The present study investigates the effects of exogenous salicylic acid (SA) on the expression of () gene under low-temperature conditions in an Iranian L. 'Sultanina'. The experiment was conducted as a factorial experiment based on a completely randomized design with four replications. 100 μmol/L SA (0, 1, 6 and 12 h before applying cold stress) in temperatures of 1 ± 0.5 °C (for 1, 3, 6 and 12 h) and 22 °C (as control) were applied. The highest expression was observed in plants treated 6 h before sampling. By increasing the duration of low temperature, the expression of increased. Increasing the duration of cold stress to 6 h in 1 °C increased the expression of to 24.3 fold. Exogenous application of SA and cold stress treatments increased the expression of . In conclusion, exogenous application of SA in cold stress, increased the expression of depending on treating time before cold stress. The highest expression was observed in plants treated 6 h before sampling and increasing the time decreased the expression. By increasing the expression of the tolerance of plant to cold stress increased.

Skeletal muscle is a critical organ in maintaining homoeostasis against metabolic stress, and histone post-translational modifications are pivotal in those processes. However, the intricate nature of histone methylation in skeletal muscle and its impact on metabolic homoeostasis have yet to be elucidated. Here, we report that mitochondria-rich slow-twitch myofibers are characterized by significantly higher levels of H3K36me2 along with repressed expression of Kdm2a, an enzyme that specifically catalyses H3K36me2 demethylation.

Understanding the molecular mechanisms that confer cold resistance in mammalian cells might be relevant for advancing medical applications. This study aimed to exploit the protective function of Late Embryogenesis Abundant (LEA) proteins, known to provide resistance to low temperatures in extremophiles and plants, by their exogenous expression in mammalian cells, and compare their effects with the well characterized antioxidant, vitamin E.Remarkably, the expression of LEA proteins in mammalian cells exerted cold-protective effect similar to Vitamin E.

The coronavirus HCoV-OC43 circulates continuously in the human population and is a frequent cause of the common cold. Here, we generated a high-resolution atlas of the transcriptional and translational landscape of OC43 during a time course following infection of human lung fibroblasts. Using ribosome profiling, we quantified the relative expression of the canonical open reading frames (ORFs) and identified previously unannotated ORFs.

Cold stress (CS) is a significant natural hazard, and distinguishing between plant cold resistance and sensitivity is critical for cultivar breeding and the development of germplasm resources. This study used 205 tobacco (Nicotiana tabacum L.) varieties from around the world to investigate the changes in the chlorophyll a fluorescence (OJIP) transients, JIP-test parameters, and seedling growth caused by seven days of CS (5°C) treatment.

Background And Aims: Understanding interspecific differences in plant growth rates and their internal and external drivers is key to predicting species responses to ongoing environmental changes. Annual growth rates vary among plants based on their ecological preferences, growth forms, ecophysiological adaptations, and evolutionary history. However, the relative importance of these factors remains unclear, particularly in high-mountain ecosystems experiencing rapid changes.
