Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Establishment of Honey Mesquite and Huisache on a Native Pasture [PDF]

Journal of Range Management, 1982
Scarified honey mesquite [Prosopis julqiora (Swartz) DC. var. ghzndulosa (Torr.) Cockerell] and huisache [haciafarnesiana(L.) Willd.] seeds were broadcast on a native pasture to study their ability to establish plants under several mechanical and chemical treatments. Plots were subjected to mowing, disking, or herbicide treatments.
