High-resolution molecular networks from novel 'omics' approaches elucidate survival strategies in organsisms from land to sea
Molecular networks drive nearly all cellular processes. With the advent of omics technologies involving next-generation sequencing and mass spectrometry, we have started to uncover highly complex gene, protein, and biochemical networks that underlie survival mechanisms like growth and stress toleran...

Molecular networks drive nearly all cellular processes. With the advent of omics technologies involving next-generation sequencing and mass spectrometry, we have started to uncover highly complex gene, protein, and biochemical networks that underlie survival mechanisms like growth and stress tolerance.However, the study of cell wide of protein-protein interactions that importantly link genomic, transcriptomic, and proteomic data to cellular activity has been hindered by technical limitations, and the need to survey and track billions of possible combinatorial protein interactions. Moreover, many omics technologies have not yet been developed or applied to non-model organisms, particularly to ecologically and economically important species that may be negatively impacted by climate change.
