سالیسیلیک اسید نقش مهمی در دفاع گیاهان علیه ویروس ها ایفا می کند. مقاومت اکتسابی سیستمیک القا شده توسط سالیسیلیک اسید باعث مقاومت طولانی مدت به طیف وسیعی از بیمارگرها از جمله ویروس ها می شود. در مورد ویروس ها، سالیسیلیک اسید می تواند از سه مرحله اساسی در چرخه بیماریزایی ویروس شامل همانندسازی، حرکت سلول به سلول و حرکت در مسافت طولانی جلوگیری کند. فاکتور های رونویسی خانواده های tga ، myb و wrky د...
Parsley WRKY proteins comprise a family of plant-specific zinc-finger-type factors implicated in the regulation of genes associated with pathogen defence. In vitro, these proteins bind specifically to functionally defined TGAC-containing W box promoter elements within the Pathogenesis-Related Class10 (PR-10) genes. Here we present in vivo data demonstrating that WRKY1 is a transcriptional activ...
WRKY18, WRKY40 and WRKY60 are members of the WRKY transcription factor family and function as transcriptional regulators in ABA signal transduction in Arabidopsis thaliana. Here we show that WRKY18 and WRKY40, but not WRKY60, co-localise with PIF3, PIF4 and PHYB to Phytochrome B-containing nuclear bodies (PNBs). Localisation to the PNBs is phosphorylation-dependent and is inhibited by the gener...
bZIPs and WRKYs are two important plant transcription factor (TF) families regulating diverse developmental and stress-related processes. Since a partial overlap in these biological processes is obvious, it can be speculated that they fulfill non-redundant functions in a complex regulatory network. Here, we focus on the regulatory mechanisms that are so far described for bZIPs and WRKYs. bZIP f...
Expression of OsWRKY71, a rice WRKY gene, was induced by biotic elicitors and pathogen infection. It was also found that OsWRKY71 has features characteristic of a transcriptional repressor. Microarray analysis revealed that several elicitor-induced defense-related genes were upregulated in rice cells overexpressing OsWRKY71. These results indicate that the activation of defense-related genes by...
Virulent Agrobacterium tumefaciens strains integrate their T-DNA into the plant genome where the encoded agrobacterial oncogenes are expressed and cause crown gall disease. Essential for crown gall development are IaaH (indole-3-acetamide hydrolase), IaaM (tryptophan monooxygenase) and Ipt (isopentenyl transferase), which encode enzymes for the biosynthesis of auxin (IaaH, IaaM) and cytokinin (...
WRKY transcription factors are involved in multiple aspects of plant growth, development and responses to biotic stresses. Although they have been found to play roles in regulating plant responses to environmental stresses, these roles still need to be explored, especially those pertaining to crops. Durum wheat is the second most widely produced cereal in the world. Complex, large and unsequenc...
