![]() The same results were observed with drought and wound treatments. Moreover, the transcription of TaRar1 was induced by methyl jasmonate, ethylene, and abscisic acid hormones. Characterization of TaRar1 expression revealed that the expression was tissue-specific and up-regulated in wheat during stripe rust infection. The three TaRAR1 proteins all contain two conserved cysteine-and histidine-rich domains (CHORD-I and -II) shared by known RAR1-like proteins. tritici ( Pst), we identified and cloned three wheat homeologous genes highly similar to the barley HvRar1, designated as TaRar1-2A, TaRar1-2B, and TaRar1-2D. To study the function of TaRAR1 involvement in wheat ( Triticum aestivum L.) defense against the infection of stripe rust pathogen Puccinia striiformis f. RAR1 is a eukaryotic zinc-binding protein first identified as required for race-specific resistance to powdery mildew in barley. 4China–Australia Joint Research Centre for Abiotic and Biotic Stress Management, Northwest A&F University, Yangling, China.3Department of Plant Sciences and Plant Pathology, Montana State University, Bozeman, MT, USA.2State Key Laboratory of Crop Stress Biology for Arid Areas, College of Plant Protection, Northwest A&F University, Yangling, China.1State Key Laboratory of Crop Stress Biology for Arid Areas, College of Life Sciences, Northwest A&F University, Yangling, China.Xiaojing Wang 1, Yaru Wang 1, Peng Liu 2, Yan Ding 1, Xiaoqian Mu 1, Xiping Liu 1, Xiaojie Wang 2, Mengxin Zhao 2, Baoyu Huai 1, Li Huang 3* and Zhensheng Kang 2,4*
