Transcomplementation, but not Physical Association of the CC-NB-ARC and LRR Domains of Tomato R Protein Mi-1.2 is Altered by Mutations in the ARC2 Subdomain

Race-specific disease resistance in plants is mediated by Resistance （R） proteins that recognize pathogen at- tack and initiate defence responses. Most R proteins contain a central NB-ARC domain and a C-terminal leucine-rich repeat （LRR） domain. We analyzed the intramolecular interaction of the LRR domain of tomato R protein Mi-1.2 with its N- terminus. We expressed the CC-NB-ARC and LRR parts in trans and analyzed functional transcomplementation and physical interactions. We show that these domains functionally transcomplement when expressed in trans. Known autoactivating LRR domain swaps were found to induce a hypersensitive response （HR） upon co-expression. Likewise, autoactivating mutants in the NB subdomain transcomplemented to induce HR. Point mutations in the ARC2 subdomain that induce strong autoactivation in the full-length Mi-1.2 protein, however, fail to induce HR in the transcomplementation assay, These data indicate distinct functions for the NB-ARC subdomains in induction of HR signalling. Furthermore, dissociation of the LRR is not required to release its negative regulation, as in all combinations of CC-NB-ARC and LRR domains tested, a physical interaction was observed.

Assessing Social Vulnerability to Flood Hazards in the Dutch Province of Zeeland

引用

International journal of Disaster Risk Science 2019年第2期10卷 233-243页

The 2007 European Union Floods Directive encouraged member nations to pursue a more integrated view of flood risks and management strategies, taking into account social vulnerabilities of residents. To date, most flood-risk analyses conducted by the Dutch government have focused on physical risk. This study utilizes fine-scale data to construct a social vulnerability index for 147 districts of the Dutch province of Zeeland, located in the Southwestern Delta and the scene of widespread devastation following the 1953 North Sea Flood. Factor analysis of 25 indicators of social vulnerability selected from related research in Europe and the United States results in seven factors explaining roughly 66% of the total variance. These factors of social vulnerability in Zeeland are urban density,low-income households, recent population change, female gender, train access, and self-employed and service-sector employment. The index was constructed using the toploading variable in each of these factors, with weights determined by the variance explained by each *** range from a low of 0.20 in Schore, municipality of Kapelle, to the highest score of 0.64 in Oudelandse Hoeve of Terneuzen. The most vulnerable districts are located in South Zeeland, with eight of the 10 found in *** majority of less vulnerable districts are located in Zeeland’s central region.
