A whole genome duplication drives the genome evolution of Phytophthora betacei, a closely related species to Phytophthora infestans.

Background: Pathogens of the genus Phytophthora are the etiological agents of many devastating diseases in several high-value crops and forestry species such as potato, tomato, cocoa, and oak, among many others. Phytophthora betacei is a recently described species that causes late blight almost exclusively in tree tomatoes, and it is closely related to Phytophthora infestans that causes the disease in potato crops and other Solanaceae. This study reports the assembly and annotation of the genomes of P.

Effector Repertoire of : In Search of Possible Virulence Factors Responsible for Its Host Specificity.

is an oomycete plant pathogen closely related to It infects tree tomato () in northern South America, but is, under natural conditions, unable to infect potatoes or tomatoes, the main hosts of its sister species . We characterized, and compared the effector repertoires of and other species. To this end, we used approaches to predict and describe the repertoire of secreted proteins in species and determine unique and core effectors.

Genome-Wide Association Study Identifies Single Nucleotide Polymorphism Markers Associated with Mycelial Growth (at 15, 20, and 25°C), Mefenoxam Resistance, and Mating Type in .

Phenotypic diversity among individuals defines the potential for evolutionary selection in a species. epidemics are generally thought to be favored by moderate to low temperatures, but temperatures in many locations worldwide are expected to rise as a result of global climate change. Thus, we investigated variation among individuals of for relative growth at different temperatures.

Wood anatomy of two species of the genus (Clusiaceae: Clusioideae: Clusieae) from the northern Andes of Colombia.

is a genus of neotropical angiosperms distributed in wet and riparian forests from Bolivia to Mexico in altitudes from near sea-level to close to 3000 m. The wood anatomy of two species of the genus was investigated. Branches of mature stems were collected in a secondary wet forest in Colombian Northern Andes.
