To study the interdependence of sucrose accumulation and its hydrolyzing enzyme, soluble acid invertase (AI; EC 3.2.1.26), in fructan-accumulating temperate grasses and cereals, experiments were performed in which sucrose ...

Linkage maps of perennial ryegrass were constructed from F2 and BC1-type populations using, predominantly, restriction fragment length polymorphism data based on heterologous probes used in mapping other grass species. The ...

Quantitative trait locus (QTL) mapping, which can be a useful tool for dissecting complex traits, has been used here to study the regulation of fructan metabolism in temperate forage grasses. • An F2 mapping family, derived ...

Data from plants transformed to accumulate fructan are assessed in the context of natural concentrations of reserve carbohydrates and natural fluxes of carbon in primary metabolism: Transgenic fructan accumulation is ...

Grassland covers 26% of the world's total land area. It produces feed for livestock; maintains soil fertility; protects and conserves soil and water resources; creates a habitat for wildlife; provides recreational space ...

Valid models are the foundation of systems biology. However, even well-established models may warrant reassessment. A testable feature of the currently accepted vacuolar model for fructan biosynthesis is its independence ...

Improving the available energy in natural fodders is the most desirable way of increasing the nitrogen use efficiency of livestock production. Perennial ryegrass (Lolium perenne) shows considerable genetic variation for ...

The accumulation of total water-soluble carbohydrate, and specifically sucrose and fructan, by excised leaves of Phormium tenax and P. cookianum (family Phormiaceae J. G. Agardh, order Asparagales) was investigated. Total ...

Water-soluble carbohydrate provides an easily fermentable energy source in perennial ryegrass fodder. Previously the considerable genetic variation available within the species has been characterised by quantitative trait ...
