Summary: In this study, we investigated the relationship between plant phytotoxicity and glycoalkaloid content in potato leaf extracts. We found that potato progeny with high glycoalkaloid content showed phytotoxicity against mustard, while progeny with low glycoalkaloid content stimulated mustard growth. RNA sequencing analysis revealed that the upregulation of a flavonol synthase/flavonone 3-hydroxylase-like gene in low phytotoxicity progeny stimulated plant growth. These findings suggest that metabolic shifts and specific compositions of glycoalkaloids in potato leaf extracts may be responsible for different physiological responses in mustard.

Summary: This study provides genomics resources for nine non-inbred adapted diploid potato clones. The analysis reveals variations in genome heterozygosity among clones and the presence of deleterious alleles throughout the genome. The study also uncovers a novel variant of a gene related to early tuberization. These genomics resources will be valuable for potato breeding and genome design.

Summary: The study aimed to identify and characterize drought-tolerant potato genotypes and related key traits through assessing tuber yield under greenhouse conditions. It was found that tolerant potato genotypes showed a significant increase in water-use efficiency, and leaf protein content, photosynthesis rate, and transpiration rate were correlated with drought tolerance.

Summary: The main objective of this study was to develop a method to identify and characterize drought-tolerant potato genotypes and the related key traits. Potato genotypes differed in their ability to tolerate drought based on their capacity to maintain percent tuber yield under drought relative to their well-watered controls. The rates of photosynthesis, instantaneous water-use efficiency (WUE), and leaf protein content can be used as the selection criteria for drought-tolerant potato genotypes.

Summary: Potato is the most important non-grain food crop, and tandem duplication plays a significant role in genome evolution. This study used multiple potato genotypes to investigate the abundance and distribution of tandemly duplicated genes, the bias in functional specificities, the relationship among coding sequence, promoter and expression divergences, and the role of tandem duplication in generating lineage-specific gene families. The results showed that tandemly duplicated genes are dispersed throughout the genome and exhibit different functional enrichments. There is a significant correlation among expression, promoter, and protein divergences in tandemly duplicated genes. The lineage-specific expansion of gene families by tandem duplication, coupled with functional bias, has contributed to potato's genotypic diversity and adaptation to environmental stimuli.

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: Potato, a drought-sensitive crop, is facing threats to its global sustainable production due to changes in water availability. This study compared the responses of two Andigenum varieties with contrasting drought tolerance at early and late time points of drought stress exposure. The results showed widespread differences in the response of the two varieties, with the tolerant variety exhibiting faster upregulation of ABA-related genes and stronger cell wall reinforcement and remodeling in both leaves and roots. These findings provide insights into the molecular bases of drought tolerance mechanisms and have implications for improving drought resistance and yield stability in modern potato cultivars.

Summary: The study revealed that CIPK genes in potatoes play significant roles in plant growth, development, and stress tolerance, with StCIPK10 being particularly important in enhancing potato's tolerance to drought and osmotic stress. StCIPK10 acts at the intersection of abscisic acid and stress signaling pathways, controlling root growth and stomatal closure in potatoes, and interacts with various CBL proteins to modulate plant responses to environmental stresses.

Summary: One of the main impacts of drought stress on plants is the excessive accumulation of reactive oxygen species (ROS), which can be highly toxic to cells if not cleared quickly. Superoxide dismutase (SOD) is a crucial antioxidant enzyme that plays the first role in scavenging active oxygen. The miR398s family of miRNAs has been shown to be significant in plants' response to environmental stress. Potato stu-miR398b-3p was found to cleave Cu/Zn SOD mRNA, and overexpression of stu-miR398b-3p led to decreased SOD activity during drought stress.

Summary: Late blight, caused by Phytophthora infestans, is a devastating disease in potato-producing regions. Cultivation of resistant varieties and identification of germplasms with late blight resistance are effective ways to control the disease. A diverse population of 189 genotypes was screened for resistance, revealing broad-spectrum and isolate-specific resistant resources. Genetic analysis found abundant variation, with differentiation among populations and potential for gene improvement in breeding programs. Results provide valuable information for cultivar improvement and resistance gene mining.

Summary: This study compared the physiological responses of two potato cultivars to salt stress and assessed their salt tolerance through principal component analysis. The Na+, K+, and Ca2+ flux of the cultivars under salt stress were recorded, and the expression levels of ion transport-related genes and transcription factors in salt-tolerant cultivars were explored. The results showed that the two cultivars differed in seven physiological indicators of salt tolerance, with 'Longshu 5' being more tolerant than 'Qingshu 9'. Furthermore, ion transport-related genes and transcription factors played a role in improving salt tolerance.

Summary: Hormones play a crucial role in plant disease resistance and defense. This study analyzed transcriptome data of a late blight-resistant potato genotype treated with ethylene, jasmonate, salicylic acid, and Phytophthora infestans to assess the ET/JA/SA regulatory network's role in disease resistance and predict resistant genes. The findings suggest that differentially expressed genes overlapped significantly in all treatments, and specific genes for disease interaction were expressed differently in the CN152 treatment. The study reveals the potential for inducing resistance genes through alternative splicing and highlights the synergistic effect of JA and ET pathways.

Summary: Freezing severely affects potato production. Understanding the pathways and metabolites that regulate potato's freezing tolerance is beneficial for cultivation and breeding purposes. In this study, it was found that Solanum acaule is more freezing tolerant compared to S. tuberosum. Through RNA-seq and metabolomics analysis, it was discovered that S. acaule activated different genes and enriched certain pathways, such as the hormone signaling pathway involving salicylic acid. Further analysis showed that the content of salicylic acid increased in S. acaule after exposure to cold conditions, leading to improved freezing tolerance. Additionally, the application of salicylic acid to potato enhanced freezing tolerance and increased the expression of HSFC1.

Summary: The study found that potato plants adapt to changes in soil water and nitrogen content by altering gene expression and physiological characteristics. Genes related to photosynthetic pigments and oxygen release complex were up-regulated, while genes encoding rate-limiting enzymes in the Calvin-Benson-Bassham cycle were increased. Furthermore, genes related to root nitrogen metabolism were highly expressed, and protein content in the tuber increased. A molecular model of potato responses to alterations in soil water and nitrogen content was constructed.
