Attack by the host powdery mildew Erysiphe cichoracearum usually results in successful penetration and rapid proliferation of the fungus on Arabidopsis. By contrast, the nonhost barley powdery mildew Blumeria graminis f. sp. hordei (Bgh) typically fails to penetrate Arabidopsis epidermal cells. In both instances the plant secretes cell wall appositions or papillae beneath the penetration peg of...
بلوط مهمترین و فراوانترین گونه درختی موجود در غرب ایران به ویژه منطقه زاگرس محسوب میشود. کنهها از بندپایان فعال در جنگل های بلوط میباشند که نقش های متفاوتی از جمله آفت، شکارگر و تجزیه کننده به عهده دارند .به منظور بررسی فون کنه های پیش استیگمای مرتبط با جنگل بلوط .Quercus spp در منطقه حفاظت شده بیستون، نمونه برداری های متعددی از نقاط مختلف منطقه در سال های 1397 و 1398 ...

Powdery mildew on flowers of Cassia fistula and folioles Tamarindus indica, caused by Erysiphe quercicola, is reported for the first time in Brazil. The identity pathogen was confirmed morphological characteristics molecular sequence analyses ITS 28S rDNA regions. This report E. quercicola causing powdery C. T. indica

(in Schlechtendalia 4: 5. 2000) (≡ 1912) is a common, widespread, and almost cosmopolitan powdery mildew oaks. It pathogen of eco...
drying characteristics of quercus were determined experimentally as a function of temperature, air velocity, and variety (quercus persica and quercus libani). in order to estimate and select a suitable drying curve, five different thin layer drying models were fitted to the experimental data. experiments were performed at the air temperatures of 50, 60 and 70°c. at each temperature level, two a...
TAXI-I (Triticum aestivum xylanase inhibitor I) is a wheat grain protein that inhibits arabinoxylan fragmentation by microbial endo-beta-1,4-xylanases used in the food industry. Although TAXI was speculated to be involved in counterattack against pathogens, there is actually no evidence to support this hypothesis. We have now demonstrated the presence of TAXI family members with isolation of tw...
Previously isolated susceptible host mutants were used in a genetic and functional study of the resistance response of barley specified by resistance gene Mla12 to the fungal pathogen Erysiphe graminis f sp hordei. Mutant M66 represents a defective allele of Mla12, whereas M22, M82, and M100 represent mutations in loci unlinked to Mla12. Intermutant crosses of the latter three show that suscept...
Accumulation of potentiometric and other dyes in haustoria of Erysiphe graminis in living host cells
Twenty-five vital fluorescent dyes were tested for accumulation in haustoria of Erysiphe graminis (DC) Merat f. sp. hordei Em . Marchai when applied to coleoptile epidermal host cells of Hordeum vulgare L . Eight of the dyes gave fluorescence to structures judged to be haustorial mitochondria . The potentiometric cyanine dyes, DiOC4 (3) and DiOC 7 (3) gave best differentiation between the putat...
