Tomato (Lycopersicon esculentum Mill.) seedlings, susceptible (cv. Pearson A-I Improved) and resistant (cv. Pearson Improved) to race 1 Fusarium oxysporum f. sp. lycopersici (Sacc.) Snyd &Hans., were inoculated with Meloidogyne javanica (Trueb) Chitwood second-stage juveniles and 3 weeks later with race 1 F. oxysporum f. sp. lycopersici spores. One week after fungal inoculation, no fungus was v...

Brown spot disease caused by Alternaria alternata (Fr.: Fr.) Keissl is a serious problem forproduction of tangerines and tangerine hybrids in Iran. The Tangerine pathotype causes brownspot disease on young leaves and immature fruits of limited varieties of mandarins and tangerines(Citrus. reticulata Blanco). Specificity in the interaction between tangerine and the pathogen isdetermined by a hos...

Aim. Studying of the influence avermectin-containing polyfunctional preparations Avercom and Nova on enhancement resistance to fusarium wilt tomato plants in vitro. Methods. Tomato were cultivated vitro for 30 days presence 25 μl/l Nova. Analysis was carried out by spraying with a conidia suspension Fusarium oxysporum f. sp. lycopersici F. solani. Resistance has been evaluated 15 after inoculat...

Eleven Alternaria alternata strains isolated from Red Delicious apples in cold storage in Argentina, were tested for alternariol and alternariol methyl ether production in laboratory media and in whole fresh fruits. Most of them were able to produce both toxins in all media. They were detected also in mycelium free filtrates from liquid cultures and in asymptomatic tissues from inoculated fruit...

Alternaria alternata (Fr.) Keissler strain PPRI 21032 was isolated from onion leaves collected in Roodeplaat, Pretoria, South Africa. The whole genome of this strain was sequenced and produced a total of 33.12 Mb with a GC content of 50.9%. The whole genome comprises 11,701 predicted coding sequences.

Leaf spot disease of rough lemon and brown spot disease of tangerines caused by distinct pathotypes of Alternaria alternata, and postharvest fruit black rot disease caused by A. citri, are the three major fungal diseases of citrus. The pathogenicity and specificity for the pathogens of Alternaria leaf spot and brown spot diseases are associated with the production of different host-specific tox...

This is the first study reporting the evaluation of transgenic lines of tomato harboring rice chitinase (RCG3) gene for resistance to two important fungal pathogens Fusarium oxysporum f. sp. lycopersici (Fol) causing fusarium wilt and Alternaria solani causing early blight (EB). In this study, three transgenic lines TL1, TL2 and TL3 of tomato Solanum lycopersicum Mill. cv. Riogrande genetically...

Selected rice varieties such as BR-78, 80, 81, 82, 83, 84, 86, 87, 88 and 89 were used in this experiment to investigate the prevalence of seed-borne fungi. A total twelve fungi belonging six genera was isolated from seeds selected BRRI (Bangladesh Rice Research Institute) by using tissue planting method. They Alternaria alternata (Fr.) Keissler, Aspergillus flavus Link, A. fumigatus Fresenius,...
