18066586 Lee MO, Cho K, Kim SH, Jeong SH, Kim JA, Jung YH, Shim J, Shibato J, Rakwal R, Tamogami S, Kubo A, Agrawal GK, Jwa NS: Novel rice OsSIPK is a multiple stress responsive MAPK family member showing rhythmic expression at mRNA level. Planta. 2008 Apr;227(5):981-90. Epub 2007 Dec 8.
We report isolation and transcriptional profiling of rice (Oryza sativa L.) mitogen-activated protein kinase (MAPK), OsSIPK (salicylic acid-induced protein kinase). OsSIPK gene is located on chromosome 6 most probably existing as a single copy in the rice genome, and encodes 398 amino acid polypeptide having the MAPK family signature and phosphorylation activation motif TEY. Steady state mRNA analyses of OsSIPK showed weak constitutive expression in leaves of 2-week-old rice seedlings. A time course (30-120 min) experiment using a variety of elicitors and stresses revealed that the OsSIPK mRNA is strongly induced by jasmonic acid (JA), salicylic acid (SA), ethephon, abscisic acid, cycloheximide (CHX), JA/SA + CHX, cantharidin, okadaic acid, hydrogen peroxide, chitosan, sodium chloride, and cold stress (12 degrees C), but not with wounding by cut, gaseous pollutants ozone, and sulfur dioxide, high temperature, ultraviolet C irradiation, sucrose, and drought. Its transcription was also found to be tissue-specifically regulated, and followed a rhythmic dark induction in leaves. Finally, we showed that the OsSIPK protein is localized to the nucleus. From these results, OsSIPK can be implicated in diverse stimuli-responsive signaling cascades and transcription of certain genes.
