Calendar Name: seminars Scheduled for: Friday, October 18 2013, 14:00 - 15:30 Event text: Prof Ildoo Hwang Department of Life Sciences POSTECH Biotech Center Pohang University of Science and Technology Pohang KOREA Details: �The action of cytokinin, a phytohormone, in plant immunity� ABSTRACT Cytokinins affect plant immunity to various pathogens; however, the mechanisms coupling plant-derived cytokinins to pathogen responses have been elusive. We recently revealed that plant-derived cytokinins promote resistance of a model plant Arabidopsis to a bacterial pathogen Pseudomonas syringae. Modulated cytokinin levels or signaling activity correlate with altered resistance. Cytokinin directly modulates the expression of salicylic acid (a defense-related plant hormone) or defense-related genes via cytokinin-activated transcription factors called type-B ARRs, which interact with the salicylic acid response factor TGA3 and contribute to resistance against the pathogen by potentiating salicylic acid signaling. Other than SA signaling, cytokinin affects an elicitor flagellin-induced stomata closure and FRK1 induction, implying its role for pre-invasive defense mediated via PAMP recognition. Interestingly, cytokinin also confers a priming effect, which induces a rapid and strong defense response. Taken together, our results indicate that cytokinins modulate multitude of defense signaling to augment resistance against a bacterial pathogen. I will further discuss how plant modulates a priming defense response, especially the transcriptional competence of defense-related genes.

Calendar Name: seminars Scheduled for: Monday, October 7 2013, 11:00 - 12:30 Event text: Dr Annabelle Haudry Laboratoire de Biometrie et Biologie Evolutive Universite Lyon 1 - UMR CNRS 5558 Villeurbanne cedex FRANCE Details: �Selection on noncoding DNA in the Brassicaceae � ABSTRACT Despite the central role of noncoding DNA in gene regulation and evolution, our understanding of the genomic extent and nature of selection on plant noncoding regions remains limited. Taking advantage of newly sequenced genomes in the Brassicaceae, we combined comparative genomics and population genomics approaches to analyze patterns of molecular evolution and the strength of selection of noncoding DNA. We conducted whole genome alignments of nine Brassicaceae species, including two new genome assemblies from the DOE Joint Genome Institute (Capsella rubella and Eutrema halophila) and de novo Illumina assemblies of three additional species by the VEGI project (Aethionema arabicum, Sisymbrium irio, and Leavenworthia alabamica). Using a systematic computational approach we identified over 90,000 conserved noncoding regions (CNSs) that show a degree of conservation across species similar to average coding exons and no evidence of expression or coding potential. Gene ontology analysis revealed a significant enrichment of CNSs near transcription factors and CNSs were found to be enriched in known transcription factor binding sites. These results support the potential regulatory function of CNSs. Population genomic analyses in A. thaliana and C. grandiflora showed reduced levels of diversity and excess of rare variants for CNSs compared to neutral expectation, confirming that most CNSs evolve under purifying selection. Our analysis indicates the strength of selection acting on plant noncoding regions, highlighting the likely importance of these regions for functional variation and adaptive evolution.
