High-throughput plant functional genomics utilizes new technologies for gene analysis. Integrating transcriptomics, proteomics, metabolomics, and phenomics is crucial for assigning functions to unknown plant genes.

Area of Science:

  • Plant biology
  • Genomics
  • Molecular biology

Background:

  • Complete genome information for key plant species like Arabidopsis thaliana and rice is now available.
  • Functional genome analysis in plants is advancing rapidly due to high-throughput technologies.
  • Novel, fast, and multiparallel approaches are being developed for large-scale gene analysis.

Purpose of the Study:

  • To review current technical developments in plant functional genomics.
  • To highlight the impact of these technologies on assigning functions to unknown genes.
  • To introduce Physcomitrella as a new model system for gene function analysis.

Main Methods:

  • Transcriptomics: analysis of gene expression.
  • Proteomics: analysis of proteins.
