Towards revealing the functions of all genes in plants

Trends Plant Sci. 2014 Apr;19(4):212-21. doi: 10.1016/j.tplants.2013.10.006. Epub 2013 Nov 11.


The great recent progress made in identifying the molecular parts lists of organisms revealed the paucity of our understanding of what most of the parts do. In this review, we introduce computational and statistical approaches and omics data used for inferring gene function in plants, with an emphasis on network-based inference. We also discuss caveats associated with network-based function predictions such as performance assessment, annotation propagation, the guilt-by-association concept, and the meaning of hubs. Finally, we note the current limitations and possible future directions such as the need for gold standard data from several species, unified access to data and tools, quantitative comparison of data and tool quality, and high-throughput experimental validation platforms for systematic gene function elucidation in plants.

Keywords: big data; co-expression; co-function; function prediction; networks; omics.
