We characterized, and compared the effector repertoires of <i>P. betacei</i> and other <i>Phytophthora</i> species. To this end, we used <i>in silico</i> approaches to predict and describe the repertoire of secreted proteins in <i>Phytophthora</i> species and determine unique and core effectors. <i>P. betacei</i> has the largest proteome and secretome of all <i>Phytophthora</i> species evaluated. We identified between 450 and 1933 candidate effector genes in <i>Phytophthora ramoruFrontiers in genetics579https://www.ebi.ac.uk/biostudies/studies/S-EPMC7295944biostudies-literatureEffector Repertoire of <i>Phytophthora betacei</i>: In Search of Possible Virulence Factors Responsible for Its Host Specificity.PMC7295944Bernal AJAyala-Usma DARojas-Estevez PRestrepo SGuayazan-Palacios NCardenas MUrbina-Gomez DAMideros MFfalseEffector Repertoire of <i>Phytophthora betacei</i>: In Search of Possible Virulence Factors Responsible for Its Host Specificity.<i>Phytophthora betacei</i> is an oomycete plant pathogen closely related to <i>Phytophthora infestans.</i> It infects tree tomato (<i>Solanum betaceum</i>) in northern South America, but is, under natural conditions, unable to infect potatoes or tomatoes, the main hosts of its sister species <i>P. infestans</i>.
