Summary: A new emerging disease of quinoa, quinoa basal stem rot (QBSR), caused by Fusarium solani, was discovered in Shanxi Province, China. Two groups of isolates were classified based on their morphological characteristics and growth rates. The optimum temperature for both groups was 30℃, and the pathogenicity tests showed that mycelia or conidia caused typical symptoms of QBSR on wounded basal stems of Chenopodium quinoa.

Summary: This study investigated the responses of alfalfa to soil salinity and biosolids fertilizer levels. Results showed that higher soil salinity reduced root development and plant height, while increasing crude protein and decreasing fiber content. Biosolids fertilizer had no significant effect on alfalfa growth and quality parameters.

Summary: In this study, the causal agents and main infection source of saffron corm rot were identified using amplicon sequencing and traditional isolation methods. The microbial diversity in diseased saffron corms and soil was significantly reduced compared to healthy ones. Fusarium, Cadophora, and Fusicolla were found to be closely related to corm rot, while Penicillium and Botrytis were not. Functional gene prediction indicated a relatively high abundance of plant pathogens in the diseased soil. Fusarium oxysporum was identified as the pathogen causing corm rot, and corms other than soils were the main primary infection source.

Summary: Bloodstream infections caused by Acinetobacter baumannii, a multidrug-resistant pathogen, are a severe threat to health and linked to high mortality rates. A study in northwest China found that clone complex 92 (CC92) is the most prevalent subpopulation, indicating the dissemination of a dominant clone. The presence of oxacillinase genes and the AdeABC efflux pump system contribute to the carbapenem resistance observed in these isolates. Understanding the molecular epidemiology and resistance characteristics of A. baumannii is crucial for effective strategies in hospital infection control.

Summary: Blackleg and aerial stem rot of potato caused by soft rot enterobacteria have increased in Hebei Province, China. In this study, bacterial pathogens were identified and characterized in potato plants showing blackleg or aerial stem rot. Pectobacterium atrosepticum, Pectobacterium carotovorum, Pectobacterium brasiliense, and Pectobacterium parmentieri were identified, along with a new species of Pectobacterium polonicum. Isolate BY21311 of P. polonicum showed reduced ability to macerate potato tubers compared to other Pectobacterium species.

Summary: Peach shoot blight (PSB) has caused significant production loss in the peach industry in China. The study identified Phomopsis amygdali as the common causal agent, and also discovered two new pathogens, Phomopsis liquidambaris and Diaporthe eres, that could cause PSB. It was found that Phomopsis liquidambaris and Diaporthe eres might become dominant species in the future, highlighting the importance of developing effective disease control strategies.

Summary: Landslides and debris flows are common in the Zhouqu County in Gansu Province, China, due to river erosion, rainfall, and deforestation. Using remote sensing technology, distinct displacements were observed in the fractured fault zone, with temporal variations primarily influenced by seasonal rainfall.

Summary: In China, Pyrenophora avenicola was identified as a causative agent of Drechslera leaf spot (DLS) in oats, with less virulence compared to Pyrenophora chaetomioides. The study showed that P. avenicola had greater tolerance to high temperature, making it more prevalent in warm, low-altitude areas, which is significant for future control strategies against oat DLS.

Summary: Novel goose astrovirus (NGAstV) is causing gout disease in geese worldwide, resulting in significant economic losses. In China, two genotypic species of GAstV (GAstV-I and GAstV-II) are circulating, with GAstV-II sub-genotype IId being dominant. Genetic diversity analysis revealed characteristic mutations in GAstV-II d strains, as well as variations in newly identified isolates over time. These findings contribute to the understanding of the virus's evolution and can aid in the development of preventive strategies.

Summary: The study identified Colletotrichum fructicola, Colletotrichum siamense, and Colletotrichum nymphaeae as the main pathogens causing strawberry anthracnose, with varying aggressiveness towards different parts of the plant. Sensitivity tests to carbendazim showed different levels of resistance among the isolates of the three species.

Summary: The study identified six Alternaria species associated with watermelon leaf blight in China, with A. tenuissima being the most prevalent. Notably, A. infectoria, A. gaisen, and an unclassified Alternaria species were reported as causal agents of leaf blight on watermelon for the first time globally.
