Molecular and Pathogenic Characterization of Cylindrocarpon-like Anamorphs Causing Root and Basal Rot of Almonds.

ABSTRACT: Three almond nurseries were prospected in the South of Spain (Sevilla) to evaluate the sanitary status of the nursery plant material. Samples consisted of main roots, secondary roots and six-month-old basal stems 'GxN-15', 'Nemaguard', 'Cadaman', 'Rootpac-40' and 'Rootpac-20' rootstocks planted in the soil, and twigs of mother plants from 'Lauranne', 'Guara', 'Marcona', 'Marta' and 'Ferragnes' almond cultivars. Endophytic and potential pathogenic fungi were identified in mother plants and 70 Cylindrocarpon-like anamorph isolates were detected in the root system and basal stems of analyzed rootstocks. Based on partial sequencing of the his3 gene and multilocus phylogenetic analysis of the concatenated ITS, tub2, his3 and tef1-α partial sequences, seven
