Cherries are stone fruits and belong to the economically important plant family of Rosaceae with worldwide cultivation of different species. The ground cherry, Prunus fruticosa Pall., is an ancestor of cultivated sour cherry, an important tetraploid cherry species. Here, we present a long read chromosome-level draft genome assembly and related plastid sequences using the Oxford Nanopore Technology PromethION platform and R10.3 pore type. We generated a final consensus genome sequence of 366 Mb comprising eight chromosomes. The N50 scaffold was ~44 Mb with the longest chromosome being 66.5 Mb. The chloroplast and mitochondrial genomes were 158,217 bp and 383,281 bp long, which is in accordance with previously published plastid sequences. This is the first report of the genome of ground cherry (P. fruticosa) sequenced by long read technology only. The datasets obtained from this study provide a foundation for future breeding, molecular and evolutionary analysis in Prunus studies.

Crop genomes accumulate deleterious mutations-a phenomenon known as the cost of domestication. Precision genome editing has been proposed to eliminate such potentially harmful mutations; however, experimental demonstration is lacking. Here we identified a deleterious mutation in the tomato transcription factor SUPPRESSOR OF SP2 (SSP2), which became prevalent in the domesticated germplasm and diminished DNA binding to genome-wide targets.

To explore potential anti-inflammatory lead compounds, ten new physalin steroids, including three neophysalins (1, 4, and 9) and seven physalins (2, 3, 5-8, and 10), along with eleven known analogs, were isolated from an ethanol extract of the calyx of Physalis alkekengi. The new structures were rigorously determined through comprehensive HRESIMS, 1D/2D-NMR, and X-ray diffraction analysis. Among these compounds, 1 was identified as a new 1,10-seco-neophysalin, and 2 was identified as a new 11,15-cyclo-9,10-seco-physalin characterized by an aromatic A-ring.

Physalis alkekengi L. is recognized as a significant source of various secondary metabolites, particularly C steroidal lactones known as withanolides and physalins, renowned for their therapeutic properties with a rich history in traditional medicine. In this study, we characterized the sequences of key downstream genes (PaFPPS, PaSQS, PaSQE, PaCAS, PaHYD1, and PaDWF5-1) involved in the biosynthesis of withanolides, marking the first characterization of these genes in P.

Our recent steady-state mass-balance modeling suggests that most global carbonic-acid weathering of silicate rocks occurs in the vadose zone of aquifer systems not on the surface by atmospheric CO. That is, the weathering solute flux is nearly equal to the total global continental riverine carbon flux, signifying little atmospheric weathering by carbonic acid. This finding challenges previous carbon models that utilize silicate weathering as a control of atmospheric CO levels.
