Abstract:

Low temperature,drought and high salinity are main abiotic stresses which have adverse effects on plant growth and crop production.It is important to study the responses of plant to environmental stresses and the molecular mechanism of abiotic stress signal transduction.Recent research indicates that both ABA-dependent and ABA-independent regulatory systems are involved in stress-responsive gene expression.For several stress inducible genes,cis-acting elements in promoter regions and the corresponding trans...

Key words: abiotic stress, ABA, cis-acting element, transcription factor;
