Salt stress is an environmental factor that severely impairs plant growth and productivity. Salinity-induced transcript accumulation was monitored in the salt-sensitive Arabidopsis thaliana and the related salt-tolerant Lobularia maritima using cDNA-arrays with expressed sequence tags derived from a
Agricultural soil pollution by heavy metals is a severe global ecological problem. We recently showed that overexpression of LmSAP, a member of the stress-associated protein (SAP) gene family isolated from Lobularia maritima, in transgenic tobacco led to enhanced tolerance to abiotic stress. In this
Stress-associated proteins (SAPs), such as A20/AN1 zinc-finger domain-containing proteins, have emerged as a novel class of proteins involved in abiotic stress signaling, and they are important candidates for preventing the loss of yield caused by exposure to environmental stresses. In a previous
