In-Depth Information
Proteomics has clearly brought important discoveries
for our innate understanding of the molecular mecha-
nisms and complex signalling and metabolic networks
in leguminous crops under salt stress. By integrated
analysis of current proteomics results available for five
plant species ( A. hypogea, G. max, L. sativus, L. luteus and
P. sativum ) we found 452 protein identities representing
255 unique proteins (UPs). Most of the proteomic
studies have reported the abundant salt-responsive pro-
teins rather than the low-abundance proteins, including
salt-responsive transcription factors, protein kinases and
membrane/vesicle transport proteins. Clearly pro-
teomics still has much to fulfil of its presumed potential
in this area. Integration of 'omics' tools such as tran-
scriptomics, proteomics and metabolomics will give us a
more holistic view of the molecular mechanisms under-
lying salt stress responses and tolerance. This can then
be used to predict and validate how diverse components
generate responses and control different pathways
toward the ultimate goal of improving salt tolerance in
leguminous crops for enhanced productivity.
