Summary: In order to fill in the information gap regarding plum tree viruses in Bosnia and Herzegovina, a three-phase study combining symptom evaluation, serological and molecular assays, and high-throughput sequencing (HTS) technology was conducted. The study found that PPV was the most prevalent virus, followed by PDV and PNRSV. HTS enabled the recovery of virus sequences and phylogenetic analysis.

Summary: The study revealed the development process of stem pitting in citrus plants infected with Citrus tristeza virus (CTV), showing that the virus invades protophloem, metaphloem, and unexpected metaxylem cells, disrupting the differentiation of xylem tracheary elements and leading to the formation of stem pits. This provides new insights into the role of xylem tissue in virus pathogenicity.

Summary: Researchers have developed methods for detecting the genetic diversity of grapevine rupestris stem pitting-associated virus (GRSPaV) and found that there is a discrepancy rate between RFLP and SSCP in showing the degree of diversity.

Summary: This review summarizes the history and current state of the genetic basis for soybean resistance to Soybean mosaic virus (SMV) and the application of molecular markers in crop improvement. It discusses the molecular underpinnings of SMV-soybean interactions and the distribution and interactions of resistance genes. Although the physical position of some resistance genes has been identified, there are still elusive causative genes. Soybean resistance to SMV has been achieved through the combination of multiple genes.

Summary: This study analyzed the genetic variation and phylogenetics of apple chlorotic leaf spot virus (ACLSV) and apple stem grooving virus (ASGV) using nucleotide and amino acid sequences from wild apple. The results identified known groups and novel clades within ACLSV, as well as separate groups within ASGV. Recombinant sequences were also identified in ACLSV and potential recombination events were found in ASGV. These findings provide valuable insights into the variability of virus genetics and pathogenicity.

Summary: The study identified different isolates of Apple stem grooving virus in agricultural fields in South Korea, showing phylogenetic separation based on their host species rather than geography. Further analysis indicated that the virus followed host adaptation influenced by the host codon usage.

Summary: The genetic relationships, population structure, and diversity of 45 apple genotypes were examined using a SNP array, revealing mislabeled accessions and redundancies in apple germplasm. SNP markers showed better differentiation ability compared to SSR markers and were able to cluster accessions based on their pedigree. The study also uncovered some genetic relationships and the introgression of 'Delicious' and 'Golden Delicious' into the core collection.

Summary: This study investigated the transcriptome changes in Citrus macrophylla trees infected with different Citrus tristeza virus mutants. The results showed that the expression of specific genes related to xylem differentiation, phloem and cambium development, and cell cycle re-entry were associated with the development of stem pitting symptoms. The findings suggest that phloem regeneration may contribute to the development of stem pitting symptoms.

Summary: This study revealed the widespread infection of apple stem grooving virus (ASGV), apple chlorotic leaf spot virus (ACLSV), and apple stem pitting virus (ASPV) in maternal trees of P. betulifolia and P. calleryana. The positive rates for these viruses in seeds ranged from 15.9% to 73.9% for ASGV, 0% to 21.2% for ASPV, and 40.4% for ACLSV. This study also analyzed the genetic variation of these viruses and found close relationships with reported isolates infecting pear.

Summary: This study investigates the diversity of newly discovered bumblebee viruses in Scotland and finds that they are more genetically diverse than viruses shared with honeybees. The presence of multiple infections and environmental factors such as temperature and UV radiation play important roles in shaping viral prevalence. This research represents an initial step in understanding predictors of bumblebee infection in the wild.
