Summary: Due to climate change, water availability has become a major limiting factor in potato production. This study analyzed the differential response of physiological and yield components in six potato varieties under water deficit conditions and found that Monalisa showed the best response in tuber production under stress conditions. Indirect selection based on parameters associated with water stress can be a useful tool in potato breeding programs for the identification of more tolerant varieties.

Summary: Salinity stress significantly reduces plant height, stem numbers, and tuber yield in potato varieties. Salt-tolerant genotypes exhibit better performance under salt stress due to a strong antioxidant defense system and osmotic adjustment, suggesting their potential for breeding new high-yielding, salt-tolerant lines. Specific physiological and biochemical traits were identified as predominant for tuber yield under salt stress, providing insights for further genetic and molecular studies on salt tolerance in potato.

Summary: In the face of climate change-induced heat and drought stress, the physiological, biochemical, and molecular responses of potatoes have undergone changes that ultimately affect tuber production and yield. Therefore, it is necessary to comprehensively screen germplasm and apply appropriate methods and strategies to cultivate potato cultivars that can thrive in drought-affected and heat-prone areas.

Summary: This study demonstrates that stu-miR827 is involved in regulating the drought tolerance of potato by controlling the stomatal density. Suppression of stu-miR827 leads to higher stomatal density and weaker drought resistance in transgenic potato lines. StWRKY48 is identified as the target gene of stu-miR827 and its expression is induced by drought stress. The results suggest that suppression of stu-miR827 may negatively regulate the drought adaptation of potato by increasing stomatal density.

Summary: In this study, the gene expression differences between control and water-stressed potato plants were analyzed using RNAseq. The variety Agria showed a better stress response compared to Zorba, with more differentially expressed genes (DEGs) detected. The most highly expressed gene under drought conditions was Abscisic acid and environmental stress-inducible protein TAS14-like. Several metabolic pathways and cellular components were found to be affected by water stress, providing valuable information for breeding more tolerant potato varieties.

Summary: Drought stress is a significant problem for potato production, especially with climate change and temperature peaks along with drought periods. This study aimed to analyze eight genes and determine their suitability for detecting early drought stress in potato. Six potato genotypes were examined for plant growth and physiological parameters after seven and 14 days of stress. Changes in gene expression were observed after seven days of stress for three genes: INH1, POD, and SBT1.7. The INH1 gene showed consistent upregulation in all genotypes and may be a suitable candidate for detecting drought stress in potato.

Summary: The increasing human population and changing climate have led to frequent drought spells, posing a serious threat to global food security. Identifying high yielding drought tolerant genotypes is an effective approach to combat these challenges. Through a field experiment, it was found that drought stress reduced the growth of wheat genotypes, with BAW 1169 showing the best adaptation and potential for future breeding programs.

Summary: In this study, 37 StSOS1 genes were identified and found to be unevenly distributed across 10 chromosomes in potato, with most of them located on the plasma membrane. These genes contain abundant cis-elements involved in various abiotic stress responses. Tissue specific expression showed that 21 of the 37 StSOS1 genes were widely expressed in various tissues or organs of the potato. Molecular interaction network analysis suggests that these genes may interact with other proteins involved in potassium ion transmembrane transport, response to salt stress, and cellular processes. Collinearity analysis showed orthologous StSOS1 genes in tomato, pepper, tobacco, and Arabidopsis. Moreover, the expression of StSOS1 genes were significantly modulated by various abiotic stresses, especially salt and abscisic acid stress. Subcellular localization in Nicotiana benthamiana suggested that StSOS1-13 was located on the plasma membrane. These results provide a comprehensive overview of the StSOS1 gene family and pave the way for further analysis of their function in SOS and hormone signaling pathways.

Summary: PAHs are environmental pollutants generated by incomplete combustion of organic matter, which can induce their own metabolism by activating AHR and CAR. Most PAHs activate AHR, while non-carcinogenic PAHs tend to activate CAR, leading to the expression of respective target genes. Additionally, an increased PAH ring number is associated with AHR activation and DNA double-strand breaks, while smaller PAHs activate CAR but do not cause DNA damage.

Summary: Hyperspectral imaging is a useful tool for non-destructive phenotyping of plant physiological traits, especially for studying responses to drought, development, and day-night cycles. With better understanding of spectral measurements, it has been demonstrated to accurately predict physiological changes in plants under different conditions using advanced processing techniques such as partial least squares regression.

Summary: The study identified genomic regions and candidate genes of major interest for drought tolerance in cultivated potatoes, as well as QTL and genes related to starch synthesis and metabolism. Overlaps of DRYM QTL with metabolite QTLs suggest possible trade-offs between starch and compatible solute biosynthesis. Mutations in genes under drought tolerance QTL on linkage group 3 were identified using BSAseq technology.

Summary: The study analyzed hepatic zonation in mouse liver using mass spectrometry and DigiWest technique, providing insights into the differences in protein expression between periportal and perivenous hepatocytes. New zonated proteins identified included kinases and phosphatases related to growth factor-dependent signaling, as well as a large panel of cytochrome P450 enzymes mainly localized in the perivenous region. The data revealed key regulators and pathways preferentially active in either periportal or perivenous hepatocytes, with beta-catenin signaling and nuclear xeno-sensing receptors being prominent perivenous regulators, and kinase- and G-protein-dependent signaling cascades predominantly active in periportal hepatocytes.

Summary: This study used a mouse model with humanized livers to investigate the effects of the model CAR activator phenobarbital (PB) on human and mouse hepatocytes. The proteomic analysis showed similar responses in nuclear receptor activation and xenobiotic metabolism between human and mouse hepatocytes. However, activation of the MYC proliferation regulator was only predicted in mouse hepatocytes, not in human hepatocytes. This study provides comprehensive proteomic evidence that PB induces adaptive metabolic responses but not hepatocellular proliferation in human hepatocytes in vivo.

Summary: In this study, the authors developed a strategy for studying plant traits directly in the field, bypassing the translation step from lab experiments. They found that gene expression in autumn can predict yield traits in spring for rapeseed plants. The top predictor genes are involved in developmental processes that occur in autumn, indicating the influence of autumnal development on crop yield.
