Summary: This article provides a revision of the genera Gloriosa and Sandersonia in southern Africa, including detailed descriptions, distribution data, and conservation assessments. The article also presents color illustrations of all species. The study distinguishes three species of Gloriosa based on flower shape and size, and style orientation and length. It also describes the unique features of the monotypic genus Sandersonia. This research provides important reference material for the classification and naming of these species.

Summary: Defects in crossover (CO) formation during meiosis due to maternal aging can lead to increased aneuploidy and decreased oocyte quality in nematode worms. Mutations in genes encoding double-strand break (DSB)-associated proteins show more severe phenotypes with age, indicating a sensitive node in reproductive aging. Aging affects the integrity of meiotic crossover formation, with reductions in DNA binding proteins and compromised repair capacity seen in early aging phenotypes.

Summary: During meiosis, DMC1 plays a central role in repairing DNA double-strand breaks through homologous recombination. The function of DMC1 is regulated by accessory proteins and bivalent ions, including calcium ions. This study reveals that calcium ions induce a conformational change in DMC1, enhancing its DNA binding and D-loop formation, while inhibiting the extension of the invading strand within the D-loop. Mutations in two highly conserved amino acids of human DMC1, which affect its calcium regulation, result in severe defects in meiosis.

Summary: In Drosophila spermatocytes, homolog pairing does not involve synaptonemal complex formation and crossovers, but instead avoids non-homologous associations through chromosome territory formation. Mutations in Cap-D3 and Cap-H2 disrupt chromocenter and result in chromosome missegregation during meiosis I. While condensin II activity is crucial for chromosome territory formation, additional force generators may be needed for extensive separation of bivalents.

Summary: This study performed a comparative analysis of Helicobacter species to investigate the variability and evolutionary origin of virulence factors (VF). The results identified microevolutionary events in urease and flagella genes during the evolution of this genus. The findings also revealed genetic differences between gastric Helicobacter species (GHS) and enterohepatic species (EHS) and their relationship with pathogenicity.

Summary: This study used a cytogenomic approach to investigate the relationship between synaptonemal complex length and DNA content in chicken oocytes during the pachytene stage of the first meiotic prophase. Results showed variations in DNA packing ratios of macro- and microbivalents, as well as differences in synaptonemal complex length based on recombination rates. Higher crossover rates were associated with comparatively longer synaptonemal complexes due to the formation of shorter DNA loops in regions with higher recombination levels.

Summary: Heavy metal pollution is a global concern, and phytoremediation using plants and associated microorganisms has been effective in removing heavy metals from contaminated sites. The Typha genus is particularly suitable for phytoremediation because of its rapid growth, high biomass production, and ability to accumulate heavy metals. Plant growth-promoting rhizobacteria have also been studied for their ability to improve plant growth and tolerance to heavy metals. This review discusses the phytoremediation process, the application of Typha species, and the bacterial communities associated with their roots in both contaminated and non-contaminated environments, highlighting the importance of Proteobacteria in these communities.

Summary: Considering consumer demands and competition among producers, the quality of food is highly important. The sensory quality of herbs and spices also raises concerns. This research found that changes in enantiomeric distribution occur during the drying process, but there are no clear correlations or trends for individual chiral components. Additionally, judges were not able to effectively match sample essential oils (EOs) and plant samples. Therefore, instrumental analysis cannot predict general sensory quality.

Summary: Antimicrobial resistance is a global concern and wild boar may play a role in spreading Salmonella, which is critical for the effectiveness of antibiotics. This study detected widespread antimicrobial resistance in Salmonella from wild boar in different game estates in central Spain, and found that feeding supplementation and surrounding fences on game estates increased the antimicrobial resistance of Salmonella.

Summary: The study evaluates the systematics and phylogeny of the Cretaceous genus Aegocrioceras using quantitative morphometrics on specimens from north-west Germany. The simplified systematics of the genus consists of three entities: A. bicarinatum [m]-A. semicinctum [M] complex, A. raricostatum, and A. spathi. The most likely phylogeny aligns well with the stratigraphic record of the species and suggests anagenetic adaptations in two species after their origin. Aegocrioceras likely derived from warm-water adapted Tethyan Crioceratites species, with Boreal Crioceratites potentially representing warm-water adapted descendants of Aegocrioceras or renewed Tethyan invasions. The success of Aegocrioceras in the Boreal region is attributed to abiotic change processes due to its high adaptability, while selection within the Aegocrioceras clade is more likely based on biotic interaction processes.
