Project description:We analyzed the transcriptome of A. acutangulus roots by deep RNA sequencing to dig TAs biosynthetic genes. KOG (Eukaryotic Orthologous Groups) and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway enrichment analyses identified 48 unigenes referring to the tropane, piperidine and pyridine alkaloid biosynthesis, 145 unigenes presumably involved in distribution of arginine to TAs biosynthesis, and 86 unigenes referring to the terpenoid backbone biosynthesis. Furthermore, 82 unigenes annotated as cytochrome P450 family members seemed to be involved in secondary metabolism pathways. Previously unknown TAs biosynthetic genes in A. acutangulus, which encode littorine mutase/monooxygenase (CYP80F1) and diamine oxidase (DAO), were identified by this study.
Project description:This study aims to investigate the DNA methylation patterns at transcription factor binding regions and their evolutionary conservation with respect to binding activity divergence. We combined newly generated bisulfite-sequencing experiments in livers of five mammals (human, macaque, mouse, rat and dog) and matched publicly available ChIP-sequencing data for five transcription factors (CEBPA, HNF4a, CTCF, ONECUT1 and FOXA1). To study the chromatin contexts of TF binding subjected to distinct evolutionary pressures, we integrated publicly available active promoter, active enhancer and primed enhancer calls determined by profiling genome wide patterns of H3K27ac, H3K4me3 and H3K4me1.
