VICTORIAE REGINAE ET IMPERATRICI

Viruses of Helminthosporium (Cochlioblus) victoriae.

The enigma of the transmissible disease of Helminthosporium victoriae has almost been resolved. Diseased isolates are doubly infected with two distinct viruses, the victorivirus Helminthosporium victoriae virus 190S and the chrysovirus HvV145S. Mixed infection, however, is not required for disease development. DNA transformation experiments and transfection assays using purified HvV190S virions...

Electron Cryo-Microscopy Studies of Helminthosporium victoriae Virus 190S.

The parasitic nature of viruses is a source of intense interest owing to the wide variety of potential hosts, which include humans, livestock, fungi, agricultural crops, as well as many others [1]. Viruses are differentiated by variations in properties such as size, capsid morphology, genomic composition, replication strategy, and host target [1, 2]. The family Totiviridae of dsRNA viruses is c...

گیاه‌‌پالایی کادمیوم توسط نهال‌های یک‌ساله آکاسیا ویکتوریا (Acacia victoriae L.)

استفاده ازگیاهان برای پالایش خاک‌های آلوده به ‌فلزات سنگین راه‌کاری اقتصادی و موثر می‌باشد. گیاه‌پالایی از جمله روش‌های پیشنهادی است که با انباشت عناصر سنگین در گیاهان، خروج این عناصر از خاک‌های آلوده را امکان‌ پذیر می‌کند. به ‌همین منظور در این پژوهش مقاومت و اثر جذب فلز کادمیوم بر روی نهال‌های یک‌ساله Acacia victoriae با چهار غلظت از م...

Respiratory oxygen consumption among groups of Pseudocrenilabrus multicolor victoriae subjected to different oxygen concentrations during development

The routine metabolic rate of Pseudocrenilabrus multicolor victoriae, laboratory-reared, F1 offspring of parents collected from a hypoxic swamp, did not differ between sibs raised under normoxia and hypoxia. In the offspring of parents originating from a river where the oxygen levels were generally high but fluctuating, the metabolic rate of fish raised under normoxia was higher than for sibs r...
