Project description:Legumes have evolved lineage-specific peptides to control rhizobia and sustain nitrogen fixation. In inverted repeat-lacking clade (IRLC) legumes, nodule-specific cysteine-rich (NCR) peptides enforce terminal bacteroid differentiation, maximizing symbiotic output but restricting nodule lifespan. By contrast, Robinioid legumes, the IRLC’s sister clade, lack NCRs yet yet include perennial species that maintain productive nodules for decades. Here we identify a nodule-proline-glycine-rich peptide family (NPGs) as a conserved, genus-wide innovation of Robinia. NPGs are highly abundant, localize to the symbiosome membrane, and are intrinsically disordered. Exposure of Mesorhizobium robiniae to recombinant NPGs reprograms physiology, inducing nitrogenase expression while dampening growth without loss of viability. NPGs thus exemplify a distinct, reversible strategy of symbiont control, expanding the peptide repertoire that supports nitrogen fixation in perennial legumes.

Project description:Cytosine methylation is a base modification that is often used by genomes to store information that is stably inherited through mitotic cell divisions. Most cytosine DNA methylation is stable throughout different cell types or by exposure to different environmental conditions in plant genomes. Here, we profile the epigenomes of ~100 Glycine max lines to explore the extent of natural epigenomic variation. We also use these data to determine the extent to which DNA methylation variants are linked to genetic variations.

Project description:The R-loop is a common chromatin feature presented from prokaryotic to eukaryotic genomes and has been revealed to be involved in multiple cellular processes and associated with many human diseases. Here, we take the advantage of our recently developed ssDRIP-seq method to profile genome-wide R-loop levels of soybean (Glycine max).
