Summary: Heat stress is a major limiting factor for rice production, and understanding the molecular mechanisms of rice's response to heat stress is crucial. This study discovered a novel heat-stress-responsive strategy in rice that regulates ROS homeostasis through the immune activator OsEDS1. OsEDS1 promotes ROS clearance by stimulating catalase activity, and loss or overexpression of OsEDS1 affects rice heat tolerance. The findings provide insights into heat stress responses in rice and offer a theoretical basis and genetic resources for breeding heat-tolerant rice varieties.

Summary: Cellular function is mainly differentiated through membrane-bound organelles, but recent research has shown that membraneless structures formed through phase separation can also achieve compartmentalization in liquid droplet-like properties. Arsenite-induced cytoplasmic stress granules play a significant role in protein homeostasis by regulating translation, with the catalytic subunit Glc7 of protein phosphatase-1 being involved in their formation. This stress-induced granule is highly specific to arsenite and controls translation through a new mode of translational control by Glc7, independently of its established role in regulating eIF2 alpha.

Summary: Global climate change has a significant impact on plant growth and reduces crop productivity worldwide. Rice, as a vital food crop, is vulnerable to high-temperature stress from its early growth to reproductive stages. This review summarizes recent advancements in understanding the molecular mechanisms of heat stress responses in rice, including heat sensing and signaling, transcriptional regulation, transcript processing, protein translation, and post-translational regulation. The irreversible effects of high temperature on rice reproduction and grain quality are also highlighted. Challenges and opportunities for future research in this area are discussed.

Summary: Disordered plant chaperones are crucial for plants to survive in harsh conditions, with dehydrins being one of the largest groups of disordered chaperones expressed under various abiotic stress conditions. Despite their importance, the exact role and relevance of the conserved regions in dehydrins have not been formally addressed. Research on the intrinsically disordered stress protein ERD14 in A. thaliana shows that different conserved segments, whether directly involved in partner binding or not, are equally necessary for proper function, highlighting the importance of balanced interplay between different regions for cellular protection.

Summary: This study conducted a genome-wide investigation of the CsPP2C gene family in cucumber and identified 56 CsPP2C genes. Phylogenetic analysis revealed the classification of PP2C genes in cucumber and Arabidopsis into 13 groups. Different expression patterns of CsPP2C genes were observed under various abiotic treatments, and specific tissue expression patterns were also observed. Segmental duplication events played a key role in the expansion of the PP2C gene family in cucumber. Moreover, the presence of ABA and drought response elements in the promoter region of CsPP2C genes was detected. These findings provide a reference for the identification of the PP2C gene family in other species and lay the foundation for future studies on the function of PP2C genes in cucumber.

Summary: This study identifies STAMBPL1 as a deubiquitinase of MKP-1 in breast cancer cells, which stabilizes MKP-1 protein by deubiquitination. Depletion of STAMBPL1 and MKP-1 increases breast cancer sensitivity to cisplatin and activates the JNK signaling pathway. These findings suggest that the STAMBPL1/MKP-1 axis could be a potential therapeutic target in breast cancer.

Summary: The study highlights the vulnerability of the 880 million agricultural workers globally to heat stress caused by climate change, affecting labor productivity. Limiting global warming to 1.5 degrees Celsius can prevent a significant reduction in labor capacity, particularly in countries like Indonesia, the Philippines, Bangladesh, and certain Indian states. This research underscores the importance of considering regional disparities and seasonal differences in estimating the impact of climate change on labor productivity and heat stress in agricultural workers.

Summary: Increased heat stress during cropping season has significant negative effects on rice yield and quality. This study conducted a meta-analysis using a combined dataset from published literature to investigate the impacts of high daytime temperature (HDT) and high nighttime temperatures (HNT) on rice yield and its components, as well as grain quality traits. Results showed that HNT had a more detrimental impact than HDT, with seed set rate being the most sensitive trait to temperature increase. Both HDT and HNT affected grain quality, including increasing chalkiness and decreasing head rice percentage. The study fills knowledge gaps on rice yield losses and highlights the importance of considering impacts on rice quality for breeding high-temperature tolerant rice varieties.

Summary: Vascular barrier dysfunction, characterized by increased permeability and inflammation of endothelial cells, plays a crucial role in acute lung injury, ARDS, sepsis, and COVID-19. Ser/Thr protein phosphatases (PPases), including PP1 and PP2A, are important regulators of endothelial barrier integrity and cytoskeletal remodeling. Understanding the role of PPases in EC barrier regulation can provide insights into the development of therapeutic strategies for these lung diseases.

Summary: The study found that rice rapidly induces jasmonate signaling upon application of acetic acid, leading to physiological changes similar to those seen under drought conditions. The major metabolite of exogenously applied acetic acid in xylem sap was determined to be glutamine, and the expression of drought-responsive genes in shoots was attenuated by acetic acid treatment. These data suggest that acetic acid activates root-to-shoot jasmonate signals that partially overlap with those induced by drought, providing an acclimated state for shoots before subsequent drought conditions.

Summary: Eukaryotic cells contain proteinaceous condensates formed by phase separation, which have the potential for bioengineering and synthetic biology. This study identifies an atypical jasmonate signaling regulator, JAZ2, that forms large condensates in both the nucleus and cytosol of rice cells. These JAZ2 condensates can be gel-like, solid, or liquid-like, and their formation is driven by intermolecular interactions of JAZ2 molecules. The findings suggest the possibility of using JAZ2 condensates to construct artificial membraneless organelles in plant cells.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

Summary: This study identified the high nitrogen use efficiency (NUE) black sesame variety 17-156 and analyzed its underlying physiological and molecular mechanisms. The results showed that 17-156 possesses a sophisticated nitrogen metabolizing machinery to uptake and assimilate higher quantities of inorganic nitrogen, simultaneously improving carbon metabolism and growth. Many important genes were up-regulated in 17-156 under high nitrogen condition. Additionally, 38 potential candidate genes were identified for future studies to improve sesame's NUE. These findings provide valuable resources for understanding the regulatory network of nitrogen metabolism and developing sesame cultivars with improved NUE.

Summary: Selenium (Se) can reduce uptake and translocation of cadmium (Cd) in plants by regulating root morphology. This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
