Poisonous Foodgrain: Wheat Mixed with Lolium Temulentum
In the March issue of this journal there appeared under 'Medical News' (p. 148; an abstract from an article by Brinton) an account of an epidemic at Aden caused by the seed of Lolium temulentum, a weed which grows in wheat fields. The wheat was brought from Abyssinia and milled locally by machinery. The consumption of the product made the inhabitants go down with symptoms of acute intoxication....
متن کاملGenetic relationships between Lolium (Poaceae) species revealed by RAPD markers.
The genus Lolium is one of the most important groupings of temperate forage grasses, including about eight recognized species that are native to some temperate and subtropical regions of the northern hemisphere. We examined genetic relationships among 18 accessions representing all Lolium species using RAPD markers. Among 50 random primers that we screened, 13 gave reproducible amplification ba...
متن کاملSurvey and Detection of Endophytic Fungi in Lolium Germ Plasm by Direct Staining and Aphid Assays
Wilson, A. D., Clement, S. L., and Kaiser, W. J. 1991. Survey and detection of endophytic fungi in Lolium germ plasm by direct staining and aphid assays. Plant Dis. 75:169-173. Clavicipitaceous anamorphic endophytes were detected in 28 of 85 accessions from five of eight species in a collection of Lolium germ plasm. Comparative descriptions of endophytic mycelium in seeds of L. multiflorum, L. ...
متن کاملCloning and characterization of a putative fructosyltransferase and two putative invertase genes from the temperate grass Lolium temulentum L.
The invertases of Lolium temulentum have been characterized at the enzyme level. However, studies on the expression of the genes coding for these enzymes have been lacking. To elucidate the role of acid 'invertase-like' genes in sucrose metabolism and carbon partitioning in Gramineae further, three 'invertase-like' homologous clones were isolated from L. temulentum cDNA expression libraries bas...
متن کاملKaryotype asymmetry in Cynodon Rich. (Poaceae) accessions.
Cynodon is a genus of plants with forage potential that has attracted the interest of breeders. These species have high morphological variability in a large number of varieties and cytotypes, hampering identification. This study aimed to determine the karyotype asymmetry index among accessions of Cynodon to discriminate between them. Karyotype symmetry was based on three estimates, which were c...
