Formation of plant resistance to pathogens involving epigenetic factors and phytohormones

The development of resistance to plant pathogens is determined by the presence genes and regulation their activity due phytohormones, nuclear pore complex, epigenetic modifications at post-transcriptional post-translational levels DNA histones, respectively. Changes in gene expression such can be inherited generations contribute selection resistant plants populations.The complex composed nucleoporins, a basket, cytoplasmic filaments able selectively transport transcription factors nucleus from cytoplasm mRNA opposite direction, affecting expression. Methylation most common well-studied among modifications. It described for histones ensures genome stability availability factors. Incorporation methyl groups amino acid residues not always factor silencing histones. number incorporated as well an they are attached crucial. Histone acetylation associated with transition transcriptional activity.The general control histone acetyltransferase TaGCN5 promote enoyl-CoA reductase allohexaploid wheat, which involved biosynthesis cuticular wax one reverse process deacetylation acts both positive regulator, through ethylene response factors, negative one, it interferes methylation acids. Jasmonic salicylic acids, along combinations mentioned mediate formation systemic acquired addition ethylene. Auxin phytohormone its ability influence structure cell wall. At same time, pathogens, effectors, inhibit plant’s immune responses, so there constant “arms race” resulting more effective means penetration protective reactions. Investigation mechanisms identifying main resistance, either sequence and/or regulating expression, great importance.
