Characterization of a Septobasidium sp. Associated with Felt Disease of Schisandra chinensis

ABSTRACT

Extensive disease surveys performed during the summers of 2013 and 2014 in Schisandra chinensis orchards resulted in the finding of a Septobasidium sp. associated with felt disease. The fungus was characterized to be symbiotic with a scale insect (Pseudaulacaspis cockerelli). Morphological and molecular characteristics of the Septobasidium isolates were investigated. The isolates were morphologically and phylogenetically close to S. bogoriense. We tentatively describe this isolate as a Septobasidium sp., mainly because of the limited amount of information available on the internal transcribed spacer region of the ribosomal DNA of Septobasidium spp.
