Lolium

grass genus of the family Poaceae; toxic when infested with anguina lolii, clavibacter toxicus, Neotyphodium, Pithomyces, endoconidium temulentum or may contain toxic amounts of nitrate. Includes L. multiflorum (L. italicum, Italian rye grass), L. perenne (perennial rye), L. rigidum (Wimmera rye grass), L. temulentum (darnel, drake).

Lolium perenne
a staple grass for permanent pastures. It is not in itself poisonous, except that it does contain high concentrations of alkaloids, e.g. perloline, at some times and may accumulate nitrate. There are doubts about the pathogenicity of these compounds. The diseases that do occur on perennial rye grass pastures are ryegrass staggers and facial eczema. Called also perennial ryegrass.
Lolium rigidum
an annual pasture grass of great productivity. Its seeds may be parasitized by a gall-inducing grass nematode Anguina lolii, and if it is accompanied by a Clavibacter toxicus which produces tunicaminyluracils (corynetoxins), it is very poisonous. Ataxia, convulsions and death are the common signs. Called also Wimmera rye grass.
Lolium temulentum
varying reports on the toxicity of this grass may be because the poisoning is due to a fungal infection, e.g. Endoconidium temulentum. Called also darnel.

Conclusions: The high crude protein and moderate fiber content, along with high IVDMD found in Ammophila arenaria, Trigonella maritima and Vicia monantha, Vicia sativa, Atriplex nummularia, Ononis vaginalis and Lycium shawii suggested that these plants have a greater nutritive value than the highly fibrous and of moderate IVDMD species such as: Lygeum spartum, Lygos raetam, Panicum coloratum, Lolium rigidum, Gymnocarpos decandrum, Deverra trotuosa and Aeluropus lagopoides.

Based on the effects of EF infection in Lolium arundinaceum (tall fescue), we predicted that herbivores would prefer to feed on the E- local Michigan plants.
Effect of drought on the growth of Lolium perenne genotypes with and without fungal endophytes.
Lolium perenne yield 80 days after sowing decreased by 30%, but only in the most compacted plots, and it was much less sensitive to compaction than timothy (Phleum pratense) (Ferrero 1991).

Since the genome of Lolium is closely related to that of Festuca, R genes can potentially be introgressed from ryegrasses to meadow fescue and tall fescue and vice versa by hybridization.
