Fungal endophytes were isolated from asymptomatic and symptomatic plants of Dactylis glomerata sampled in different ecosystems in Spain. Fungi were identified using morphological, as well as molecular methods based on internal transcribed spacer (ITS) and ribosomal DNA sequencing. Molecular data provided a framework for identification and assessing the phylogenetic position of isolates. One hun...

Cocksfoot mottle sobemovirus supports replication and encapsidation of the viroid-like satellite RNA (sat-RNA) of lucerne transient streak virus (LTSV) in two monocotyledonous species, Triticum aestivum and Dactylis glomerata. Additionally, LTSV sat-RNA replicates effectively in the presence of turnip rosette sobemovirus in Brassica rapa, Raphanus raphanistrum and Sinapsis arvensis, but not in ...

Under Mediterranean climates, the best strategy to produce rain-fed fodder crops is to develop perennial drought resistant varieties. Summer dormancy present in native germplasm has been shown to confer a high level of survival under severe drought. Nevertheless it has also been shown to be negatively correlated with annual biomass productivity. The aim of this study was to analyze the correlat...

A nineteen year trial at Lake Tekapo compared the longer term trends of over-drilling legume and grasses into either previous undeveloped tussock country or following a previous legume phase. Tall oat grass (from summer sowing) and cocksfoot (from spring sowing) were the most successful of the sown grasses. They remained a low proportion of the swards but greater with prior herbicide treatment,...

Evolution of genes that specify cytosolic phosphoglucose isomerases (PGIs) has been studied in a natural intraspecific polyploid complex (Dactylis glomerata L.). Analyses of genetic control, polymorphism, and gene expression have been carried out in plants collected from numerous populations that belong to 14 diploid subspecies originating in the middle or at the end of the Tertiary period and ...
