Unlocking saponin biosynthesis in soapwort - Nature Chemical Biology
Abstract Soapwort (Saponaria officinalis) is a flowering plant from the Caryophyllaceae family with a long history of human use as a traditional source of soap. Its detergent properties are because of the production of polar compounds (saponins), of which the oleanane-based triterpenoid saponins, saponariosides A and B, are the major components. Soapwort saponins have anticancer properties and are also of interest as endosomal escape enhancers for targeted tumor therapies.
Seagrass genomes reveal ancient polyploidy and adaptations to the marine environment - Nature Plants
|
Abstract We present chromosome-level genome assemblies from representative species of three independently evolved seagrass lineages: Posidonia oceanica, Cymodocea nodosa, Thalassia testudinum and Zostera marina. We also include a draft genome of Potamogeton acutifolius, belonging to a freshwater sister lineage to Zosteraceae. All seagrass species share an ancient whole-genome triplication, while additional whole-genome duplications were uncovered for C. nodosa, Z. marina and P. acutifolius.

Genome analyses reveal population structure and a purple stigma color gene candidate in finger millet - Nature Communications
Genome sequencing Seed from a single self-pollinated plant of E. coracana subsp. coracana accession KNE 796-S was planted in trays and grown under artificial lighting (14 h days) at 27 °C. Seedlings were harvested approximately one month postemergence. For DNA extractions59, frozen leaves were ground to a fine powder in liquid nitrogen in a precooled mortar and gently extracted in a CTAB buffer that included proteinase K, PVP-40 and β-mercaptoethanol for 1 h at 50 °C.
Newly identified sex chromosomes in the Sphagnum (peat moss) genome alter carbon sequestration and ecosystem dynamics - Nature Plants
Abstract Peatlands are crucial sinks for atmospheric carbon but are critically threatened due to warming climates. Sphagnum (peat moss) species are keystone members of peatland communities where they actively engineer hyperacidic conditions, which improves their competitive advantage and accelerates ecosystem-level carbon sequestration. To dissect the molecular and physiological sources of this unique biology, we generated chromosome-scale genomes of two Sphagnum species: S. divinum and S.
Genome of Paspalum vaginatum and the role of trehalose mediated autophagy in increasing maize biomass - Nature Communications
Abstract A number of crop wild relatives can tolerate extreme stress to a degree outside the range observed in their domesticated relatives. However, it is unclear whether or how the molecular mechanisms employed by these species can be translated to domesticated crops. Paspalum (Paspalum vaginatum) is a self-incompatible and multiply stress-tolerant wild relative of maize and sorghum. Here, we describe the sequencing and pseudomolecule level assembly of a vegetatively propagated accession of P.
Dynamic genome evolution in a model fern - Nature Plants
Abstract The large size and complexity of most fern genomes have hampered efforts to elucidate fundamental aspects of fern biology and land plant evolution through genome-enabled research. Here we present a chromosomal genome assembly and associated methylome, transcriptome and metabolome analyses for the model fern species Ceratopteris richardii.
