Late blight, caused by the pathogen Phytophthora infestans, is a devastating disease of potato and tomato, but can also damage other solanaceous hosts. To gain a better understanding of the interaction between P. infestans and these other hosts, the susceptibility of species in three solanaceous
Six calibrachoa plants displaying reduced growth, general chlorosis, and blistering on the foliage were purchased from a retail store in Starkville, MS in 2007 and tested for possible virus infections. Transmission electron microscope observations of leaf-dip preparations revealed the presence of
OBJECTIVE
The phylogenetic relationships of Petunia sensu Jussieu (Petunia sensu Wijsman plus Calibrachoa) are unclear. This study aimed to resolve this uncertainty using molecular evidence.
METHODS
Phylogenetic trees of 52 taxa of Petunia sensu Jussieu were constructed using restriction fragment
Calibrachoa mottle virus (CbMV), a tentative carmovirus, was first isolated and reported by Liu et al. (1) from infected Calibrachoa plants. During the spring of 2003, petunia samples from Florida and California sent to testing services at Agdia, Inc (Elkhart IN) tested positive for CbMV by
Spherical virus particles approximately 29 to 31 nm in diameter were isolated from Calibrachoa plants showing leaf mottling and chlorotic blotch symptoms. The virus was mechanically transmitted to Chenopodium amaranticolor, C. capitatum, C. quinoa, Nicotiana benthamiana, and N. clevelandii plants,
