Escape from CD8+ T Cell Response by Natural Variants of an Immunodominant Epitope from Theileria parva Is Predominantly Due to Loss of TCR Recognition por Connelley, Timothy K., MacHugh, Niall D., Pellé, Roger, Weir, William, Morrison, W. Ivan

“…Despite this diversity, all natural variants exhibited partial or total escape from immune recognition, which was predominantly due to abrogation of TCR recognition, with mutation resulting in loss of the lysine residue at P8, playing a particularly dominant role in escape. …”

Impact of natural, planted (Pueraria phaseoloides, Leucaena leucocephala) fallow and landuse intensity on weed seedling emergence pattern and density in cassava intercropped with maize por Ekeleme, F., Chikoye, David, Akobundu, I.O.

“…The highest number of weed seedlings emerged early in the season (3–5 WAP) followed by a second but smaller peak flush at 8–9 WAP and a decline over the rest of the sampling period in all types of fallow, landuse intensity, and years except in 1994. Natural bush and L. leucocephala fallow had more weed seedlings than P. phaseoloides fallow in all years except 1993 and 1995. …”

Low 15N Natural Abundance in Shoot Tissue of Brachiaria humidicola Is an Indicator of Reduced N Losses Due to Biological Nitrification Inhibition (BNI) por Karwat, Hannes, Egenolf, Konrad, Nuñez, Jonathan, Rao, Idupulapati M., Rasche, Frank, Arango, Jacobo, Moreta, Danilo, Arévalo, Ashly, Cadisch, Georg

“…We hypothesized that altered nitrification and NO−3 leaching due to diverging BNI magnitudes in contrasting Bh genotypes influence soil 15N natural abundance (δ15N), which in turn is reflected in distinct δ15N in Bh shoot biomass. …”
