Project description:Aluminum (Al) toxicity is one of the major factors limiting crop growth in acid soils. Al inhibits root growth, reducing crop yield. Carpetgrass (Axonopus compressus) is a dominant warm-season turfgrass of Gramineae, and is widely distributed in tropical and subtropical areas. Carpetgrass with great potential for Al toxicity tolerance is an excellent grass plant to investigate the mechanism of plant adaptation to Al toxicity. However, the molecular mechanisms of Al-responsive are still unclear in carpetgrass. Therefore, the purpose of this study was to identify candidate Al tolerance genes by genome-wide transcriptome analysis of carpetgrass root in response to Al toxicity. Through RNA-seq analysis, we identified 1351 up-regulated and 485 down-regulated genes to Al toxicity.

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.
