Overexpression of Stress-Associated Protein from Rice Increases Salt Tolerance in ArabidopsisJuly 29, 2015
The stress-associated protein (SAP) family has been found to provide salinity stress tolerance in plants. Zamri Zainal of the Universiti Kebangsaan Malaysia and a team of researchers studied SAP MR219, a SAP member induced by salinity stresses.
Analysis of the SAP MR219 cDNA clone isolated from Oryza sativa var. MR219 revealed that its gene product performs its functions via protein–protein interactions. The SAP MR219 gene was then introduced and overexpressed in Arabidopsis thaliana, creating transgenic Arabidopsis lines which were evaluated under salinity stress. At 250 mM NaCl, the transgenic lines had almost 50% germination rate whereas the wild-type plants did not grow at all. These results indicate that SAP MR219 may play a significant role in plant response to salt stress.
