Systemic infection of solanaceous hosts by peanut chlorotic streak caulimovirus is temperature dependent and can be complemented by coinfection with figwort mosaic caulimovirus

Peanut chlorotic streak caulimovirus (PClSV) developed systemically in tobacco (Nicotiana tabacum) and Datura inoxia at 33 C but not at 25 C even though the virus multiplied and was highly productive in the inoculated leaves of these plants at 25 C. In contrast to behavior in these hosts the virus c...

Description
Summary:Peanut chlorotic streak caulimovirus (PClSV) developed systemically in tobacco (Nicotiana tabacum) and Datura inoxia at 33 C but not at 25 C even though the virus multiplied and was highly productive in the inoculated leaves of these plants at 25 C. In contrast to behavior in these hosts the virus caused productive systemic infections at either temperature in Datura stramonium. PClSV was complemented for systemic infection in D. inoxia at 25 C by coinfection with a second caulimovirus, figwort mosaic virus. Gene I (tentative movement function) mutants of PClSV were not complemented for systemic development in D. inoxia at 25 C, suggesting that some other virus function was lacking for systemic development in tobacco and D. inoxia at 25 C
