Fungi today occur on virtually every plant part, living and dead, and represent a significant proportion of fungal diversity. Arborescent seed ferns characterized by large, tongue-shaped leaves with reticulate venation (Glossopteris) represent the dominant floral element in the Permian of Gondwana. However, documented evidence of fungi associated with the leaves of these plants is exceedingly r...

BACKGROUND Factors influencing the oral flora of premature infants have not been adequately investigated. OBJECTIVE To investigate the effects of gestational age and of anti-bacterial therapy on the oral flora of premature infants. METHODS Oral cultures were obtained at age 1 day and age 10 days from 65 premature infants, divided into three groups: a) 24 neonates of 30-34 weeks gestation wh...

American chestnut was eliminated as a canopy tree from the Appalachian region of North America with the introduction of chestnut blight in the early 1900s. Breeding programs initiated in the 1980s have produced seedling lines that display the pure American morphology with potential resistance to chestnut blight. More work is required to assess their field performance in field sites representati...

this study was performed for evaluation of the qualitative traits of safflower (carthamus tinctorius l.) as affected by azotobacter and mycorrhizal symbiosis (host plant root symbiosis with the glomus fungi) as factorial experiment based on randomized complete block design with three replications in research farm of college of arak islamic azad university during growing season of 2011-2012. tre...

Systemic crop protection using endophytic isolates of entomopathogenic fungi is at the forefront IPM. Nonetheless, any potential trade-offs between virulence and behaviour must be elucidated if they are to effectively used in pest management strategies. Here we investigated adaptation an isolate Beauveria bassiana following successive passage through melon, tomato cotton tissues. Plants were sp...

Inoculation experiments were carried out in pot culture to determine the effects of VA fungi on the growth of Poa bulbosa. In this experiment, four treatments  were  used: 1. Strile soil without  inoculation,  2. Strile soil plus inoculum, 3. Natural soil plus inoculum, and 4. Natural soil without inoculation. Inoculum was prepared from a suspension of mycorrhizal  roots of  Poa  plants (Root c...

ABSTRACT A recent epidemic of Swiss needle cast along the Oregon coast has prompted efforts to quantify foliar infection and colonization of the causal agent Phaeocryptopus gaeumannii. In this paper, we compare four methods to quantify colonization of Douglas-fir foliage by P. gaeumannii: fruiting body abundance, ergosterol content, dot blot analysis, and TaqMan based real-time quantitative pol...

The halophytes Plantago maritima, Aster tripolium, Artemisia santonicum, Puccinellia limosa, Festuca pseudovina and Lepidium crassifolium from two different saline soils of the Hungarian steppe were examined for colonization by arbuscular mycorrhizal fungi (AMF). The salt aster (A. tripolium) and the sea plantain (P. maritima) were examined more thoroughly by recording root colonization paramet...

Study the effects of inoculation with two arbuscular mycorrhizal (AM) fungi, Gm (Glomus mosseae T.H. Nicolson & Gerd.)Gerd & Trappe) and Gi (Glomus intraradices  N.C. Schenck & G.S. Sm.) on the  herb yield, essential oil (EO) content and nutrient acquisition of basil (Ocimum basilicum L.) under drought stress conditions,The experiment conducted with 9 treatments and 4 replications. Drought stre...
