DETERGENT-LIKE ACTION OF TETRAPHENYLBORATE ON PHOSPHOLIPID LABELLING IN GUINEA PIG CORTEX SUBFRACTIONS 1

—The addition of 2 × 10 −4 m sodium tetraphenylborate to particulate preparations of guinea pig cerebral cortex increases labelling of phosphatidic acid from Γ-[ 32 P]-ATP two- to four-fold. The effect ‘was observed in all subcellular fractions studied (nuclear, synaptosomal, mitochondrial and microsomal) and is not blocked by the addition of atropine. Changes in phospholipid labelling similar to those induced by tetraphenylborate can be demonstrated with sodium dodecyl sulphate or sodium desoxycholate. It is suggested that tetraphenylborate stimulates lipid labelling by a detergent-like activation of diglyceride kinase.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/65419/1/j.1471-4159.1974.tb06881.x.pd

Response of Mixed C\u3csub\u3e4\u3c/sub\u3e Grasses to Various Multiple Paddock Grazing Strategies

The botanical composition of mixed grass pastures may change during grazing due to the various grazing period/recovery period lengths associated with multiple-paddock grazing strategies. This 4-year study compared changes in relative species composition and basal plant cover of a C4 grass mixture grazed using a nested paddock design to simulate 2, 4, 6 and 12- paddock grazing cells in eastern Nebraska. Total basal plant cover declined from 11.6% prior to grazing to 7.3% after one year of grazing and then remained nearly constant thereafter. Neither relative species composition nor basal density were affected greatly by grazing strategy. Within grazing strategies, however, some changes occurred although high variability made it difficult to detect significant differences among plant species. Across all grazing strategies, switchgrass [Panicum virgatum L.] frequency was inversely related to big bluestem [Andropogon gerardii Vitman] and indiangrass [Sorghastrum nutans (L.) Nash.] while sideoats grama [Bouteloua curtipendula (Michx.) Torr.] was inversely related to little bluestem [Schizachyrium scoparium (Michx.) Nash.] and indiangrass

Response of Warm-Season Grass Pasture to Grazing Period and Recovery Period Lengths

Grazing period and recovery period lengths are key variables influencing grassland production and composition. Systems with short grazing periods and lengthy recovery periods require numerous pastures. Relatively high facility and management costs associated with multiple-pasture systems can be justified only if plant response is favorable and/or if livestock production is improved. This study determined the effects of 4 different combinations of grazing period/recovery period lengths on percentage basal cover (PBC) and relative species composition (RSC) of seeded, warm-season grass pasture
