Ochratoxin A commonly occurs in many grains, other feedstuffs, and in soil but in low concentrations, and Abortion or fetal death, though occurring in rodents, are unlikely to be induced in cattle.
Isolation and partial characterization of a mycotoxin from Penicillium roqueforti.
Purification studies guided by this test led to the isolation of a major toxin which showed intraperitoneal and oral median lethal dose values in weanling rats of 11 and 115 mg/kg, respectively.
Expression of two sucrose synthetase genes in endosperm and seedling cells of maize: evidence of tissue specific polymerization of protomers
The results from immuno-blot analyses show that the Sh encoded sucrose synthetase-1 protein (SS-1) is indeed present in seedlings and provides a new dimension and a useful tool for the analysis of many sh mutants and their revertants due to various transposable elements.

Highly morphogenic callus cultures were isolated from stamens of a wild peanut species, Arachis paraguariensis, and grafting to stems of rooted seedlings was used to obtain plants from regenerated shoots.
Relationship of Ochratoxin A to Foetal Death in Laboratory and Domestic Animals
Investigations of the possibility that feed contaminated with mycotoxin is a cause of previously undiagnosed bovine abortion induced foetal death and resorption in the test animals.
A strain of peanut mottle virus seedborne in bambarra groundnut.
Peanut mottle virus (PMoV) was detected in nine of 95 bambarra groundnut plants grown in Florida from seed produced in Africa and induced systemic mosaic symptoms in cultivars of peanut, lima bean, and pea.
cDNAs of two non-allelic sucrose synthase genes in maize: cloning, expression, characterization and molecular mapping of the sucrose synthase-2 gene
Interestingly, restriction endonuclease sites around the 3′ ends are more conserved than the 5′ ends of these two genes, which indicates sequence diversity over the entire lengths of Ss2 and Sh clones.
Penicillium stoloniferum virus: large-scale concentration and purification by polyethylene glycol.
An experimental procedure developed to concentrate fungal viruses from large volumes of homogenized mycelia with water-soluble polymers, such as polyethylene glycol, possesses advantages over more…
Patulin inhibition of mycovirus replication in Penicillium stoloniferum.
Results indicated that the mycotoxin patulin can block mycovirus replication, and no-proliferating fungal mycelium is capable of continued support of PsV-F replication, which is sensitive to patulin.
Penicillium stoloniferum virus: altered replication in ultraviolet-derived mutants.
Nine phenotypic mutants of the wild type of Penicillium stoloniferum NRRL5267 were obtained from conidia exposed to ultraviolet light for 60 min (10% survival), and virus levels ranged from 85 to 150 E-260 units (extinction units at 260 nm in I cm cell) per 4-7 to 5-3 g dry weight of mycelium for the mutant strains.
