Summary: TaPYL5, a member of the ABR family in wheat, acts as a mediator of drought stress adaptation in plants by forming an ABA core signaling module with TaPP2C53 and TaSnRK2.1. TaPYL5 significantly alters the transcription of genes involved in biological processes related to drought defense, making it a valuable target for engineering drought-tolerant wheat cultivars.

Summary: This study investigates the molecular mechanisms involved in seed germination under short episodes of heat stress during the wheat grain filling stage. The expression levels of genes related to ABA, GA, and ETH were found to be significantly different under heat stress conditions. The study also highlights the role of temperature in regulating seed germination, with temperatures above 28 degrees Celsius repressing ABA-related gene expression and promoting germination.

Summary: Drought stress can significantly reduce wheat growth and development as well as grain yield. This study investigated the morpho-physiological and hormonal responses of six winter wheat varieties to drought stress during stem elongation and anthesis stages and measured grain yield-related traits after harvest. The results showed that some varieties were more tolerant to drought while others were more sensitive.

Summary: This study found that abscisic acid (ABA) plays a significant role in mediating the response of stomata to elevated CO2 and drought. Elevated CO2 promotes ABA accumulation and regulates the expression of ABA biosynthetic and metabolic genes, enhancing drought tolerance in plants. In the ABA mutant flacca, ethylene functions as a compensatory role in inducing stomatal closure during soil drying.

Summary: Drought priming increases drought tolerance in wheat by up-regulating genes related to ABA and JA signaling pathways. The interplay between ABA and JA is essential for priming-induced drought tolerance, with JA acting upstream of ABA. Inhibitors of ABA and JA biosynthesis affect plant responses to drought stress under priming conditions.

Summary: GlcAK gene plays an important role in plants by converting glucuronic acid into UDP-glucuronic acid for cell wall biomass synthesis. Overexpression of GlcAK gene in Arabidopsis thaliana results in decreased contents of ascorbic acid and phytic acid, but increased root length and enhanced seed germination under abiotic stress conditions.

Summary: The highly conserved Sal1 gene has been edited in hexaploid wheat using precise gene editing techniques. The resulting mutant wheat plants with disabled Sal1 genes exhibit slower growth under drought conditions and slower senescence under water limiting conditions. The use of multiplexed gRNAs enabled effective targeted gene editing of the Sal1 gene family.

Summary: This study reveals that the Puccinia striiformis f. sp. tritici (Pst) effector Pst21674 suppresses host immunity in wheat by targeting the abscisic acid-, stress-, and ripening-induced protein TaASR3. Pst21674 interferes with the polymerization of TaASR3 and inhibits the transcriptional activation of defense-related genes, leading to reduced wheat resistance to stripe rust.

Summary: The study demonstrated that both melatonin (MT) and nitric oxide (NO) can alleviate the growth inhibition of soybean caused by drought stress, by enhancing plant biomass, photosynthesis efficiency, and water content, while reducing reactive oxygen species accumulation. The treatments with MT and NO also increased antioxidant enzyme activities, reduced lipid peroxidation, and regulated the synthesis of the plant hormone abscisic acid (ABA) during drought stress. Moreover, the study found that the combination of MT and NO led to improved drought stress tolerance in soybean by triggering the downregulation of NO accumulation and increasing the expression of transcription factors.

Summary: Terminal heat stress is a major obstacle for wheat production in South Asia. This study aimed to identify heat-tolerant wheat genotypes and determine an easy phenotyping trait for this purpose. A cross was made between two popular cultivars, one with heat tolerance and the other with high-yielding but susceptible to terminal heat stress. 167 recombinant inbred lines (RILs) were tested in different environments, and normalized difference vegetation index (NDVI_AH) and grain filling duration (GFD) were found to be significant traits for genotype, environment, and genotype x environment interaction. Correlation analysis showed that NDVI_AH had a significant association with grain yield (GY) in most environments. The study suggests that NDVI_AH and GFD are important traits for breeding wheat varieties with terminal heat stress tolerance.

Summary: In this study, QTL mapping for dorsal aleurone thickness (DAT) in rice was conducted using chromosome segment substitution lines. Three QTLs, qDAT3.1, qDAT3.2, and qDAT7.1, were identified and validated in multiple environments. Increasing the thickness of the aleurone layer is a practical approach to develop highly nutritious cereals, and identifying genes associated with aleurone thickness is important for improving the nutritional and health values of rice.

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.
