Summary: Two new Cladosporium species, Cladosporium yunnanensis and C. paris, were discovered on medicinal plant leaves in Yunnan Province, China. The morphology and phylogenetic analysis of these new species were compared with related Cladosporium species, expanding the host diversity of the genus.

Summary: The study focused on the phenolic profile of extracts from black cherry leaves and flowers. Different extraction methods led to variations in extractable content, with a higher amount of phenolic compounds found in the flowers compared to leaves. This work highlights the rich source of phenolic compounds in black cherry leaves and flowers, with potential industrial applications for various compounds.

Summary: In this study, a novel species of Alternaria pogostemonis was isolated and identified as the cause of leaf spot disease in Pogostemon cablin. The pathogenicity of A. pogostemonis was verified, and this is the first report of leaf spot disease in P. cablin caused by the Alternaria species. This study contributes to the knowledge of leaf spot diseases in P. cablin.

Summary: Blackberry is the fourth most economically important berry crop, and its production is expanding in the southeastern United States. A study at the University of Florida identified a fungus, Pseudocercospora pancratii, as the causal agent of leaf spots on blackberry. No complete resistance was found among eight cultivars tested, but 'Osage' was the least susceptible and 'Kiowa' was the most susceptible. This study provides important information for disease management and future research for blackberry growers in Florida.

Summary: In this study, three new species of Diaporthe on Acer palmatum were described and their phylogenetic relationships were determined. The tests of Koch's postulates confirmed that these three new species were pathogens causing leaf blight on A. palmatum. This study provides important information on the morphology and phylogenetic relationships of Diaporthe spp.

Summary: In this study, a pathogenic fungus named Pseudopithomyces maydicus was identified as the causal agent of leaf spots on strawberries in China for the first time. The fungus was discovered during a survey in a strawberry field in Guangdong province, and its identification was confirmed through morphological and molecular phylogenetic analysis.

Summary: Bacterial canker of cherry is a worldwide problem for stone fruit production, including in New Zealand. Six pathovars of the bacterium Pseudomonas syringae have been identified as the cause of bacterial canker on Prunus species, with Pss, Psm1, and P. s. pv. persicae being the pathogens of Prunus species in New Zealand. The disease causes extensive canker development and gummosis on sweet cherry, leading to tree decline and significant losses in young orchards.

Summary: The study identified seven Fusarium species associated with leaf spots on mango in China, including some reported for the first time globally. These isolates were found to be capable of causing leaf spot symptoms on artificially wounded leaves. This research contributes to the understanding of Fusarium species as potential causal agents of mango leaf spots.

Summary: This study aimed to investigate the effects of different herbicides on the morphological features of inflorescences and flowers of the North American Prunus serotina in Polish forests. Significant differences in the studied features were found between trees treated with different herbicides, suggesting the effectiveness of using various herbicides to control this invasive species.

Summary: Circular and irregular leaf spots on globe artichoke were observed in the Mediterranean region of Turkiye. Fungal colonies isolated from the leaf spots belonged to Cladosporium cladosporioides and Cladosporium pseudocladosporioides, based on morphological and molecular data. Pathogenicity tests confirmed the association of these fungi with the leaf spots.

Summary: The genome sequences of three bacterial pathogens causing foliar spots on coffee plants show genetic diversity and variability, with Pch having the highest number of exclusive proteins. Pcg strain has the most stable genome, while Pch strain has the most plastic genome. Compared to other Pseudomonas species, Pcg and Pat have more conserved hrp/hrc gene sequences than Pch, which also has the smallest T3SS and largest apoplastic effector repertoires. The common T3SS effector family among the three pathogens is AvrE, indicating its crucial role in pathogenicity towards coffee plants.
