Summary: This study analyzed the volatile organic compounds (VOCs) emitted by different potato cultivars with varying resistance to late blight disease. The results showed that cultivars with higher resistance had higher emissions of VOCs, particularly sesquiterpenes and monoterpenes. The VOC profiles could be used as an indicator to identify potato cultivars resistant to late blight disease.

Summary: By monitoring meteorological and aerobiological data, machine learning algorithms such as random forest and decision tree successfully predicted the concentration of Phytophthora infestans sporangia, with model accuracies of 87% and 85% respectively. Including this type of information in forecasting systems can improve the accurate estimation of potato late blight pathogen sporangia.

Summary: This study evaluated the resistance of nine potato cultivars against early blight using a Decision Support System in a potato-producing area in Northwest Spain. The research found that the susceptibility of potato cultivars was influenced by weather conditions and disease severity, and the use of alternative pest management strategies such as DSS can improve potato yields while maintaining environmental sustainability.

Summary: A study conducted at ACI Limited developed a late blight resistant potato clone, C2-5, by using BARI Alu 77 as the female parent and BARI Alu 53 as the male parent. This clone showed resistance to foliage destruction and exhibited high tuber yield potential. It also tested positive for several late blight resistance genes/QTLs. This new clone can be considered a potential candidate for cultivation and further breeding programs.

Summary: The genetic architectures of potato vine and skin maturity were investigated, and their correlation was examined in this study. It was found that the vine maturity trait was influenced by the CDF1 gene, while the skin maturity trait had minor QTLs. Through whole-genome sequencing, the statistical alleles from QTL models were successfully connected with biological alleles, which represents a new milestone in genomics-assisted breeding for tetraploid species.

Summary: Late blight caused by Phytophthora infestans is a major disease for tomato and potato production worldwide. This study characterized the P. infestans populations in Thailand using various techniques and found that tomato isolates are from the same lineage as those from 1994 to 2002, while potato populations have changed. The different responses to fungicides can be attributed to the use of metalaxyl, host preferences, and migration of new genotypes from infected potato seeds.

Summary: A study conducted in Danish potato fields found that isolates of P. infestans had developed resistance to mandipropamid, with a dominance of the EU43 genotype. Field experiments confirmed the resistance of EU43 isolates to mandipropamid. This is the first report of mandipropamid resistance in P. infestans.

Summary: This study aimed to evaluate the reaction of eight cultivars and five advanced clones to late blight under field conditions, and found that some of the varieties showed resistance to Phytophthora infestans. BRS Clara and Markies showed the greatest variations, being susceptible in the autumn of 2018 experiment and moderately resistant in the autumn of 2019 experiment.

Summary: In recent years, early blight epidemics have been causing significant yield losses in potato crops. Decision support systems are currently lacking for farmers to manage early blight. Based on research, plant-based forecasting models offer the best predictions for the first symptoms of early blight.

Summary: A study revealed that an old strain of Phytophthora infestans, known as A1, has been present in Australia for approximately 110 years, and has caused multiple outbreaks in the past century. Furthermore, the comparison of infected potatoes from Victoria, South Australia, and Tasmania confirmed the presence of an old strain in Australia. This study highlights the importance of potato biosecurity and ongoing surveillance in preventing the spread of more aggressive strains of the pathogen.

Summary: This study focuses on the genetic factors of barley maturity in low temperature and long photoperiod conditions. Through controlled cultivation and research on 84 spring barley lines, it identified genetic factors related to early maturity and height stability. The insights gained from this study will enhance our ability to adapt barley and other cereals to northern climates.

Summary: Genome-Wide Association Studies identified novel resistance QTL for barley scald in four MAGIC populations, with candidate genes involved in pathogen defense. Introducing resistance to multiple diseases in Nordic barley populations has led to the distribution of lines with high resistance levels among plant breeders for development of disease-resistant cultivars.

Summary: This study validated boscalid resistance in a Swedish population of A. solani, both in the field and laboratory, and identified mutations associated with reduced sensitivity. It was found that the efficacy of boscalid against early blight significantly decreased over the years, suggesting that early blight management in southeast Sweden should no longer rely on boscalid.

Summary: Through whole-genome sequencing of 48 isolates of Alternaria solani from potato fields across Europe, seven genotypes were identified which do not follow a geographical pattern but are spread throughout Europe. Evidence of recombination on the genome indicates higher adaptive potential of the fungus than previously thought. The Sdh mutations associated with SDHI resistance appeared independently multiple times in different genetic backgrounds.

Summary: Through resequencing four genes, it was found that Icelandic barley genotypes with extreme earliness are correlated with specific winter-type alleles in certain genes, with one haplotype combination potentially resulting in extreme earliness but severe yield penalties, while another combination showed a combination of earliness and high yield.

Summary: Potato early blight, caused by the necrotrophic fungus Alternaria solani, can lead to yield losses of up to 50% if left uncontrolled. Current control strategies using chemical fungicides are not sustainable due to rapid development of fungicide resistance. Lack of understanding of potato defences and resistance mechanisms hinders the development of more sustainable control methods.

Summary: This study used genotyping-by-sequencing to investigate the diversity, population relationships, and phylogeographic structure of Elymus mutabilis and Elymus transbaicalensis. The results revealed that E. mutabilis and E. transbaicalensis can be distinguished as two distinct species without genetic introgression. The phylogeographic structure aligned with the geographical distribution of the species, with populations from northern Europe, southern Siberia, and far east Russia forming a separate clade separated from peripheral populations in central Asia.

Summary: In this study, three genotypes of quinoa with different seed protein content were characterized using nutrient and transcriptome analyses. Genotype differences in gene expression and genetic polymorphisms associated with increased protein content were identified. The findings contribute to a better understanding of the genetic regulation of seed quality traits in quinoa and suggest potential markers for improving seed quality.

Summary: This article examines the effectiveness of strategies aimed at reducing reliance on synthetic fungicides for early blight control in potatoes. The results show that while biological control agents and plant resistance inducers can greatly reduce infection in greenhouse trials, their efficacy is significantly reduced in field trials, particularly when applied with tractor sprayers.
