Tropical forage grasses, particularly those belonging to the genus, play a crucial role in cattle production and serve as the main food source for animals in tropical and subtropical regions. The majority of these species are apomictic and tetraploid, highlighting the significance of , a sexual diploid species that can be tetraploidized for use in interspecific crosses with apomictic species. As a means to support breeding programs, our study investigates the feasibility of genome-wide family prediction in families to predict agronomic traits.

- The study presents the highest-density genetic map for Urochloa humidicola, highlighting its genetic organization, reproductive methods, and species origin, which are crucial for breeding and research on tropical forage grasses.
- Urochloa humidicola, an essential tropical pasture grass for poorly drained soils, presents challenges in genetic analysis due to its complex genome and reproduction through apomixis, complicating marker-assisted selection (MAS).
- The researchers created a detailed linkage map using SNP markers, revealing key genetic information about the species and identifying genetic traits related to apomixis, which could aid in developing better forage grasses.
Molecular marker discovery and genotyping are major challenges in polyploid breeding programs incorporating molecular biology tools. In this context, this work describes a method for single nucleotide polymorphism (SNP) genotyping in polyploid crops using matrix-assisted laser desorption ionization (MALDI) time-of-flight (TOF) mass spectrometry, the MassARRAY System.

- Poaceae is a diverse plant family that includes key crops like forage grasses and sugarcane, which face challenges in genetic research due to their complex genomic structures.
- The study focuses on developing a machine learning approach to improve the prediction of complex traits in these polyploid species, utilizing genotypic data from sugarcane and forage grasses.
- The new predictive system outperformed traditional methods, showing over 50% improvements in accuracy, which could streamline breeding programs and enhance genetic advancements.
Pastures based on perennial monocotyledonous plants are the principal source of nutrition for ruminant livestock in tropical and subtropical areas across the globe. The genus comprises important species used in pastures, and these mainly include , , , and . Despite their economic relevance, there is an absence of genomic-level information for these species, and this lack is mainly due to genomic complexity, including polyploidy, high heterozygosity, and genomes with a high repeat content, which hinders advances in molecular approaches to genetic improvement.

Material And Methods: Subgingival samples were collected from subjects with ChP (n = 3/category of probing depth: ≤3, 4-6 and ≥7 mm) and periodontal health (PH). Individual samples were submitted to 16S rDNA high- throughput sequencing and the analysis was made using mothur and R packages.
We report here the sequence of the entire chromosome of Staphylococcus aureus strain FCFHV36, a methicillin-resistant strain heterogeneously intermediate to vancomycin, bearing a type II staphylococcal chromosome cassette mec element (SCCmec), belonging to multilocus sequence type (MLST) 105, and isolated from a vertebra of a patient with osteomyelitis.
