Summary: The study screened two potato cultivars, BARI-401 and Spunta, for their tolerance to simulated salinity and drought through in vitro LiCl and mannitol exposure. Results showed that Spunta was able to better maintain shoot length and had higher antioxidant capacity compared to BARI-401 under high LiCl and mannitol concentrations, indicating its greater tolerance to salinity and drought stress. Further field experiments are needed to confirm these findings.

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: 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: More and more literature data show the health benefits of potato juice, but it is not clear which compounds in potato juice are biologically active. This study aimed to determine the antiproliferative effect of digested potato juice and its processing products. The results showed that glycoalkaloids exhibited cytotoxicity against all cell lines studied, while phenolic acids did not show cytotoxicity. There was a correlation between cytotoxic potency and glycoalkaloids content in all potato juice products.

Summary: Andean potatoes are a good source of dietary antioxidant polyphenols, with skin extracts being more cytotoxic than flesh extracts. We investigated the composition and cytotoxic activity of total extracts and fractions from the skin and flesh tubers of three Andean potato cultivars. Results showed that the aqueous fractions were more cytotoxic than the total extracts, and a combination of both fractions showed a similar cytotoxic response to the corresponding extract.

Summary: Potato is the third most consumed crop globally, but its production is susceptible to yield loss due to increasing drought severity. While root depth is considered the main factor affecting potato drought susceptibility, this review highlights the importance of genotype type, developmental stage, and duration and severity of drought stress. The study provides insight into potato's varying response to drought and suggests improving agronomic practices to mitigate drought stress.

Summary: This study presents a reliable and efficient method for eradicating viruses in potatoes, which is more effective than current methods. Through testing various treatments, the combination of chemotherapy and cryotherapy, or consecutive chemotherapy, combined chemotherapy and thermotherapy, followed by cryotherapy, showed the best results in virus eradication. This improved method has the potential to produce virus-free planting material for the potato industry and facilitate the exchange of virus-free germplasm globally.

Summary: The article discusses the influence of caffeic acid (CA), its mix with chitosan (Chit + CA), and chitosan-based conjugate (Chit-CA) on the growth and proline content of microclone potato plants. Under optimal conditions, CA and Chit-CA promote the growth and development of the plants and increase proline accumulation. Under osmotic stress, CA and Chit-CA enhance the resistance of the plants and maintain their active growth. However, the mechanical mix of Chit + CA inhibits plant growth and development, accompanied by increased proline accumulation, especially under stress.

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: 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: This study supports the idea that apple replant disease (ARD) is local and does not spread into surrounding soil, as only the roots in ARD soil were affected in terms of growth, phytoalexin biosynthetic gene expression, phytoalexin production, and altered microbiome structure. The disturbed soil microbiome enriched with low mobility of the ARD-causing agents induces a strong plant defense and rhizoplane microbiome dysbiosis, concurring with root damage.

Summary: This study found a significant correlation between the visual scoring and apoplastic liquid volume of hyperhydricity in apple and Arabidopsis thaliana. By analyzing the leaf reflectance spectra, specific absorption peaks at 980 nm, 1150 nm, 1400 nm, 1520 nm, 1780 nm, and 1930 nm were identified. A machine learning model, support vector machine, showed the highest accuracy of 85% in classification of hyperhydric explants. This research provides an approach to automatically detect hyperhydricity by identifying key spectral features.

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 study suggests that Tagetes can alleviate apple replant disease by altering the nematode community in the soil. Nematodes extracted from soil treated with Tagetes had less impact on plant growth compared to those extracted from grass-treated soil. This indicates the potential of using Tagetes as a control option for managing apple replant disease.
