dc.description.abstract | We provide evidence that alterations in DNA methylation patterns contribute to the
regulation of stress-responsive gene expression for an intergenerational resistance of
b-aminobutyric acid (BABA)-primed potato to Phytophthora infestans. Plants exposed
to BABA rapidly modified their methylation capacity toward genome-wide DNA
hypermethylation. De novo induced DNA methylation (5-mC) correlated with the upregulation
of Chromomethylase 3 (CMT3), Domains rearranged methyltransferase 2
(DRM2), and Repressor of silencing 1 (ROS1) genes in potato. BABA transiently
activated DNA hypermethylation in the promoter region of the R3a resistance gene
triggering its downregulation in the absence of the oomycete pathogen. However, in
the successive stages of priming, an excessive DNA methylation state changed into
demethylation with the active involvement of potato DNA glycosylases. Interestingly,
the 5-mC–mediated changes were transmitted into the next generation in the form
of intergenerational stress memory. Descendants of the primed potato, which derived
from tubers or seeds carrying the less methylated R3a promoter, showed a higher
transcription of R3a that associated with an augmented intergenerational resistance
to virulent P. infestans when compared to the inoculated progeny of unprimed plants.
Furthermore, our study revealed that enhanced transcription of some SA-dependent
genes (NPR1, StWRKY1, and PR1) was not directly linked with DNA methylation
changes in the promoter region of these genes, but was a consequence of methylationdependent
alterations in the transcriptional network. | pl_PL |
