first report of powdery mildew of rosa persica caused by leveillula taurica from iran
during the study of powdery mildew related to erysiphaceae family from abardeh region in mashhad (khorasan-e-razavi province), one species of rose (rosa persica michx.ex juss, summer 2006) with symptoms of powdery mildew was collected. the symptoms observed with the naked eye including the dense cottony shape mycelia infected the leaf surfaces as well as some parts of the stem. mycelia were den...
متن کاملSpermidine Uptake by Mitochondria of Helianthus tuberosus.
In the present work evidence is provided that spermidine, a polyamine largely present in plant tissues, may be transported, at physiological concentrations, into the matrix space of mitochondria isolated from tubers of Helianthus tuberosus L. cv OB1 (Jerusalem artichoke). It is concluded that the movement of spermidine strictly depends on membrane potential, since it is drastically blocked by v...
متن کاملResponse of Several Apple Varieties to Powdery Mildew (podosphaera Leucotricha) Attack in Central Transylvania Conditions
The response of apple cultivars to powdery mildew attack – Podosphaera leucotricha (Ell. et Everh.) Salm. – on leaves and shoots, for seven years (1990-1996), emphasised a large variability for this character existing within 75 apple varieties tested in an experimental field at the Fruit Research Station in Cluj-Napoca, Central Transylvania, Romania. The experimental results confirmed that the ...
متن کاملFactors Affecting Airborne Concentrations of Podosphaera xanthii Conidia and Severity of Gerbera Powdery Mildew
To determine the factors affecting airborne conidial concentrations of Podosphaera xanthii Braun and Shishkoff and powdery mildew severity in greenhouse-grown potted gerbera (Gerbera jamesonii H. Bolus), airborne concentrations of conidia were monitored in a glass and polyethylene greenhouse. Temperature, relative humidity, and leaf wetness were recorded onsite, and the percentage of foliage wi...
متن کاملThe Podosphaera xanthii haustorium, the fungal Trojan horse of cucurbit-powdery mildew interactions.
The powdery mildew fungi are obligate biotrophic plant pathogens that develop a specialized structure for parasitism termed haustorium, which is responsible for nutrient uptake and factor exchange with the plant. In this work, we present a detailed microscopy analysis of the haustoria of the cucurbit powdery mildew fungus Podosphaera xanthii, a major limiting factor for cucurbit production worl...
