Summary: In this study, 144 tetraploid potato genotypes were evaluated to investigate the variation of physiological and agronomic traits under control and water stress conditions. A total of 18 SNP markers significantly associated with these traits were identified, providing insights into the mechanisms of potato tolerance to water stress and potential markers for marker-assisted selection programs.

Summary: Potato is a widely grown crop that can adapt to various geographies and climates. Pigmented potato tubers contain large amounts of flavonoids, which have functional roles and act as antioxidants in the human diet. The effect of altitude on the biosynthesis and accumulation of flavonoids in potato tubers is poorly understood.

Summary: Rice production is the biggest contributor to plant-based carbon emissions globally, particularly in Asia. Introducing sustainable intensification practices or diversifying with lower-emission crops like potatoes is crucial for mitigating climate change. This study analyzed the impact of potato cultivation under zero/minimum-tillage and/or organic mulching on key performance indicators in Asia. The results showed that potato cultivation under these conditions can increase yield, profitability, nutrient-use efficiency, and water productivity, thanks to significant soil moisture conservation.

Summary: Potato is an important non-grain food crop, and increasing its yield potential can be achieved by addressing bottlenecks in photosynthetic metabolism. Through simulating and optimizing resource investment, it was found that increasing the amounts of three enzymes - Rubisco, FBP aldolase, and SBPase - can enhance the photosynthetic rate of potato.

Summary: Proper irrigation and fertilization are crucial for achieving high yield and quality in potato production. This study investigated the impact of irrigation and nitrogen fertilization on potato yield, quality, and water use efficiency. Results showed that irrigation had a greater influence on potato yield and growth than nitrogen levels. Full irrigation with 300 kg N ha(-1) resulted in the highest total tuber yield, while low irrigation treatments led to significantly lower yields. However, the 66% field capacity irrigation treatment consistently had the highest water use efficiency.

Summary: In this study, a highly-efficient anther culture system of tetraploid potatoes was established. The ideal hormone combination for anther callus induction was determined, and a promotive induction effect on anther callus was achieved using a specific medium. Through this system, 201 anther culture plantlets were differentiated and various ploidy levels were obtained, providing important guidance for potato ploidy breeding.

Summary: Decisions in irrigation management can significantly impact potato production sustainability. A study evaluating different irrigation regimes on three russet potato varieties found that over-irrigation at 125%ET was not beneficial, while deficit irrigation at 75%ET during late tuber bulking and maturation stages could result in more sustainable water use.

Summary: The periderm of potato is a significant corky tissue that plays a crucial role in protecting the tuber from pathogens and water loss. Its formation is closely linked to the development and physiological disorders of potato, such as skin injuries and russeting.

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 investigated the use of a mixture of lytic bacteriophages to protect potatoes from the pathogenic bacteria, Dickeya solani. Laboratory and field experiments showed that the phage treatment significantly reduced soft rot symptoms and improved leaf cover and tuber yield. The findings suggest that the phage mixture has the potential to effectively protect potatoes from D. solani infection.

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: 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: This study assessed the susceptibility of commercial potato cultivars to the root lesion nematode Pratylenchus penetrans. The results showed that the cultivar Laura had a lower susceptibility index, indicating stronger resistance to the nematode, while cultivars Camel and Picasso had higher susceptibility indices. There were variations in the susceptibility of potato cultivars to the nematode, but there were no significant differences in the number or weight of tubers produced by infected and non-infected plants.

Summary: This study identified two potato transcription factors as regulators of wound-induced suberin biosynthesis and deposition, providing evidence for the genetic basis of differential wound suberization capacities in different potato cultivars. The results suggest that export of suberin from the cytosol to the apoplast and ligno-suberin deposition may be limiting factors for wound suberization, and that StMYB74 and StMYB102 play important roles in the process. Polymorphisms in StMYB102 may also influence cultivar-specific wound suberization capacity, offering potential insights for targeted breeding approaches to improve potato tuber storage life.

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.
