Plant fructosyltransferases are highly homologous in primary sequence and typically consist of two subunits but catalyze widely different reactions. Using functional expression in the yeast Pichia pastoris, we show that the substrate specificity of festuca sucrose:sucrose 1--beta-D-fructosyltransferase (1-SST) and barley sucrose:fructan 6--beta-D-fructosyltransferase (6-SFT) is entirely determi...

Research is required on sod to explore the differences in management and postharvest practices help inform producers reduce information inefficiencies that affect supply demand of cool-season turfgrass sod. Replicated field experiments were conducted Indiana Minnesota quantify effect species (strong creeping red fescue [Festuca rubra L. ssp. Gaudin], Chewings [F. commutata tall arundinacea Schr...

Improving water conservation efforts for golf course turf is a constant industry goal. While creeping bentgrass (Agrostis stolonifera L.; CBG) the preferred fairway species throughout most of cool-humid regions, requirements alternative cool-season with better acute drought tolerance at mowing heights (e.g., <0.5 inch) are not well documented. A 2-yr field study compared two irrigation strategi...

Nuclear genome size, as measured by flow cytometry with propidium iodide, was used to investigate the relationships within the genus Gagea (Liliaceae), mainly from the Netherlands. The basic chromosome number for Gagea is x = 12. The inferred ploidy in the Dutch and German accessions varies from diploid to decaploid. Consequently there is a large range of genome sizes (DNA 2C-values) from 14.9 ...

The species within the Lolium/Festuca grass complex have dispersed and colonized large areas of temperate global grasslands both naturally and by human intervention. The species within this grass complex represent some of the most important grass species both for amenity and agricultural use worldwide. There has been renewed interest by grass breeders in producing hybrid combinations between th...

BACKGROUND AND AIMS To improve the management of grass communities, early plant development was compared in three species with contrasting growth forms, a caespitose (Lolium perenne), a rhizomatous (Poa pratensis) and a caespitose-stoloniferous species (Agrostis stolonifera). METHODS Isolated seedlings were grown in a glasshouse without trophic constraints for 37 d (761 degrees Cd). The appea...
