Article Synopsis
- A team of over 180 researchers from more than 40 countries is addressing the issues related to "phantom agents," which are proposed pathogenic agents that are listed without concrete evidence of their existence.
- These phantom agents, identified only through symptoms and lacking proper isolates or genetic data, create obstacles for trade and plant certification, making effective detection and risk assessment difficult.
- The researchers recommend removing these agents from regulatory lists and updating standards in line with modern diagnostic methods to facilitate germplasm exchange and support global agriculture.
The present study reports the ability of a fungal isolate DY1, obtained from rotten wood, to degrade alkali lignin (AL) and lignocelluloses in an efficient manner. The efficiency of degradation was monitored by measuring the percentage of decolorization and utilizing GC-MS for identifying degradation products at different time intervals (10, 20, 30, and 40 days). The optimal degradation of alkali lignin (AL) was achieved at 0.

In this study, we performed cross-sectional surveys using large-scale patient and caregiver data to identify the prevalence and average impact of symptoms and symptomatic themes experienced by adults with AD, MCI, and dementia. Subsequent analyses were used to determine which demographic and disease-specific factors are associated with more severe disease.
