Allantoin: A Potential Compound for the Mitigation of Adverse Effects of Abiotic Stresses in Plants
Plants, 2023 Stress-induced alterations vary with the species of plants, the intensity and duration of the exposure, and stressors availability in nature or soil. Purine catabolism acts as an inherent defensive mechanism against various abiotic stresses and plays a ...

Genes of different catabolic pathways are coordinately regulated by Dal81 in Saccharomyces cerevisiae [PDF]
, 2015 Yeast can use a wide variety of nitrogen compounds. However, the ability to synthesize enzymes and permeases for catabolism of poor nitrogen sources is limited in the presence of a rich one.

Dynamic Epistasis under Varying Environmental Perturbations [PDF]
, 2014 Epistasis describes the phenomenon that mutations at different loci do not have independent effects with regard to certain phenotypes. Understanding the global epistatic landscape is vital for many genetic and evolutionary theories. Current knowledge for

Gut Bacterial Species Distinctively Impact Host Purine Metabolites during Aging in Drosophila
iScience, 2020 Summary: Gut microbiota impacts the host metabolome and affects its health span. How bacterial species in the gut influence age-dependent metabolic alteration has not been elucidated. Here we show in Drosophila melanogaster that allantoin, an end product

Allantoin content in lichens depends on anthropopressure level
Ecological Indicators, 2021 Allantoin has been detected in several plant families but only few papers reported its presence in lichens. The 18 from 21 lichen species we tested contained detectable amount of allantoin with a range of 0.005–13.4 mg/g DW.
