Rosaceae is the most important fruit-producing clade, and its key commercially relevant genera (Fragaria, Rosa, Rubus and Prunus) show broadly diverse growth habits, fruit types and compact diploid genomes. Peach, a diploid Prunus species, is one of the best genetically characterized deciduous trees. Here we describe the high-quality genome sequence of peach obtained from a completely homozygous genotype. We obtained a complete chromosome-scale assembly using Sanger whole-genome shotgun methods. We predicted 27,852 protein-coding genes, as well as noncoding RNAs. We investigated the path of peach domestication through whole-genome resequencing of 14 Prunus accessions. The analyses suggest major genetic bottlenecks that have substantially shaped peach genome diversity. Furthermore, comparative analyses showed that peach has not undergone recent whole-genome duplication, and even though the ancestral triplicated blocks in peach are fragmentary compared to those in grape, all seven paleosets of paralogs from the putative paleoancestor are detectable.

Background: Fruit acidity and color are important quality attributes in peaches. Although there are some exceptions, blood-fleshed peaches typically have a sour taste. However, little is known about the genetic variations linking organic acid and color regulation in peaches.

Background: Pesticides are widely used in agriculture to control pests and enhance crop yields. However, post-harvest, there are growing concerns about the potential health risks posed by pesticide residues on produce surfaces. Analyzing these residues is challenging due to their typically low concentrations and the potential interference from the complex matrix of the produce's surface.

Introduction: Taohong Siwu decoction (THSWD), a traditional prescription for enhancing blood circulation and eliminating blood stasis, primarily comprises peach kernel, safflower, angelica, chuanxiong, and rehmannia. Modified Taohong Siwu decoction (MTHSWD), an advanced version of THSWD, incorporates additional ingredients such as epimedium, cinnamon, and salvia miltiorrhiza. This addition serves to augment its efficacy in warming yang and promoting blood circulation.

Introduction: The ability to admit patients to enhanced or critical care may be limited by bed availability. In a network with low provision of critical and enhanced care beds, we aimed to assess the proportion of patients having surgery with moderate (1%-< 5%) or high (≥ 5%) predicted risk of 30-day postoperative mortality and their postoperative care location. We also aimed to study referral and admission outcomes to critical care.

Human DNA licensing initiates replication fork assembly and DNA replication. This reaction promotes the loading of the hMCM2-7 complex on DNA, which represents the core of the replicative helicase that unwinds DNA during S-phase. Here, we report the reconstitution of human DNA licensing using purified proteins.
