Improving phosphorus (P) nutrient efficiency in Lolium perenne (perennial ryegrass) is likely to result in considerable economic and ecological benefits. Byrne et al. employ a 44K barley microarray to study gene expression in Lolium and the results are combined with a metabolic profiling study. Utilization of glycolytic bypasses, remodelling of lipid membranes and P-scavenging are indicated as early response mechanisms to P deficiency.
Perennial ryegrass (Lolium perenne L.) is a key pasture grass in many parts of the world. It is reported to be the most valuable plant species in New Zealand, with a $14.5 billion impact on New Zealand’s GDP in...
Plant regrowth in response to defoliation relies on efficient nitrogen use. Roche et al. find that remobilisation of water soluble carbohydrate stores in leaves of perennial ryegrass (Lolium perenne) is coordinated with...
Genetic linkage maps remain very important tools for gene discovery in many plant species. Whilst several genetic maps exist for perennial ryegrass, it has been difficult to integrate data across studies because of a...
