Biochemical characterization of phosphoenolpyruvate carboxykinases from multiple species of brown algae. [PDF]

J Phycol
Abstract Phosphoenolpyruvate carboxykinase (PEPCK) is involved in the conversion of phosphoenolpyruvate (PEP) to oxaloacetate (OAA). In addition to playing a role in gluconeogenesis in various organisms, PEPCK also functions in the C4 cycle to concentrate CO2 for photosynthesis in some C4 plants.

Unraveling the drivers of forage quality variation in the Serengeti. [PDF]

Ecology
Abstract Variation in forage quality is a key dimension of herbivore resource partitioning, but the main determinants of such variation across environmental gradients remain poorly understood. It is especially unclear how much variation in plant nutrient contents and stoichiometry is driven by plant species turnover versus by intraspecific variation ...
