Vegetative compatibility, host range and pathogenicity of Verticillium dahliae isolates in Iran

Verticillium wilt is an economically important disease which inflicts serious losses in potato, cotton, alfalfa, some vegetable crops and fruit trees and occasionally ornamentals. Verticillium dahliae, infected cultivated species and weeds were collected from several areas in Iran during tewelve years from 1993-2005 and studied for their vegetative compatibility, host range and pathogenecity. T...

Leafspot of Peanut Associated with Magnesium Deficiency.

It is generally recognized that the susceptibility and prevalence of manv plant diseases are associated with plant nutrition. The peanut plant is susceptible to leafspot infection which becomes economicallv important during the last half of its growth period when the crop is planted in the spring. The severity and rapid spread of infection in the field may not be due to the mere presence of the...

Host Range and Emerging and Reemerging Pathogens

An updated literature survey identified 1,407 recognized species of human pathogen, 58% of which are zoonotic. Of the total, 177 are regarded as emerging or reemerging. Zoonotic pathogens are twice as likely to be in this category as are nonzoonotic pathogens. Emerging and reemerging pathogens are not strongly associated with particular types of nonhuman hosts, but they are most likely to have ...

Influenza receptors, polymerase and host range.

Influenza infection is initiated by virus attachment to sialic acid-containing cell-surface receptors. The spectrum of sialylglycoconjugates varies substantially between viral host species as well as target tissues and cell types of the same species, leading to variations in the receptor-binding specificity of viruses circulating in these hosts. Therefore, receptor specificity plays an importan...
