Abstract

Pythium aphanidermatum was found to be associated with rotting of leaves and stems in Lampranthus spectabilis in the summers of 2013 and 2014. Infected plants were initially characterized by water-soaked and discoloured tissue, which are soon covered with cottony aerial hyphae. Subsequently, infected tissues wilted, leaves and stems appeared desiccated, and infected plants died. Pathogenicity of a representative isolate was proved, fulfilling Koch's postulates. Sequence of the internal transcribed spacer region of ribosomal DNA from the isolate shared 100% identity with that of P. aphanidermatum. To our knowledge, this is the first report of P. aphanidermatum causing leaf and stem rot on L. spectabilis in Korea.
