Challenges in proteome analyses of tropical plants

genome sequencing of various organisms allow global analysis of gene expression, providing numerous clues on the biological function and involvement in the biological processes studied. proteomics is a branch of molecular biology and biotechnology that has undergone considerable development in the post-genomic era. despite the recent significant advancements in proteomics techniques, still there is much to be improved. due to peculiarities to the plant kingdom, proteomics approaches require adaptations, so as to improve efficiency and accuracy of results in plants. data generated by proteomics can substantially contribute to the understanding and monitoring of plant physiological events and development of biotechnological strategies. especially for tropical species, challenges are even greater, in the light of the abundance of secondary metabolites, as well as of the lack of complete genome sequences. this review discusses current topics in proteomics concerning challenges and perspectives, with emphasis on the proteomics of tropical plant species.
