| Abstract: | Monstera deliciosa (Araceae) is a tropical American rainforest monocotyledon which is well-known as ornamental foliage plant introduced into many parts of the world. Rust disease on M. deliciosa was found in Chifeng, Inner Mongolia in 2019. Morphological characteristics of the rust indicated that it was closely related to Puccinia paullula on Amorphophallus spp. in Philippines. Phylogenetic analysis of the LSU (ribosomal DNA Large Subunit) sequence indicated highly homologous to P. paullula (KY764151 and KX999886). The ITS (Internal Transcribed Spacer) sequence of P. paullula was not found in GenBank except our submission (MK949148). The pathogen was identified as P. paullula f.sp. monsterae based on morphological and molecular evidence. To our knowledge, this is the first report of P. paullula infecting M. deliciosa in north China. |
