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...

Invasion success of a scarab beetle within its native range: host range expansion versus host-shift

Only recently has it been formally acknowledged that native species can occasionally reach the status of 'pest' or 'invasive species' within their own native range. The study of such species has potential to help unravel fundamental aspects of biological invasions. A good model for such a study is the New Zealand native scarab beetle, Costelytra zealandica (White), which even in the presence of...

Adaptive plasmid evolution results in host-range expansion of a broad-host-range plasmid.

Little is known about the range of hosts in which broad-host-range (BHR) plasmids can persist in the absence of selection for plasmid-encoded traits, and whether this "long-term host range" can evolve over time. Previously, the BHR multidrug resistance plasmid pB10 was shown to be highly unstable in Stenotrophomonas maltophilia P21 and Pseudomonas putida H2. To investigate whether this plasmid ...

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...
