Identification of epigenetically regulated genes involved in plant-virus interaction and their role in virus-triggered induced resistance [Elektronski vir]Corrêa, Régis L. ...Background: Plant responses to a wide range of stresses are known to be regulated by epigenetic mechanisms. Path-ogen-related investigations, particularly against RNA viruses, are however scarce. It ... has been demonstrated that Arabi-dopsis thaliana plants defective in some members of the RNA-directed DNA methylation (RdDM) or histone modi-fication pathways presented differential susceptibility to the turnip mosaic virus. In order to identify genes directly targeted by the RdDM-related RNA Polymerase V (POLV ) complex and the histone demethylase protein JUMONJI14 (JMJ14) during infection, the transcriptomes of infected mutant and control plants were obtained and integrated with available chromatin occupancy data for various epigenetic proteins and marks. Results: A comprehensive list of virus-responsive gene candidates to be regulated by the two proteins was obtained. Twelve genes were selected for further characterization, confirming their dynamic regulation during the course of infection. Several epigenetic marks on their promoter sequences were found using in silico data, raising confidence that the identified genes are actually regulated by epigenetic mechanisms. The altered expression of six of these genes in mutants of the methyltransferase gene CURLY LEAF and the histone deacetylase gene HISTONE DEACETYLASE 19 suggests that some virus-responsive genes may be regulated by multiple coordinated epigenetic complexes. A temporally separated multiple plant virus infection experiment in which plants were transiently infected with one virus and then infected by a second one was designed to investigate the possible roles of the identified POLV- and JMJ14-regulated genes in wild-type (WT ) plants. Plants that had previously been stimulated with viruses were found to be more resistant to subsequent virus challenge than control plants. Several POLV- and JMJ14-regulated genes were found to be regulated in virus induced resistance in WT plants, with some of them poisoned to be expressed in early infection stages. Conclusions: A set of confident candidate genes directly regulated by the POLV and JMJ14 proteins during virus infection was identified, with indications that some of them may be regulated by multiple epigenetic modules. A sub-set of these genes may also play a role in the tolerance of WT plants to repeated, intermittent virus infections.Keywords Biotic stress, Defense priming, Epigenetics, Histone modifications, Induced resistance, Potyvirus, RNA-directed DNA methylation.Source: BMC plant biology [Elektronski vir]. - ISSN 1471-2229 (Vol. 24, art. no. 172, 2024, str. 1-20)Type of material - e-article ; adult, seriousPublish date - 2024Language - englishCOBISS.SI-ID - 189559299
