Summary: Changes in water balance pose significant challenges for aeroterrestrial algae, who have various mechanisms to combat osmotic stress and ionic stress. While some algae can adapt to both salt and desiccation stress, such as Stichococcus bacillaris Nageli, others may exhibit variable tolerance levels. The ecological niches of algae are defined by their ability to withstand different environmental stresses.

Summary: Desiccation tolerance is a key adaptation feature of photoautotrophic organisms in terrestrial habitats. Vascular plants have developed complex anatomy structures and molecular mechanisms to maintain cell hydration, with different genes encoding mechanisms playing varying roles in different stages of plant evolution.Mechanisms behind desiccation tolerance include LEA proteins, sHSP, oligosaccharides, and antioxidants, activated during late seed maturation stage. Regulation is controlled by abscisic acid and protein DOG1, along with a network of transcription factors and epigenetic regulation.

Summary: Listeria monocytogenes uses cold shock proteins (Csps) to respond to stress and adapt to changing environmental conditions, affecting biofilm formation, motility, cold, osmotic, desiccation, and oxidative stress tolerance. Csps play a role in overall virulence by impacting the expression of virulence-associated phenotypes, such as hemolysis and cell invasion. Differences in Csps roles among strains from different genetic backgrounds are apparent for desiccation tolerance and biofilm production, showing hierarchical trends and functional redundancies in stress tolerance and virulence.

Summary: This study demonstrates the important role of F-box protein SKIP31 in regulating late seed maturation, seed vigor, and viability in Arabidopsis. SKIP31 interacts with JAZ proteins, directing their degradation independently of JA-Ile. JAZ proteins interact with ABI5 and repress its transcriptional activity, while SKIP31 targets JAZ proteins, deregulates ABI5 activity, and positively regulates seed maturation and vigor.

Summary: Our study demonstrated that Arabidopsis HSP70-16 and VDAC3 work together to suppress seed germination under cold stress conditions by facilitating the efflux of ABA from the endosperm to the embryo. The interaction between HSP70-16 and VDAC3 activates the opening of the VDAC3 ion channel, which influences ABA efflux from endosperm to embryo and negatively regulates seed germination under cold stress.

Summary: This study investigated the cold tolerance of sorghum in high altitudes and temperate regions under early, mid, and standard planting dates, finding that delayed panicle initiation and reduced panicle size were the main reasons for decreased grain yields under early and mid-planting dates. The study revealed that panicle width and area were significant predictors of yield under early and mid-planting dates.

Summary: Climate change caused by global warming is now affecting agricultural production worldwide. In rice, water limitation due to irregular rainfall in rainfed lowlands during crop growth is a major factor limiting yield. Dry direct-sowing has been suggested as a water-efficient approach to cope with water stress during rice growth, but poor seedling establishment due to drought during germination and emergence remains a problem.

Summary: This study revealed that GhHAI2, GhAHG3, and GhABI2 act as negative regulators in the osmotic stress response in cotton through ABA-mediated signaling. Silencing of these genes improved osmotic tolerance in cotton, leading to decreased water loss, increased relative water content and photosynthetic gas exchange, higher antioxidant enzyme activity, and lower malondialdehyde content.

Summary: Some ant species adapt to hot and arid environments by varying worker size and morphology, which enhances resistance to heat stress. Water content, water loss, and protein regulation play a key role in thermal resistance. Large and polymorphic ants are better at tolerating heat stress, while small and monomorphic ants have different adaptive strategies.

Summary: Enhanced cold tolerance in watermelon shoots due to pumpkin or figleaf gourd rootstock is associated with increased accumulation of melatonin, methyl jasmonate (MeJA), and hydrogen peroxide (H2O2). Melatonin is involved in grafting-induced cold tolerance by inducing the accumulation of MeJA and H2O2, forming a self-amplifying feedback loop that leads to increased H2O2 accumulation and cold tolerance.

Summary: This study investigated the response mechanism of microalgae under heat and cold stress. The results showed that heat stress led to a significant increase in reactive oxygen species, while cold stress initially increased and then decreased reactive oxygen species. Key elements such as superoxide dismutase and nitric oxide increased under heat stress, while proline and heat shock transcriptional factor increased under cold stress. This study provides a basis for understanding the response mechanism of microalgae to temperature stress and improving their tolerance to temperature stress.

Summary: In this study, it was found that a physiologically relevant increase in serum osmolality causes minimal activation of the autophagic response. However, the combined stressors of serum hyperosmolality and mild hyperthermia cause activation of both autophagy and apoptotic signaling. This highlights the importance of considering osmotic status when examining autophagic responses in vivo.

Differential gene expression was observed in P. pyramidalis seeds upon priming, with potential markers identified for water stress tolerance. These findings may contribute to improving seed vigor and stress resilience in plants.

Summary: The interaction within a seed-seedling transition system can directly impact early plant development, including interactions between seed-seed, seed-seedling, and seedling-seedling. Factors such as water dynamics in seed germination, information entropy, and intraspecific communication may all play a role in determining embryo growth during germination.

Summary: The study found that the physiological quality of peanut seeds is predominantly acquired during the development process, reaching its peak between 57 and 76 days after flowering in the late stage of maturation. Additionally, the appropriate proportion of rainfall and thermal sum in the maternal environment were factors that facilitated the acquisition of peanut seed longevity.

Summary: Osmo-priming treatment leads to faster and more uniform germination, but it reduces seed longevity. The decreased expression of stress-responsive transcripts during the treatment results in the shortened life span of osmo-primed tomato seeds. This information can be used to develop markers for monitoring longevity in such seeds.

Summary: The color of the seed coat in Bowdichia virgilioides greatly influences water permeability, with yellowish or orange/reddish seeds being less permeable, and reddish or rusty red seeds having higher permeability. Seeds with reddish color show greater physiological potential, possibly related to the species' maturation point.
