Kelussia odoratissima Mozaff. belonging to the Apiaceae family, is well known for its medicinal and nutritional importance, endemic to Iran. Seed dormancy is a major problem present in Kelussia odoratissima leading to low germination percentage; thus, improvement of seed germination and breaking seed dormancy is important. Piriformospora indica, a root-colonizing endo...

During a survey of myxosporean parasites of cyprinid fish in Hungary, infections caused by unknown Myxobolus spp. were found in the internal organs of rudd, Scardinius erythrophthalmus, and bleak, Alburnus alburnus. Small plasmodia developed in blood vessels of the kidney, liver, testes and intestinal wall. The parasites were studied on the basis of spore morphology and by histological and mole...

Morphological and molecular methods were used to identify the statues of an isolate, EFY-36, a taxolproducing endophytic fungus. Based on the morphology of the fungal colony, the mechanism of spore production and the characteristics of the spores, the isolate is Mucor spp. Furthermore, the analysis of 18S ribosome RNA sequence of the isolate was achieved using PCR technology. The results showed...

animal life on land. The current benchmark for evidence of plants on land is about 450,000,000 years ago (Late Ordovician). Tantalizing microscopic fossils of chemically resistant spore walls occur in land-derived rocks around the world, and predate this Late Ordovician age by over 50,000,000 years (Upper Cambrian) and possibly beyond. Figuring out what kinds of organisms (algae, primitive plan...

The endospore of Bacillus polymyxa was originally described by Meyer (1897) in a study of a bacillus which he designated Astasia asterospora. Meyer's drawings of the spore, showing ridges and the star shaped aspect, were reproduced by Knaysi (1951) over the name Bacillus asterosporus. It has not been generally recognized that this name is synonymous with B. polymyxa (Smith, et al., 1952). So th...

Abstract Bull’s eye rot is a postharvest storage disease of apples. Until now the cause this in New Zealand was not clear. A survey 6880 apples from five regions over two seasons conducted. Neofabraea malicorticis and N. perennans were found. One hundred seventy-nine isolates identified as Phlyctema vagabunda by specific polymerase chain reactions and/or sequencing β-tubulin gene region followe...

Anthracocarpon andinum, a new terricolous species, is described from northern Argentina. The most important differences from A. virescens (Zahlbr.) Breuss are in thallus morphology and size and shape of the ascospores. Anthracocarpon andinum develops a squamulose thallus covered by a sulcate epinecral layer. The squamules of A. virescens are smaller, thinner and covered by a thin and continuous...

Background: Bacillus cereus is a spore-forming food-borne pathogen often associated with food products such as meat, vegetables, soup, rice, and milk and other dairy products. 1 - 20 % of total outbreaks of food intoxication in the world are caused by Bacillus cereus. There is an increasing interest in the use of plant-derived antimicrobial compounds as natural preservatives for foods. Such as ...

Frankia sp., the actinomycetous endophyte in nitrogen-fixing actinorhizal nodules, may differentiate two forms from its hyphae: vesicles and sporangia. In root nodules of Comptonia peregrina (L.) Coult. and Myrica gale L., sporangia may be either absent or present. Nitrogenase activity and symbiotic efficiency were contrasted in spore(+) and spore(-) nodules of these two host genera. Seedlings ...
