Abstract
Mitogen-activated protein kinases(MAPKs) play an important role in mediating the transduction of signals that are initiated by development cues and environmental factors in plants.In this study,an expressed sequence tag(EST) sharing high similarity to MAPK7-1,a MAPK gene characterized in Brachypodium,was identified in a wheat(‘ Shixin 828 ’) root subtractive suppression hybridization cDNA library.The gene corresponding to this EST was further obtained and denoted as TaMAPK7-1.The full-length cDNA of TaMAPK7-1 is 1 611 bp long,encoding a 369-aapolypeptide.A conserved motif acting as the symbol of MAPK referred to TEY is located at TaMAPK7-1,suggesting that this wheat gene has a potential function in responding distinct upstream signalings.Under low-Pi and high-salinity stresses,the TaMAPK7-1 expression levels in the wheat roots and leaves were both up-regulated compared with those before the treatments.No variations on the TaMAPK7-1 expression levels in the roots and leaves were found after the treatments of low-N and drought compared with those before the treatments.Therefore,TaMAPK7-1is responding to stresses of low-Pi and high-salinity,and is involved in mediating the transduction of signals that are initiated by aforementioned stresses.TaMAPK7-1 has a potential role in improving the plant tolerance to low-Pi and high-salinity in wheat.
