We determined the full-length genome sequence of Br48 and compared it with those of rice (70 - 15), finger millet (MZ5-1-6), and ryegrass (LpKY97) strains, for which the full-length genome sequences are available in the public databases. This article is an abstract of the presentation by a winner of the Society Fellowship at the 2023 Annual Meeting of the Phytopathological Society of Japan in Kanagawa (online). Instead, epigenetics involves DNA methylation, histone modifications and non-coding RNA-mediated processes as the molecular basis for gene regulation. When analyzed genome-wide, a significant correlation between a decrease in IPC levels and an increase in H3K27me3 levels was detected, suggesting that there is a relationship between HGT-derived genes and H3K27me3 levels in the Br48 genome, especially in the variable regions.
