摘要: The cytokinin response factor 5 (CRF5) belongs to a family of plant-specific APETALA2 (AP2)/ previously identified as mediator signaling, has been suggested increase pathogen resistance in this study. Endogenous CRF5 transcripts are expressed all tissues, including the seedlings, leaf, stem, flower, silique and root, were found be induced at 1 h after infection with bacterial pathogen, Pseudomonas syringae pv. tomato DC3000 (Pst DC3000). results yeast one-hybrid assay revealed that an acidic region CRF5, C-terminal 28 amino acids, functions transcriptional activator. Overexpression transgenic Arabidopsis increases concomitantly activates expression large number GCC-box pathogenesis-related genes. These indicate may involved disease transcription activator, thus providing mechanistic link between plant signaling.
