19463922 Chung E, Cho CW, Yun BH, Choi HK, So HA, Lee SW, Lee JH: Molecular cloning and characterization of the soybean DEAD-box RNA helicase gene induced by low temperature and high salinity stress. Gene. 2009 Aug 15;443(1-2):91-9. Epub 2009 May 20.

Northern blot analysis demonstrated that the RNA expression of the GmRH was induced during low temperature or high salinity stress, but not by the exogenous application of abscisic acid or drought stress.

This gene is expressed in response to NaCl and not polyethlene glycol (PEG) nor abscisic acid, and its expression increases with time.

Germination of mutant seed was hyposensitive to the phytohormone abscisic acid (ABA), but mutants showed up-regulated expression of genes encoding ABA-dependent stress-responsive transcriptional activators and their downstream targets.

This chapter first describes the adverse effect of salinity stress and general pathway for the plant stress response, followed by roles of various ion pumps, calcium, SOS pathways, ABA, transcription factors, mitogen-activated protein kinases, glycine betaine, proline, reactive oxygen species, and DEAD-box helicases in salinity stress tolerance.

We have isolated a DEAD-box-containing cDNA sequence from Medicago sativa (alfalfa) that is a homolog of the pea DNA helicase 45 (PDH45) and named it M. sativa helicase 1 (MH1).
Furthermore, real-time PCR analysis revealed that mannitol, NaCl, methyl viologen and abscisic acid induced the expression of MH1.
