Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Selection of DNA markers for detection of extreme resistance to potato virus Y in tetraploid potato (Solanum tuberosum L.) F1 progenies

Czech Journal of Genetics and Plant Breeding, 2007
Marker-assisted selection is progressively introduced into potato breeding especially in the case of monogenically inherited traits. Varieties and clones with extreme resistance to potato virus Y (PVY) from German, Hungarian, Polish, Dutch and Slovak ...

RAPD PCR Confirms Absence of Genetic Variation Between Insecticide Resistant Variants of the Green Peach Aphid, \u3ci\u3eMyzus Persicae\u3c/i\u3e (Homoptera: Aphididae) [PDF]

, 2017
Previous allozyme analysis has revealed an apparent absence of enzyme variability in the green peach aphid, Myzus persicae (Sulzer). We are interested in determining the genetic relatedness of individual M persicae clones carrying different numbers of ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Segregation of DNA markers of potato (Solanum tuberosum ssp. tuberosum L.) resistance against Ro1 pathotype Globodera rostochiensis in selected F1 progeny

Plant, Soil and Environment, 2002
Marker assisted selection is the fast and objective method for detection of resistance major genes. This method is practical for identification of some candidate genes of quantitative resistance.
