Summary: Potato virus Y (PVY) is an important viral pathogen of potato with genetic variants and geographic distributions influenced by environmental factors, aphid vectors, and reservoir plants. In this study, we used high-throughput sequencing to investigate PVY populations transmitted to potato plants by aphids in different climate zones of Russia. We found significant differences in PVY diversity between regions, suggesting the impact of environmental factors on PVY genetics.

Summary: The interaction between plants and viruses is influenced by environmental factors such as temperature. In this study, the researchers investigated the gene expression changes in potato plants infected with potato virus Y (PVY) under normal and elevated temperature conditions. They found that the combined PVY and heat stress treatments caused significant changes in gene expression, affecting both protein-coding and non-coding RNAs. The researchers also discovered new genes involved in polyamine formation and poly ADP-ribosylation, as well as novel non-coding RNAs with miRNA binding sites. The findings provide insights into the functional links between virus infections and transcriptome reprogramming, RNA methylation, and alternative splicing.

Summary: The interaction between plants and viruses is greatly affected by environmental factors such as temperature, with higher temperatures increasing plant susceptibility to virus infections. One of the key mechanisms involved in this regulation is the down-regulation of enzymes in the methionine cycle at elevated temperatures. Treatment with methionine can restore metabolite levels and reduce susceptibility to viruses at higher temperatures.

Summary: This study identified C5-MTases and DeMets in potatoes through genome-wide analysis and investigated their expression patterns under high temperature. It was found that CMT and DRM genes were significantly upregulated in the heat-tolerant genotype under high temperature, and demethylases also showed strong upregulation in the heat-tolerant genotype. Furthermore, high temperature affected the expression of various genes involved in the tuberization process, possibly through active DNA demethylation and RNA-directed DNA methylation pathways.

Summary: Increased temperatures caused by climate change pose a significant threat to agriculture and food security. This study characterized the responses of six tomato varieties to high temperatures and found significant variations in their heat stress tolerance. The results suggest that plants may employ different mechanisms to overcome heat stress, and understanding these molecular events could help in selecting climate resilient tomato varieties.

Summary: The reactions of three Polish potato cultivars to potato virus S (PVS) were studied, revealing that Tajfun and Tonacja cultivars exhibited partial resistance while Bryza cultivar was susceptible. Different symptoms were observed in both resistant and susceptible genotypes, and delayed systemic infection was observed in some cases. The study also found variations in the expression of resistance-related miRNAs and mRNA targets among different cultivars.

Summary: This study used GC-MS to analyze the leaf metabolomes of potato cultivars Premier Russet and Russet Burbank following inoculation with different strains of PVY. Common and strain-specific metabolites induced by PVY inoculation were identified. The regulation of carbohydrate metabolism was found to be relevant for defense against PVY.

Summary: Potato is an important food crop that is rich in starch, proteins, antioxidants, and vitamins. However, it is negatively affected by temperature rise. In this study, 26 StJMJ proteins were identified in potato, and they were classified into five different classes. Gene expression analysis showed that the StJMJ genes are heat-inducible and play an important role in modulating heat tolerance in potato.

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: 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: 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: Potato virus Y (PVY) is a economically important virus infecting potatoes worldwide, transmitted from infected to noninfected plants by aphids. Current-season infection of PVY may decrease yield and tuber specific gravity for some chip processing potatoes, but does not affect the appearance of chips.

Summary: Plant-virus interactions can be influenced by elevated temperature, affecting susceptibility to viruses. The Gala potato cultivar shows temperature-independent resistance to PVY by upregulating major enzymes associated with the methionine cycle, while the Chicago cultivar's susceptibility to PVY is linked to reduced levels of S-adenosyl methionine at high temperatures.

Summary: In this study, we developed a spray-induced gene silencing (SIGS)-based approach for delivering dsRNA to protect potato against PVY infection. We found that exogenously applied PVY dsRNA activated both RNAi and PTI defense pathways and affected the accumulation of PVY and PVX viruses. In addition, PVY-specific dsRNA upregulated the production of a key enzyme involved in poly(ADP-ribose) metabolism. These findings provide insights for future development of innovative approaches for crop protection.

Summary: The nucleolus and Cajal bodies regulate host defences against pathogen attack by interacting with PARP1 and increasing SA concentrations, leading to activation of SA-responsive gene expression and restriction of TRV infection. SA treatment can counteract the negative effect of PARP inhibitor 3AB on plant recovery from TRV infection. PARP1 plays a key role in the regulatory network integrating coilin activities as a stress sensor for virus infection and SA-mediated antivirus defence.
