AI Article Synopsis
- The study assessed the genetic diversity of wild hop populations in Central Italy by analyzing 12 populations and 6 commercial cultivars using 13 SSR loci.
- High levels of genetic variation were found, with 140 different genotypes identified among 159 samples, indicating a significant potential for gene flow within and between populations.
- The research also highlighted the presence of distinct genetic clusters and variability in the chemical qualities of hops, suggesting that these wild populations could be valuable resources for breeding new and improved hop varieties.
Article Abstract
In order to investigate the intraspecific diversity of wild Humulus lupulus (hop) in Central Italy, 12 populations were evaluated for their genetic polymorphism by means of 13 SSR loci together with six commercial cultivars as a reference. High levels of polymorphism were found across the populations, being 140 the number of multilocus genotypes over 159 samples analyzed. Moreover, the observed heterozygosity was higher than expected in most of the populations. High levels of gene flow were thus envisaged to occur within and among wild populations, and our sampling strategy allowed us to gain insights on the propagation modes of this species, i.e. clonal versus sexual propagation. Nevertheless, a genetic structure of populations with at least five genetically different clusters was disclosed. Private alleles were observed in both wild and cultivated hops. Chemical analysis of bittering and aromatic quality of female flowers from a subset of 8 wild populations revealed a high variability among plants, especially for essential oil components. Overall, the high variability of wild accessions here examined represent a valid source to be exploited in future breeding programs for new or improved hop cultivars development.

Background: Bacterial pathogens frequently encounter host-derived metabolites during their colonization and invasion processes, which can serve as nutrients, antimicrobial agents, or signaling molecules for the pathogens. The essential nutrient choline (Cho) is widely known to be utilized by a diverse range of bacteria and may undergo conversion into the disease-associated metabolite trimethylamine (TMA). However, the impact of choline metabolism on bacterial physiology and virulence remains largely unexplored.

Researchers have identified Avastrovirus as a significant genus of bird viruses, linked to various avian diseases such as enteritis, growth retardation, nephritis and hepatitis. These infections can cause substantial economic losses in agrocultureand have a widespread impact on global food production. Although there have been numerous studies on these viruses, most of them-mainly focuses on poultry.

Landraces are a critical genetic resource for resilience breeding, offering solutions to prepare agriculture for the challenges posed by climate change. Their efficient utilisation depends on understanding their history and genetic relationships. The current study investigates the phylogenetic relationships of barley landraces from Algeria, varieties from the Near and Middle East, traditional landraces, and modern cultivars from Europe.

Despite its importance in pathogenesis, the hematogenous dissemination pathway of is still largely uncharacterized. To probe the molecular details of transendothelial migration more easily, we studied this process using cultured primary or telomerase-immortalized human microvascular endothelial cells in a medium that maintains both the human cells and the spirochetes. In -infected monolayers, we observed ~55% of wild-type spirochetes crossing the monolayer.
