Bacterial wilt caused by Ralstonia solanacearum is one of the most destructive bacterial plant diseases. Although many molecular determinants involved in R. adaptation to hosts and pathogenesis have been described, host components required for disease establishment remain poorly characterized. Phenotypical analysis Arabidopsis mutants leucine-rich repeat (LRR)-receptor-like proteins revealed that mutations CLAVATA1 (CLV1) CLAVATA2 (CLV2) genes confer enhanced resistance wilt. We further...
• Means to control bacterial wilt caused by the phytopathogenic root bacteria Ralstonia solanacearum are limited. Mutants in a large cluster of genes (hrp) involved pathogenicity R. were successfully used previous study as endophytic biocontrol agents challenge inoculation experiments on tomato. However, molecular mechanisms controlling this resistance remained unknown. We developed protection assay using Arabidopsis thaliana model plant and analyzed events underlying biological genetic,...
One of the main outcomes quantitative genetics approaches to natural variation is reveal genetic architecture underlying phenotypic space. Complex architectures are described as including numerous loci (or alleles) with small-effect and/or low-frequency in populations, interactions background, environment or age. Linkage association mapping strategies will be more less sensitive this complexity, so that we still have an unclear picture its extent. By combining high-throughput phenotyping...
Verticillium spp. are destructive soilborne fungal pathogens that cause vascular wilt diseases in a wide range of plant species. wilts particularly notorious, and genetic resistance crop plants is the most favorable means disease control. In gain-of-function screen using an activation-tagged Arabidopsis mutant collection, we identified four mutants, A1 to A4, which displayed enhanced toward species dahliae, V. albo-atrum longisporum but not Fusarium oxysporum f. sp. raphani. Further testing...
Abstract Investigating the evolution of complex phenotypes and underlying molecular bases their variation is critical to understand how organisms adapt environment. Applying classical quantitative genetics on a segregating population derived from Can-0xCol-0 cross, we identify MADS-box transcription factor FLOWERING LOCUS M (FLM) as player phenotypic in plant growth color. We show that allelic at FLM modulates strategy along leaf economics spectrum, trade-off between resource acquisition...
Soil-borne vascular wilt diseases caused by Verticillium spp. are among the most destructive worldwide in a wide range of plant species. The effective means controlling is use genetic resistance. We have previously reported identification four activation-tagged Arabidopsis mutants which showed enhanced resistance to wilt. Among these, one mutant also Ralstonia solanacearum, bacterial pathogen. Cloning activation tag revealed an insertion upstream gene At3g13437, we designated as EWR1 (for...
The mechanisms of reproductive isolation that cause phenotypic diversification and eventually speciation are a major topic evolutionary research. Hybrid necrosis is post-zygotic mechanism in which cell death develops the absence pathogens. It often due to incompatibility between proteins from two parents. Here we describe unique case hybrid an loci on chromosomes 2 7 pollinator-isolated Petunia species. Typical immune responses as well endoplasmic reticulum stress induced necrotic line....
Summary Adaptation to different pollinators is an important driver of speciation in the angiosperms. Genetic approaches such as QTL mapping have been successfully used identify underlying genes. However, these methods are often limited by widespread suppression recombination due divergence between species. While mutations that caused interspecific differences floral color and scent elucidated a variety plant genera, genes responsible for morphological remain mostly unknown. Differences organ...
Summary Proline‐rich extensin‐like receptor kinases (PERKs) are an important class of receptor‐like (RLKs) containing extracellular proline‐rich domain. While they thought to be putative sensors the cell wall integrity, there very few reports on their biological functions in plant, as compared with other RLKs. Several studies support a role for PERKs plant growth and development, but effect composition regulate expansion is still lacking. Gene expression data suggest that may intervene...
ABSTRACT Investigating the evolution of complex phenotypes and underlying molecular bases their variation is critical to understand how organisms adapt environment. We used leaf growth as a model trait it highly integrative internal external cues relies on functions at different levels plant organization. Applying classical quantitative genetics recombinant inbred line population derived from Can-0 x Col-0 cross, we identified MADS-box transcription factor FLOWERING LOCUS M ( FLM ) player...
