Cell signaling under salt, water and cold stresses

Curr Opin Plant Biol. 2001 Oct;4(5):401-6. doi: 10.1016/s1369-5266(00)00192-8.


Forward genetics and biochemical approaches to studying plant responses to salt, water and cold stresses began to bear fruit recently. Analysis of salt overly sensitive (sos) Arabidopsis mutants revealed a novel calcium-regulated protein kinase pathway for response to the ionic aspect of salt stress. In-gel kinase assays identified several SOS-independent protein kinases that are either activated specifically by osmotic stress or by multiple abiotic and biotic stresses. Molecular analysis revealed a transcriptional cascade in cold-regulated gene expression.
