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

ABSTRACT:

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. betacei P8084, the first of its species, and P. infestans RC1-10, a Colombian strain from the EC-1 lineage, using long-read SMRT sequencing technology.

Results

Our results show that P. betacei has the largest sequenced genome size of the Phytophthora genus so far with 270 Mb. A
