Summary: Plants are highly adaptable to changing adverse environmental conditions, particularly in response to oxygen levels which have significant impacts on growth and development. The transition from hypoxia to reoxygenation can lead to cell damage due to oxidative stress, and further research is needed to understand this process. Studying molecular events related to gene expression regulation during hypoxia and reoxygenation will be crucial for improving agricultural biotechnology in the context of global climate change.

Summary: Plants have the ability to adapt to different environmental conditions and respond to adverse challenges by modulating their genetic information and transmitting signals between different parts. Stress priming, particularly thermo-priming, is an important phenomenon where plants modify cellular and molecular parameters as a memory of mild stress exposure, enhancing their tolerance to severe stress. This review discusses the different ways plants can be primed and the biochemical and molecular changes involved, as well as the role of various hormones in priming under changing climate conditions.

Summary: Abiotic stresses caused by climate change are a major reason for global crop losses, impairing physiological, biochemical, molecular, and cellular mechanisms in plants. Plants have evolved adaptations and defense mechanisms to counteract these stresses. Recent research indicates that signaling molecule hydrogen sulfide (H2S) plays a crucial role in mitigating environmental stress effects in plants by implementing various physiological and biochemical mechanisms. Further understanding and utilizing H2S's protective role through genetic engineering methods is necessary for enhancing stress tolerance in crops.

Summary: Abiotic stress refers to the adverse effect of non-biological factors on plants in a given environment, affecting their growth and development. These stress factors, such as drought, salinity, and extreme temperatures, are often interconnected. Plants have developed mechanisms to sense and adapt to these environmental challenges. This review summarizes recent studies on plant stress sensing and regulatory mechanisms, focusing on signal transduction and regulation at multiple levels. The strategies to improve plant growth under stress based on current progress are also discussed. Moreover, the implications of understanding plant responses to abiotic stresses for high-yielding crops and agricultural sustainability are explored. Studying stress signaling and regulation is crucial for comprehending plant responses to abiotic stress, developing stress-resistant crops, and promoting agricultural sustainability.

Summary: Protein S-acylation, also known as palmitoylation, is a vital lipid post-translational modification in eukaryotes, playing critical roles in plant development and responses to various stresses. The dynamic and reversible nature of S-acylation allows membrane-associated proteins to undergo cycling and trafficking, acting as a switch in signaling transductions. While numerous S-acylated proteins have been identified in plants, the understanding of the regulatory mechanisms controlling this process remains incomplete.

Summary: Nitric oxide (NO), a colorless gaseous molecule, plays a crucial role in plant growth, development, and responses to biotic and abiotic stresses. It interacts with reactive oxygen species, antioxidants, melatonin, and hydrogen sulfide, regulates gene expression, and modulates phytohormones. However, the key enzyme in NO production, nitric oxide synthase, has been poorly understood recently in both model and crop plants.

Summary: Cold stress is a significant environmental factor affecting plant growth and distribution, resulting in reduced yield. Plants have evolved molecular mechanisms to survive in cold conditions. The major regulatory pathway for low-temperature stress involves converting external stimulus into an internal signal, which triggers a defense mechanism through transcriptional cascade. This review discusses the regulatory mechanisms underlying cold stress, including signal molecules, cold receptors, signal transduction pathways, metabolic regulation under cold stress, and the interaction with other abiotic stresses in plants. The findings may contribute to crop improvement in low-temperature environments.

Summary: This study assessed the genetic diversity of Oxytropis species and the levels of endophytes and swainsonine. The results showed that species variation, genetic drift, and genotype x environment effects are associated with the fixation or loss of endophytes and swainsonine production in the Oxytropis genus. This study provides a better understanding of the evolutionary basis of A. oxytropis symbiosis and swainsonine biosynthesis in locoweeds.

Summary: This study conducted whole genome sequencing of the most common locoweed in China and obtained a high-quality, chromosome-level reference genome. The toxicity of locoweed is related to the mycotoxin swainsonine produced by symbiotic endophytes. The genomes of Oxytropis ochrocephala and A. oxytropis were analyzed, and the genes involved in swainsonine biosynthesis were refined. The study also identified differentially expressed genes related to defense and secondary metabolism in the host.

Summary: Salinity-induced metabolite responses in tef seedlings showed differential accumulation of flavonoids and antioxidant metabolites in shoots and roots, which suggested an improved antioxidant capacity for salt adaptation. In this study, 19 tef varieties were screened for salt tolerance and investigated using metabolomic approaches. The results showed significant differences in germination rates and root pigmentation among the varieties under NaCl treatment. The salt-tolerant tef varieties accumulated flavonoid derivatives, sugars, and cell wall associated metabolites in their roots, demonstrating a mitigating response to salinity.

Summary: Based on the data analysis of GBD 2019, the global population of older adults has increased since 1990, and overall mortality rates have decreased for both men and women. However, mortality rates due to falls have increased during the same period. The probability of death among people aged 70-90 has decreased, mainly due to reductions in non-communicable diseases. Globally, disability burden is mainly driven by functional decline, vision and hearing loss, and symptoms of pain. Life expectancy at age 70 (LE-70) and healthy life expectancy at age 70 (HALE-70) have shown continuous increases since 1990, with regional disparities. Higher LE-70 results in higher HALE-70 and slightly increased proportion of years in ill health at age 70 (PYIH-70). Sociodemographic factors, healthcare access and quality indices are positively correlated with HALE-70 and LE-70. Limited data are available for various dietary, environmental or occupational, and metabolic risks.
