is rapidlyexpanding after the completion of the Arabidopsis thalianagenome sequence, and proteome analyses of other important oremerging model systems and crop plants are in progress or are beinginitiated. Proteome analysis in plants is subject to the sameobstacles and limitations as in other organisms, but the nature ofplant tissues, with their rigid cell walls and complex variety ofsecondary metabolites, means that extra challenges are involvedthat may not be faced when analysing other organisms.
This volume aims to highlight the ways in which proteomeanalysis has been used to probe the complexities of plantbiochemistry and physiology. It is aimed at researchers in plantbiochemistry, genomics, transcriptomics and metabolomics who wishto gain an up-to-date insight into plant proteomes, the informationplant proteomics can yield and the directions plant proteomeresearch is taking.
