Symbiosis constraints: Strong mycobiont control limits nutrient response in lichens

Ecology and Evolution, 2017
Symbioses such as lichens are potentially threatened by drastic environmental changes. We used the lichen Peltigera aphthosa—a symbiosis between a fungus (mycobiont), a green alga (Coccomyxa sp.), and N2‐fixing cyanobacteria (Nostoc sp.)—as a model ...

Longitudinal Analysis of Oral Potentially Malignant Disorder Conversion to Malignancy

The Laryngoscope, EarlyView.
ABSTRACT Objectives Oral potentially malignant disorders (OPMDs) are local and systemic conditions that can result in oral malignancies. We have had an OPMD surveillance program for 25 years covering over 30% of our state's population. More recent electronic health record search techniques have allowed us to analyze over 1500 patients in over a 10‐year

Does Palsa Thaw in Northern Finland Contribute to Remobilisation of Metals Accumulated in Peat Into Surface Waters?

Land Degradation &Development, EarlyView.
ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Characterization and Expression Analysis of the Sterol C-5 Desaturase Gene PcERG3 in the Mycobiont of the Lichen Peltigera canina Under Abiotic Stresses

Microbiology Research
Lichens, symbiotic organisms with a high tolerance to harsh environments, possess a greater diversity of sterols than other organisms. Sterols are involved in maintaining membrane integrity, hormone biosynthesis, and signal transduction.
