Published: June 2020

Familial cold inflammatory syndrome (FCAS) is a rare, inherited inflammatory disease characterized by episodes of fever, rash, and arthralgias after exposure to cold stimuli. Previous literature has established FCAS linked to autosomal dominant mutations in the NLRP3 (CIAS1) and NLRP12 genes. Moreover, there has been recent evidence of NLRC4-inflammasomopathies. Although there have been cases of FCAS secondary to missense mutations in NLRC4, we report the first symptomatic case associated with a 93-base-pair in-frame deletion within Exon 5 of the leucine rich repeat domain.

Helotiales, a diverse fungal order within Leotiomycetes (Ascomycota), comprises over 6000 species occupying varied ecological niches, from plant pathogens to saprobes and symbionts. Despite their importance, their genetic adaptations to temperature and environmental conditions are understudied. This study investigates temperature adaptations in infection genes and substrate degradation genes through a comparative genomics analysis of 129 Helotiales species, using the newly sequenced genomes of and .

During the dormant period of peach trees in winter, flower buds exhibit weak cold resistance and are susceptible to freezing at low temperatures. Understanding the physiological and molecular mechanisms underlying the response of local peach buds to low-temperature adversity is crucial for ensuring normal flowering, fruiting, and yield. In this study, the experimental materials included the conventional cultivar 'Xia cui' (XC) and the cold-resistant local resources 'Ding jiaba' (DJB) peach buds.

Article Synopsis
  • The homedomain-leucinezippper gene family influences plant growth and drought response, with ArHDZ19 being a key transcription factor from Anoectochilus roxburghii whose role was studied.
  • ArHDZ19 is localized in the nucleus and its expression increases significantly under drought stress; overexpressing this gene in Arabidopsis thaliana led to taller plants, longer reproductive structures, and earlier flowering.
  • Additionally, while ArHDZ19 enhances plant survival in drought conditions, it appears to modulate the expression of certain stress-responsive genes, suggesting it aids drought resistance through promoting earlier flowering as a potential avoidance strategy.

Amaranth is an ancient crop of the family Amaranthaceae, but it is fairly new to Russia. Its seeds and leaf biomass contain a high-quality gluten-free protein, fatty acids, squalene (a polyunsaturated hydrocarbon), flavonoids, vitamins, and minerals. A comprehensive study of amaranth, enhancement of its breeding, and development of new cultivars will contribute to food quality improvement through the use of plant raw materials enriched for wholesome and highly nutritious components.

Rainbow trout () is a promising cultivable fish species with significant potential for expansion. As a cold-water fish belonging to the Salmonidae family, it requires an optimal temperature range of 10-15°C for optimal growth. This study explores a method for producing sterile rainbow trout with maximum survival rates by using heat shock treatment to enhance growth characteristics and improve aquaculture practices.
