Lens epithelium-derived growth factor p75 (LEDGF/p75), member of the hepatoma-derived growth-factor-related protein (HRP) family, is a transcriptional co-activator and involved in several pathologies including HIV infection and malignancies such as MLL-rearranged leukemia. LEDGF/p75 acts by tethering proteins to the chromatin through its integrase binding domain. This chromatin interaction occurs between the PWWP domain of LEDGF/p75 and nucleosomes carrying a di- or trimethylation mark on histone H3 Lys36 (H3K36me2/3).

Article Synopsis
  • The study investigates the role of a protein called CCDC158 in kidney function, specifically in the reabsorption of proteins in the renal proximal tubules, highlighting its importance in kidney and reproductive health.
  • Whole exome sequencing identified a missense variant in CCDC158 in a male patient with kidney issues, which also appeared in a sister with similar symptoms, suggesting a hereditary component.
  • Functional analyses showed that CCDC158 likely interacts with other proteins involved in endocytosis, affecting kidney function and contributing to conditions like proteinuria and oligospermia, but further research is needed to clarify its exact mechanisms.

Spatial variability in soil pH is a major contributor to within-field variations in soil fertility and crop productivity. An improved understanding of the spatial variability of soil pH within agricultural fields is required to determine liming requirements for precision farming. This study with the use of proximal sensors, firstly assessed the spatial pattern of soil pH and how it can be used to determine site-specific, spatially variable lime requirements.

The sustainable cultivation of canola is under threat from clubroot disease (). The pathogen's resting spores can survive in the soil for extended periods, complicating disease management. Therefore, effective clubroot control requires a combination of tactics that provide multiple layers of protection.

Clubroot is a soilborne disease of canola () and other crucifers caused by the obligate parasite . In western Canada, clubroot is usually managed by planting-resistant cultivars, but the emergence of resistance-breaking pathotypes of represents a major threat to sustainable canola production. The rhizosphere and root contain beneficial microorganisms that can improve plant health.

Article Synopsis
  • - The study analyzed eight root system architecture (RSA) traits across 379 accessions from six plant species, revealing that two species had the largest and most complex root systems, while another species had the smallest roots.
  • - The research involved genotyping 313 accessions using a SNP array, filtering down to 6,213 significant markers for genome-wide association studies (GWAS), which identified 79 SNP markers tied to the RSA traits across various chromosomes.
  • - Major marker-trait associations were found on chromosomes A02, A03, and A06, with the results having potential significance for functional, environmental, and breeding applications in plant science.

is associated with the root rot of many plant species, but knowledge of its impact on western Canadian field crops is limited. This study assessed the host range of this fungus and its effect on plant emergence, plant height, and shoot and root dry weights in repeated greenhouse experiments with wheat, barley, faba beans, peas, lentils, canola, lupine, and soybeans. Infection was confirmed via PCR, and principal component analysis determined the utility of different parameters in assessing host responses.

  • In this study, a rutabaga donor parent (FGRA106) with strong resistance to various clubroot pathotypes was crossed with a susceptible canola (FG769) to analyze genetic inheritance.
  • The F plants were screened for resistance, revealing the inheritance of two main clubroot resistance genes, and RNA-sequencing identified 431, 67, and 98 differentially expressed genes between resistant and susceptible plants.
  • The research found a total of 12 quantitative trait loci (QTLs) associated with resistance, suggesting a genetic basis for the diverse resistance mechanisms and offering useful germplasm for breeding clubroot-resistant cultivars in Western Canada.

Unlabelled: The World Health Organization's goal to combat tuberculosis (TB) is hindered by the emergence of anti-microbial resistance, therefore necessitating the exploration of new drug targets. Multidrug regimens are indispensable in TB therapy as they provide synergetic bactericidal effects, shorten treatment duration, and reduce the risk of resistance development. The research within our European RespiriTB consortium explores energy metabolism to identify new drug candidates that synergize with bedaquiline, with the aim of discovering more efficient combination drug regimens.

  • - Macrophomina phaseolina is a fungal pathogen responsible for charcoal rot, affecting around 500 plant species globally, and it notably causes yield losses in soybean crops, particularly in eastern Canada and the USA, but has not been reported in western Canada.
  • - Manitoba, a significant soybean producer, has been conducting annual surveys for root diseases since 2012; however, charcoal rot’s presence was investigated following symptoms observed in soybeans from various fields there in August 2020.
  • - In a laboratory analysis of 600 roots from 40 fields, black streaking and other symptoms indicative of root rot were recorded, and pathogen isolation revealed black microsclerotia in cultures from three fields, leading to the identification of multiple fungal isolates.

Clubroot, caused by , is a soilborne disease of crucifers associated with the formation of large root galls. This root enlargement suggests modulation of plant hormonal networks by the pathogen, stimulating cell division and elongation and influencing host defense. We studied physiological changes in two cultivars, including plant hormone profiles-salicylic acid (SA), jasmonic acid (JA), abscisic acid (ABA), the auxin indole-3-acetic acid (IAA), and the ethylene precursor 1-aminocyclopropane-1-carboxylic acid (ACC)-along with their selected derivatives following inoculation with virulent and avirulent pathotypes.

Clubroot, caused by the obligate parasite , is one of the most devastating diseases affecting the canola/oilseed rape () industry worldwide. Currently, the planting of clubroot-resistant (CR) cultivars is the most effective strategy used to restrict the spread and the economic losses linked to the disease. However, virulent isolates have been able to infect many of the currently available CR cultivars, and the options to manage the disease are becoming limited.

Intermediate filaments (IFs) are essential constituents of the metazoan cytoskeleton. A vast family of cytoplasmic IF proteins are capable of self-assembly from soluble tetrameric species into typical 10-12 nm wide filaments. The primary structure of these proteins includes the signature central 'rod' domain of ~ 300 residues which forms a dimeric α-helical coiled coil composed of three segments (coil1A, coil1B and coil2) interconnected by non-helical, flexible linkers (L1 and L12).
